A Taxonomic Investigation of Mycena in California A TAXONOMIC INVESTIGATION OF MYCENA IN CALIFORNIA A thesis submitted to the faculty of San Francisco State University In partial fulfillment of The requirements For the degree Master of Arts In Biology: Ecology and Systematic Biology by Brian Andrew Perry San Francisco, California November, 2002 Copyright by Brian Andrew Perry 2002 A Taxonomic Investigation of Mycena in California Mycena is a very large, cosmopolitan genus with members described from temperate and tropical regions of both the Northern and Southern Hemispheres. Although several monographic treatments of the genus have been published over the past 100 years, the genus remains largely undocumented for many regions worldwide. This study represents the first comprehensive taxonomic investigation of Mycena species found within California. The goal of the present research is to provide a resource for the identification of Mycena species within the state, and thereby serve as a basis for further investigation of taxonomic, evolutionary, and ecological relationships within the genus. Complete macro- and microscopic descriptions of the species occurring in California have been compiled based upon examination of fresh material and preserved herbarium collections. The present work recognizes a total of 61 Mycena species occurring within California, sixteen of which are new reports, and 3 of which represent previously undescribed taxa. I certify that this abstract is a correct representation of the content of this thesis. Dr. Dennis E. Desjardin (Chair, Thesis Committee) Date ACKNOWLEDGEMENTS I am deeply indebted to Dr. Dennis E. Desjardin for the role he has played as a teacher, mentor, advisor, and friend during my time at SFSU and beyond. Dr. Desjardin first introduced me to the amazing world of fungi and instilled in me the desire to become a mycologist, for which I will always be grateful. I would like to thank Dr. Desjardin for encouraging me to tackle the Mycena species of California, as well as the tireless hours he spent with me in the lab and field teaching me about the Agaricales and other fungi. I would also like to thank Dr. Desjardin for the immense amount of patience he displayed during the seemingly endless preparation of this manuscript. I am grateful to Dr. Robert Patterson for his role as a committee member and graduate advisor, as well as teaching me about the vascular plant flora of California. I am also grateful Dr. Greg Spicer for being a committee member, teaching me about phylogenetic systematics, and encouraging me to pursue a PhD. I would also like to thank Dr. Scott Redhead for his correspondence regarding the taxonomy of Mycena species. I would like to thank my labmates and fellow graduate students for making the Biology Department at SFSU such a great place to study biology. In particular I would like to thank Kristin Peterson, Kelly Collins, J.R. Blair, Atik Retnowati, Chuck Bell, Robyn Battaglia, Joshua McDill, and Laura Boykin for their help, encouragement, and friendship. I would also like to thank Michael Wood and Fred Stevens for their continued interest in my thesis project, their companionship on numerous forays, and the use of their beautiful slides of Mycena species. During the course of this study material was borrowed from several institutions, and I would like to thank the following herbaria directors for their assistance: Dr. Robert Fogel of the University of Michigan; Dr. David Largent of Humboldt State University, California; Dr. Donald. H. Pfister of the Farlow Herbarium at Harvard University; and Dr. Scott Redhead of the National Mycology Herbarium, Canada. This project would not have been possible without the collections these herbaria provided. Much of the research presented in this manuscript was made possible by financial assistance from the Mycological Society of San Francisco and the Mycological Society of America. I am very grateful for the assistance these groups provided, and would like to thank them for making such funding opportunities available to students. Finally, I would like thank my wife, Eileen Joy Macapinlac, for all of the support, patience, encouragement, and companionship she continues to provide me with during the course of this and other studies. I would also like to thank my parents, Beverly J. Perry and Richard Perry, for always encouraging me to follow where my interests led me (however strange they may have seemed!). It is to these three people I would like to dedicate the following monograph. iv TABLE OF CONTENTS Introduction..................................................... 