A Survey of Fungi at the University of Wisconsin-Waukesha Field Station Alan D. Parker Department of Biological Sciences University of Wisconsin-Waukesha Waukesha, Wisconsin 53188 Introduction The University of Wisconsin-Waukesha Field Station was founded in 1967 through the generous gift of a 98 acre farm by Ms. Gertrude Sherman. The facility is located approximately nine miles west of Waukesha on Highway 18, just south of the Waterville Road intersection. The site consists of rolling glacial deposits covered with old field vegetation, 20 acres of xeric oak woods, a small lake with marshlands and bog, and a cold water stream. Other communities are being estab- lished as a result of restoration work; among these are mesic prairie, oak opening, and stands of various conifers. A long-term study of higher fungi and Myxomycetes, primarily from the xeric oak woods, was started in 1978.

Received: 3 March 2020; Accepted: 12 March 2020; Published: 16 March 2020 Abstract: Auricularia heimuer is one of the most popular edible fungi in China. In this study, the whole genome of A. heimuer was sequenced on the Illumina HiSeq X system and compared with other mushrooms genomes. As a wood-rotting fungus, a total of 509 carbohydrate-active enzymes (CAZymes) were annotated in order to explore its potential capabilities on wood degradation. The glycoside hydrolases (GH) family genes in the A. heimuer genome were more abundant than the genes in the other 11 mushrooms genomes. The A. heimuer genome contained 102 genes encoding class III, IV, and V ethanol dehydrogenases. Evolutionary analysis based on 562 orthologous single-copy genes from 15 mushrooms showed that Auricularia formed an early independent branch of Agaricomycetes. The mating-type locus of A. heimuer was located on linkage group 8 by genetic linkage analysis.

  • 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.

Mycosphere 6(3), 290–326, Doi 10.5943/mycosphere/6/3/7 Abstract The Dothideomycetes include several genera whose ascomata can be considered as apothecia and thus would be grouped as discomycetes. Most genera are grouped in the family Patellariaceae, but also Agrynnaceae and other families. The Hysteriales include genera having hysterioid ascomata and can be confused with species in Patellariaceae with discoid apothecia if the opening is wide enough. In this study, genera of the family Patellariaceae were re-examined and characterized based on morphological examination. As a result of this study the genera Baggea, Endotryblidium, Holmiella, Hysteropatella, Lecanidiella, Lirellodisca, Murangium, Patellaria, Poetschia, Rhizodiscina, Schrakia, Stratisporella and Tryblidaria are retained in the family Patellariaceae. The genera Banhegyia, Pseudoparodia and Rhytidhysteron are excluded because of differing morphology and/or molecular data.

  • Dreams and Nightmares of Latin American Ascomycete Taxonomists
    DREAMS AND NIGHTMARES OF NEOTROPICAL ASCOMYCETE TAXONOMISTS Richard P. Korf Emeritus Professor of Mycology at Cornell University & Emeritus Curator of the Cornell Plant Pathology Herbarium, Ithaca, New York A talk presented at the VII Congress of Latin American Mycology, San José, Costa Rica, July 20, 2011 ABSTRACT Is taxonomic inquiry outdated, or cutting edge? A reassessment is made of the goals, successes, and failures of taxonomists who study the fungi of the Neotropics, with a view toward what we should do in the future if we are to have maximum scientific and societal impact. Ten questions are posed, including: Do we really need names? Who is likely to be funding our future research? Is the collapse of the Ivory Tower of Academia a dream or a nightmare? I have been invited here to present a talk on my views on what taxonomists working on Ascomycetes in the Neotropics should be doing. Why me? Perhaps just because I am one of the oldest ascomycete taxonomists, who just might have some shreds of wisdom to impart. I take the challenge seriously, and somewhat to my surprise I have come to some conclusions that shock me, as well they may shock you. OUR HISTORY Let's take a brief view of the time frame I want to talk about. It's really not that old. Most of us think of Elias Magnus Fries as the "father of mycology," a starting point for fungal names as the sanctioning author for most of the fungi. In 1825 Fries was halfway through his Systema Mycologicum, describing and illustrating fungi on what he could see without the aid of a microscope.

The present work deals with the non-sequestrate Ascomycota, of which 42 species were found on Mt Wellington. Key Words: Macrofungi, Mt Wellington (Tasmania), Ascomycota, cup fungi, disc fungi. INTRODUCTION For the purposes of this survey, all Ascomycota having a conspicuous fruiting body were considered, excluding Two earlier papers in the preliminary documentation of the endophytes.
