Further Studies on Corticolous Myxomycetes from Within FURTHER STUDIES ON CORTICOLOUS MYXOMYCETES FROM WITHIN THE CITY LIMITS OF ATLANTA, GEORGIA A THESIS SUBMITTED TO THE FACULTY OF ATLANTA UNIVERSITY IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY BY LEVESTER PENDERGRASS DEPARTMENT OF BIOLOGY ATLANTA, GEORGIA Y 1976 -1 ABSTRACT B IOLOGY PENDERGRASS, LEVESTER 13.5., Morris College, 1969 M.S.,, Atlanta University, 1972 Further Studies on Corticolous Myxomycetes from Within the City Limits of Atlanta, Georgia Advisor: Dr. Lafayette Frederick Doctor of Philosophy degree conferred May 17, 1976 Thesis dated May, 1976 During a two—year period, beginning in the summer of 1973 and ending in the summer of 1975, a study was conducted on myxomycete bionta from bark of living trees growing in five widely separated localities within the Atlanta city limits. The objectives of the study were to determine (1) whether bark of living trees is a natural substratum for certain kinds of myxomycetes; (2) whether certain myxomycetes manifest affinities for certain species of trees; (3) whether seasonal variations exist in corticolous myxomycete occur rence; and (4) whether any correlation exists between the distribu tion of corticolous myxomycetes and tree habitats. Since two earlier studies of limited scope represent the only reports of systematic studies on corticolous myxomycetes of Georgia, a need has existed for more extensive information on this myxomycete bionta of the state. This study was undertaken in order to fulfill 111 that need. To accomplish the objectives a total of 171 trees, repre senting 12 genera and 21 species, growing in five selected areas within the city limits of Atlanta, were chosen for the study. The genus and species of the trees used were Acer g4o and A. sacchari— num, Carya illinoensis and C. ovata, Cedrus deodara, Cornus florida, Diospyros virginiana, Liquidambar styraciflua, Liriodendron tulipif era, Ostrya virginiana, Pinus echinata and P. taeda, Prunus serotina, Quercus alba, Q. falcata, Q. nigra, Q. phellos, Q. stellata, and Q. velutina, Ulmus alata and U. americana. The five different localities used in this study included three relatively undisturbed wooded areas and two open park areas. The localities were (1) a wooded area in the Highpoint section; (2) a wooded hillside in the Collier Heights section; (3) a wooded ravine in the Beecher Circle section; and (4) two city parks, namely, Washington and Piedmont Parks. Specific plots were selected within each locality for sampling. Each plot was approximately 15 meters square and contained at least one tree of each species that was to be studied. In two of the localities, viz., Collier Heights and Beecher Circle, fallen debris on the forest floor was periodically examined in the field. Five different techniques were used to create conditions favor able for myxomycete development. These techniques were as follows: (1) a modification of the moist chamber technique originally used by Gilbert and Martin; (This modification involved the gradual soaking of bark pieces in sterile petri dishes by adding small volumes of sterile water intermittently as it was absorbed by the bark, This iv practice reduced the possibility of spores being discarded, as may happen when the method of Gilbert and Martin is used.) (2) the plac ing of bark samples in polyethylene bags and attaching these bags to the sides of the trees from which they were collected; (Sterile distilled water was added to the bags in order to first saturate the bark pieces and subsequently maintain a high humidity.) (3) the removal of bark samples from trees and the incubation of these samples in petri dish moist chambers that were left in the field at the base of the tree from which the samples were removed; (4) the attaching of large water—filled polyethylene bags to trees at about breast height; (The bags were perforated at the bottom by puncturing the corners and the middle with a few pin holes. This enabled water to slowly drip onto the bark below the bag and consequently keep the trunk in that region continuously moist.) and (5) the periodic examination of undisturbed bark of standing trees with a lOX hand lens in a search for naturally developing slime molds. Field examinations of leaf litter were also made in order to determine whether myxomycetes that developed in moist chamber on bark samples also developed naturally on plant debris on the forest floor. A total of 46 species of myxomycetes was found during the two years of the study. Forty species of myxomycetes, representing 16 genera, appeared on collected bark samples during the course of the study, and six other species representing six genera were found on field observed leaf litter. The following species of myxomycetes were found: ya carnea, A. cinerea and A. nutans, Badhamia nitens and B. obovata, metallica, fruticulosa, v j j H F-h jw H- rt d H- CD CD F-h H- CD- H lcD 5 ‘—s H CD S CD CD 0 H H 0 CD H V H- H- CD IH- H • CD H H- CD 0 CD CD H CF CD CD H H’ H d H- CD CD 0 F- CD CD CD H- H- H CD H <1 > Ci) F-h CD H CD CD CD < H H H CD H H- CD- Irt CD CD 0 H H’ CD 5 Ci) Ci) H 0 CD CD CD CD H H’ H’ rt H CD Ci) Ci) CF H CD CD CD S Cl) 0 Ci) CF 0 CD CD CD CD CD H CD Hi H CD 0 H- H- 0 H CD CD CD Ci) CD Ci) CD H’ H CD- t- H CD Ci) 0 Ci) C) CD H CD CD H CF Ci) 0 CD Ci) F-h Hi CD 0 CD H CD CD CD CD CD H 0 Hi CD Hi CD H 0 CD H’ CD CD CD CD CD S H CF CF CD CD 0 H’ S CD- CD CD H CF t CD- CD Hi 0 CD Hi CD- CD 5 5 S H- CF Hi H H 5 CD CD Hi CF Ci) H CD 0 H CD- CD CD CD- H’ CD CD CD CD CD CD S CD CD 0 CD M Ci) H’ H H CD CD j CD CD CD- Ci) H CD CD CD H CD CD - Ci) H H- CD lZ Hi CD H CD lCD- H CD H’ CD IC’) CD H, CD • H CD- 0 CD IC’) S - CD CD CD CD IC) CD 0 Hi S CD CD IC) CD CD Ci) ‘ Hi CD CD CD CD lH CD Ci) CD - CD CD ‘ Hi CD H- CD 5 Ci) Ci) Hi CD H lCD H CD F-h 5 Ci) Hi F-h H- IH’ CD H- CD.