1 History and Nomenclature ......................................... 2 History of the Genus in North America ................................ 5 Methods and Materials ............................................ 7 Taxonomically Informative Characters Macromorphological characters................................ 9 Micromorphological characters ............................... 14 Key to California Sections of Mycena ................................ 18 Taxonomic treatment of the sections of Mycena section Oregonenses ....................................... 23 section Fragilipedes ........................................ 24 section Luculentae ......................................... 50 section Rubromarginatae.................................... 56 section Sanguinolentae ..................................... 67 section Galactopoda ....................................... 71 section Longisetae ......................................... 74 section Heimales .......................................... 75 section Aciculae ........................................... 80 section Adonidae .......................................... 82 section Lactipedes ......................................... 87 section Hygrocyboideae..................................... 89 section Fuliginellae ........................................ 96 section Basipedes ........................................ 100 section Amictae .......................................... 103 section Insignes .......................................... 105 section Supinae .......................................... 107 section Polyadelphia ...................................... 109 section Sacchariferae ..................................... 111 section Mycena .......................................... 115 section Calodontes ....................................... 125 section Testudini ......................................... 128 section Intermediae ....................................... 130 section Cinerellae ........................................ 132 section Filipedes ......................................... 141 Literature Cited ................................................ 151 Species Index ................................................. 157 v INTRODUCTION The recent increase in issues of biodiversity, especially those pertaining to the management and conservation of natural resources, underscores the need for baseline knowledge of the organisms functioning in our ecosystems. Unlike mammals, birds, and plants, which appear to be fairly well documented for much of the Northern Hemisphere, groups such as fungi remain relatively unknown for many regions due to their ephemeral nature, and the numerous difficulties that have traditionally been associated with their identification. One such difficulty is the lack of accessible, up-to-date monographs including keys to species identification and detailed species descriptions. Commonly, when monographs do exist for a given group or genus, they tend to cover a very large geographic area and therefore include a high number of species, often making it difficult to identify a given collection to a single species with any degree of certainty. Fortunately, recent investigations have been published which document the diversity of distinct groups and genera of Agaricales within the restricted range of California (Thiers, 1997; Shanks, 1997; Methven, 1997; Desjardin, 1987; Kerrigan, 1986). However, many more genera are relatively poorly known taxonomically, and remain to be investigated. The genus Mycena (Pers. Fr.) Roussel, which is a member of the large family Tricholomataceae, remains largely undocumented in California, as well as many other regions of the United States. The genus is characterized by a white spore print; smooth, hyaline spores; adnate to arcuate or decurrent lamellae; a thin membranous pileus; intricate cystidia; and a hypodermium composed of large, inflated hyphae. Members of the genus are almost exclusively saprotrophic, the exception being a single species [M. citricolor (Ber. & Curt.) Sacc.] reported to be pathogenic on Coffea (Singer, 1986), and two species reported to form mycorrhizal associations with distinct species of the Orchidaceae (Guo et al., 1997). In the field, the basidiomes of Mycena species are commonly encountered growing upon the debris of conifers and woody angiosperms, decaying logs and branches, lignicolous on the bark of living trees, in soil, and more rarely (at least in California) on the debris of ferns, grasses, or other herbaceous plants, or among mosses or grasses. The most recently published material relating to the genus within California is limited to Dr. Alexander Smith’s monograph on North American species of Mycena, published in 1947, and R. A. Maas Geesteranus’ (1992) investigation of Mycena species described from the northern hemisphere. However, both of these works pertain to a very large geographic range, and neither attempt to present a complete survey of the Mycena species found

ISSN (online) 2154-8889 MYCOTAXON http://dx.doi.org/10.5248/121.393 Volume 121, pp. 393–403 July–September 2012 Laccariopsis, a new genus for Hydropus mediterraneus (Basidiomycota, Agaricales) Alfredo Vizzini*, Enrico Ercole & Samuele Voyron Dipartimento di Scienze della Vita e Biologia dei Sistemi - Università degli Studi di Torino, Viale Mattioli 25, I-10125, Torino, Italy *Correspondence to: [email protected] Abstract — Laccariopsis (Agaricales) is a new monotypic genus established for Hydropus mediterraneus, an arenicolous species earlier often placed in Flammulina, Oudemansiella, or Xerula. Laccariopsis is morphologically close to these genera but distinguished by a unique combination of features: a Laccaria-like habit (distant, thick, subdecurrent lamellae), viscid pileus and upper stipe, glabrous stipe with a long pseudorhiza connecting with Ammophila and Juniperus roots and incorporating plant debris and sand particles, pileipellis consisting of a loose ixohymeniderm with slender pileocystidia, large and thin- to thick-walled spores and basidia, thin- to slightly thick-walled hymenial cystidia and caulocystidia, and monomitic stipe tissue. Phylogenetic analyses based on a combined ITS-LSU sequence dataset place Laccariopsis close to Gloiocephala and Rhizomarasmius. Key words — Agaricomycetes, Physalacriaceae, /gloiocephala clade, phylogeny, taxonomy Introduction Hydropus mediterraneus was originally described by Pacioni & Lalli (1985) based on collections from Mediterranean dune ecosystems in Central Italy, Sardinia, and Tunisia. Previous collections were misidentified as Laccaria maritima (Theodor.) Singer ex Huhtinen (Dal Savio 1984) due to their laccarioid habit. The generic attribution to Hydropus Kühner ex Singer by Pacioni & Lalli (1985) was due mainly to the presence of reddish watery droplets on young lamellae and sarcodimitic tissue in the stipe (Corner 1966, Singer 1982).

    Checklist of the Argentine Agaricales 4. Tricholomataceae and Polyporaceae 1 2* N. NIVEIRO & E. ALBERTÓ 1Instituto de Botánica del Nordeste (UNNE-CONICET). Sargento Cabral 2131, CC 209 Corrientes Capital, CP 3400, Argentina 2Instituto de Investigaciones Biotecnológicas (UNSAM-CONICET) Intendente Marino Km 8.200, Chascomús, Buenos Aires, CP 7130, Argentina CORRESPONDENCE TO *: [email protected] ABSTRACT— A species checklist of 86 genera and 709 species belonging to the families Tricholomataceae and Polyporaceae occurring in Argentina, and including all the species previously published up to year 2011 is presented. KEY WORDS—Agaricomycetes, Marasmius, Mycena, Collybia, Clitocybe Introduction The aim of the Checklist of the Argentinean Agaricales is to establish a baseline of knowledge on the diversity of mushrooms species described in the literature from Argentina up to 2011. The families Amanitaceae, Pluteaceae, Hygrophoraceae, Coprinaceae, Strophariaceae, Bolbitaceae and Crepidotaceae were previoulsy compiled (Niveiro & Albertó 2012a-c). In this contribution, the families Tricholomataceae and Polyporaceae are presented. Materials & Methods Nomenclature and classification systems This checklist compiled data from the available literature on Tricholomataceae and Polyporaceae recorded for Argentina up to the year 2011. Nomenclature and classification systems followed Singer (1986) for families. The genera Pleurotus, Panus, Lentinus, and Schyzophyllum are included in the family Polyporaceae. The Tribe Polyporae (including the genera Polyporus, Pseudofavolus, and Mycobonia) is excluded. There were important rearrangements in the families Tricholomataceae and Polyporaceae according to Singer (1986) over time to present. Tricholomataceae was distributed in six families: Tricholomataceae, Marasmiaceae, Physalacriaceae, Lyophyllaceae, Mycenaceae, and Hydnaginaceae. Some genera belonging to this family were transferred to other orders, i.e. Rickenella (Rickenellaceae, Hymenochaetales), and Lentinellus (Auriscalpiaceae, Russulales).