Among the country’s fungal species, about 4,698 species belonging to 1,031 genera are currently known or described, of which only a small number of myxomycetes were included. At the UPLB-MNH Mycological Herbarium, one of the country’s premier depository institutions of fungal collections, only about 446 myxomycete specimens were recorded. In this review paper, progress made in myxomycete diversity in the Philippines is reported. The conservation status of the myxomycetes specimens deposited at the UPLB-MNH Mycological Herbarium is also assessed. Furthermore, hindrances to the discovery of new myxomycete species and challenges encountered by local researchers are also discussed. Keywords: myxomycetes, slime molds, biodiversity, conservation INTRODUCTION The Philippines is a vast archipelago of 7,107 islands located in the Southeast Asian region. Some 50 million years ago, the islands rose from the tectonic plates in the Pacific. Its coastlines now can be up to 17,500 km. Only the island of Palawan is believed to be previously connected to Mainland Asia (Vesilind, 2002).

The goal of this study was to document all reported collections of myxomycetes (slime molds) from Athens County, OH (USA). The compilation of several published and unpublished studies of myxomycete records from Athens County resulted in a total of 52 species. The species were distributed among 6 orders, 9 families, and 25 genera and represent 24% of the myxomycetes known from Ohio and approximately 15% of those recorded for North America. No new collections for the state of Ohio were reported. OHIO J SCI 102 (2):27-29, 2002 INTRODUCTION both authors.