  • Appendix K. Survey and Manage Species Persistence Evaluation
    Appendix K. Survey and Manage Species Persistence Evaluation Establishment of the 95-foot wide construction corridor and TEWAs would likely remove individuals of H. caeruleus and modify microclimate conditions around individuals that are not removed. The removal of forests and host trees and disturbance to soil could negatively affect H. caeruleus in adjacent areas by removing its habitat, disturbing the roots of host trees, and affecting its mycorrhizal association with the trees, potentially affecting site persistence. Restored portions of the corridor and TEWAs would be dominated by early seral vegetation for approximately 30 years, which would result in long-term changes to habitat conditions. A 30-foot wide portion of the corridor would be maintained in low-growing vegetation for pipeline maintenance and would not provide habitat for the species during the life of the project. Hygrophorus caeruleus is not likely to persist at one of the sites in the project area because of the extent of impacts and the proximity of the recorded observation to the corridor. Hygrophorus caeruleus is likely to persist at the remaining three sites in the project area (MP 168.8 and MP 172.4 (north), and MP 172.5-172.7) because the majority of observations within the sites are more than 90 feet from the corridor, where direct effects are not anticipated and indirect effects are unlikely. The site at MP 168.8 is in a forested area on an east-facing slope, and a paved road occurs through the southeast part of the site. Four out of five observations are more than 90 feet southwest of the corridor and are not likely to be directly or indirectly affected by the PCGP Project based on the distance from the corridor, extent of forests surrounding the observations, and proximity to an existing open corridor (the road), indicating the species is likely resilient to edge- related effects at the site.

GRIFFITH3, DILUKA PEIRIS1 1School of Life Sciences, University of Westminster, 115 New Cavendish Street, London, W1M 8JS 2Natural History Museum, Cromwell Road, London, SW7 5BD 3Institute of Biological Environmental and Rural Sciences, University of Aberystwyth, SY23 3DD Corresponding author, e-mail: [email protected] ABSTRACT The results of four five-day field surveys of fungi carried out yearly on Lundy from 2004-08 are reported and the results compared with the previous survey by ourselves in 2003 and to records made prior to 2003 by members of the LFS. 240 taxa were identified of which 159 appear to be new records for the island. Seasonal distribution, habitat and resource preferences are discussed. Keywords: Fungi, ecology, biodiversity, conservation, grassland INTRODUCTION Hedger & George (2004) published a list of 108 taxa of fungi found on Lundy during a five-day survey carried out in October 2003. They also included in this paper the records of 95 species of fungi made from 1970 onwards, mostly abstracted from the Annual Reports of the Lundy Field Society, and found that their own survey had added 70 additional records, giving a total of 156 taxa. They concluded that further surveys would undoubtedly add to the database, especially since the autumn of 2003 had been exceptionally dry, and as a consequence the fruiting of the larger fleshy fungi on Lundy, especially the grassland species, had been very poor, resulting in under-recording. Further five-day surveys were therefore carried out each year from 2004-08, three in the autumn, 8-12 November 2004, 4-9 November 2007, 3-11 November 2008, one in winter, 23-27 January 2006 and one in spring, 9-16 April 2005.

The new species is pathogenic to taro and this is the first record of Marasmiellus on Colocasia esculenta . Agaricales / Basidiomycota / parasitic fungi / taxonomy INTRODUCTION The genus Marasmiellus Murrill is a large genus (c. 400 names in the CABI index). It is well-known in South America especially since a monograph by Singer (1973a). Several Marasmiellus species were also published by e.g. Dennis (1961, 1968, 1970),Pegler (1983, 1997), and Singer (1969, 1989). Recently, a severe disease of Colocasia esculenta (L.) Schott (taro) was observed in Espírito Santo State,Brazil. Colocasia esculenta is a tropical plant of the family Araceae , originated in South Central Asia and it is presently grown worldwide (Irwin et al ., 1998; Plucknett, 1983). It is one of the oldest cultivated crops and is grown for its edible corms and leaves. In Espírito Santo State, it is grown on most family farms and is often intercropped or rotated with other crops for several years and it is normally sold in Farmers’ market.

Even the most subtle differences are the visible characteristics which may relatively small fruit bodies, as in in spore size or cap coloration have their be grouped in (1) morphological (shape, Flammulina velutipes or Hygrophorus place in identifying mushrooms and size) and (2) physiological (pigments, hypothejus. Generally, species fruiting other fungi. Quite many mycologists are taste, smell, toxicity, etc.).