Protozoan fungal analogues. Mycosphere 4(4), 794–807, Doi 10.5943/mycosphere/4/4/15 Abstract Records of Egyptian fungi are scattered through a wide array of journals, books, dissertations, and preliminary annotated checklists and compilations. By screening all available sources of information, it was possible to delineate 61 taxa, including 3 varieties, belonging to 29 genera of protozoan fungal analogues that have been reported from Egypt. A provisional key to the identification of reported taxa is given. This is the first species list of protozoan fungus-like analogues from Egypt. Key words – Amoebozoa – biodiversity – Cercozoa – documentation – Liceida – Mycobiota – Physarum Introduction For Egypt, only very few comprehensive assessments of local fungi have been published (e.g. El-Abyad and Abu-Taleb 1993; El-Abyad 1997; Abdel-Azeem, 2010). Documentation of the Egyptian fungi may be dated back to 4500 B.C., when ancient Egyptians produced a number of hieroglyphic reliefs of plants (many of which are psychedelic) on walls and within texts throughout Egypt (Abdel-Azeem 2010). Abdel-Azeem has traced the history of scientific work with fungi in Egypt from its earliest beginnings, almost 200 years ago, through to the present day and published a full review of the history of mycology in Egypt, together with updated assessment of 2281 species of fungi for the country, and an expectation of future perspectives for mycology in Egypt.

Mycosphere 7(4), 473–491, Doi 10.5943/mycosphere/7/4/7 Abstract This guide is an attempt to consolidate all information concerning the biology of the Echinosteliales, including uniform species descriptions for all of the species, and to make this available to interested persons in an open access journal. The Echinosteliales are a small group of myxomycetes with relatively minute sporangia and a unique plasmodial trophic stage (a protoplasmodium). These protoplasmodia, which are a defining characteristic of the order, are relatively small (20-150 μm in diameter) amoeboid stages with sluggish protoplasmic streaming and plasmodial movement which, as far as it is known, do not form a reticulum or undergo fusion with other plasmodia, but do undergo binary plasmotomy after reaching an upper size limit with each plasmodium produces a single sporangium. The minute sporangia produce a relatively limited number of spores and, except for one stalk-less species, they have a distinctive stalk consisting of a fibrillose tube having amorphous material in the lower region and closing at the upper end to produce a solid region. This morphology, along with developmental and DNA studies indicate that this order is probably the evolutionary basal group of the dark-spored myxomycetes.

    A KEY TO THE CORTICOLOUS MYXOMYCETES. David W. Mitchell This key was published in Bulletin of the British Mycological Society Part I: Bull. BMS 12 (1)April 1978 Part II Bull. BMS 12 (2) October 1978 Part III: Bull. BMS 13(1) April 1979 The present document is designed to be printed out as an A5 booklet, to mimic the formatting of the original, hence the blank pages at the back. A KEY TO THE CORTICOLOUS MYXOMYCETES. Part I. David W. Mitchell The Corticolous Myxomycetes comprise a group of slime-moulds that grow primarily, if not exclusively, on the bark of living trees (Keller and Brooks, 1973) with representatives from the five endosporous Orders.The slime-moulds that live in this habitat are small and are difficult to detect in the field, their small size enabling them to take rapid advantage of short periods of rainy weather. This characteristic of rapid development may be used by the mycologist who wishes to study them for, when bark is wetted and placed in a damp chamber, plasmodia quickly become active and sporulate in response to the humid conditions provided. Gilbert and Martin (1933) inadvertently launched the bark culture method when they set up damp chambers to demonstrate the algae that grew on the bark of living trees to their botany classes. They found, to their surprise, that many sporangia of two undescribed species of slime-moulds had grown on the surface of the bark. Since that time, the moist chamber method has become well established in the study of Myxomycetes for it has the advantage of simplicity and often produces a rewarding variety of species even at times of the year when there is little else around to interest the mycologist.

In memoriam Irina O. Dudka Abstract The traditional classification of the Myxomycetes (Myxogastrea) into five orders (Echinosteliales, Liceales, Trichiales, Stemonitidales and Physarales), used in all monographs published since 1945, does not properly reflect evolutionary re- lationships within the group. Reviewing all published phylogenies for myxomycete subgroups together with a 18S rDNA phylogeny of the entire group serving as an illustration, we suggest a revised hierarchical classification, in which taxa of higher ranks are formally named according to the International Code of Nomenclature for algae, fungi and plants. In addition, informal zoological names are provided. The exosporous genus Ceratiomyxa, together with some protosteloid amoebae, constitute the class Ceratiomyxomycetes. The class Myxomycetes is divided into a bright- and a dark-spored clade, now formally named as subclasses Lucisporomycetidae and Columellomycetidae, respectively.
