Protozoologica Special Issue: Protists in Soil Processes
Acta Protozool. (2012) 51: 201–208 http://www.eko.uj.edu.pl/ap ActA doi:10.4467/16890027AP.12.016.0762 Protozoologica Special issue: Protists in Soil Processes Review paper Ecology of Soil Eumycetozoans Steven L. STEPHENSON1 and Alan FEEST2 1Department of Biological Sciences, University of Arkansas, Fayetteville, Arkansas, USA; 2Institute of Advanced Studies, University of Bristol and Ecosulis ltd., Newton St Loe, Bath, United Kingdom Abstract. Eumycetozoans, commonly referred to as slime moulds, are common to abundant organisms in soils. Three groups of slime moulds (myxogastrids, dictyostelids and protostelids) are recognized, and the first two of these are among the most important bacterivores in the soil microhabitat. The purpose of this paper is first to provide a brief description of all three groups and then to review what is known about their distribution and ecology in soils. Key words: Amoebae, bacterivores, dictyostelids, myxogastrids, protostelids. INTRODUCTION that they are amoebozoans and not fungi (Bapteste et al. 2002, Yoon et al. 2008, Baudalf 2008).

Myxomycetes NMW 2012Orange, Updated KS 2017.Docx
Myxomycete (Slime Mould) Collection Amgueddfa Cymru-National Museum Wales (NMW) Alan Orange (2012), updated by Katherine Slade (2017) Myxomycetes (true or plasmodial slime moulds) belong to the Eumycetozoa, within the Amoebozoa, a group of eukaryotes that are basal to a clade containing animals and fungi. Thus although they have traditionally been studied by mycologists they are distant from the true fungi. Arrangement & Nomenclature Slime Mould specimens in NMW are arranged in alphabetical order of the currently accepted name (as of 2012). Names used on specimen packets that are now synonyms are cross referenced in the list below. The collection currently contains 157 Myxomycete species. Specimens are mostly from Britain, with a few from other parts of Europe or from North America. The current standard work for identification of the British species is: Ing, B. 1999. The Myxomycetes of Britain and Ireland. An Identification Handbook. Slough: Richmond Publishing Co. Ltd. Nomenclature follows the online database of Slime Mould names at www.eumycetozoa.com (accessed 2012). This database is largely in line with Ing (1999). Preservation The feeding stage is a multinucleate motile mass known as a plasmodium. The fruiting stage is a dry, fungus-like structure containing abundant spores. Mature fruiting bodies of Myxomycetes can be collected and dried, and with few exceptions (such as Ceratiomyxa) they preserve well. Plasmodia cannot be preserved, but it is useful to record the colour if possible. Semi-mature fruiting bodies may continue to mature if collected with the substrate and kept in a cool moist chamber. Collected plasmodia are unlikely to fruit. Specimens are stored in boxes to prevent crushing; labels should not be allowed to touch the specimen. -
A Survey of Myxomycetes from the Black Hills of South Dakota and the Bear Lodge Mountains of Wyoming
Proceedings of the South Dakota Academy of Science, Vol. 89 (2010) 45 A SURVEY OF MYXOMYCETES FROM THE BLACK HILLS OF SOUTH DAKOTA AND THE BEAR LODGE MOUNTAINS OF WYOMING A. Gabel1*, E. Ebbert2, M. Gabel1 and L. Zierer2 1Biology Department Black Hills State University 1200 University Spearfish, South Dakota 57799 2Deceased *[email protected] ABSTRACT Fruiting bodies of slime molds were collected intermittently from the field from 1990-2009. During the summers of 2007-2009 slime molds also were cultured in moist chambers from downed, decaying wood, dried deciduous leaf litter, and dried grass litter that was gathered three times each summer from four areas at each of the following six sites. Alabaugh Canyon and Boles/Redbird Canyons were dry, prairie/woodlands in Fall River and Custer Counties in the southern Black Hills. Pony Gulch and Spring Creek, in the central hills were moist, broad gulches in Pennington County, and the northern hills sites were Botany Bay and Grigg’s Gulch, narrow, moist canyons in Lawrence County. Contents of a total of 648 cultures were examined. Presence of a species in a culture was considered to be a collection and some cultures contained more than one species. Eighty-two species from both field and culture surveys were identified, and 62 are considered as new records for the Black Hills, and 61 for western South Dakota. Six hundred fifty-seven collections representing 65 spe- cies developed in culture included species from all orders of Myxomycetes. Only five species occurred at a relative abundance > 5% and 20 occurred only once. -
The Occurrence of Myxomycetes on Different Decay Stages of Trunks of Picea Abies, Pinus Sylvestris and Betula Spp. in a Small Oldgrowth Forest in Southern Finland
Karstenia 42: 13- 22, 2002 The occurrence of myxomycetes on different decay stages of trunks of Picea abies, Pinus sylvestris and Betula spp. in a small oldgrowth forest in southern Finland TARJA UKKOLA UKKOLA, T. 2002: The occurrence of myxomycetes on different decay stages of trunks of Picea abies, Pinus sylvestris and Betula spp. in a small oldgrowth forest in southern Finland. - Karstenia 42: 13- 22. Helsinki. ISSN 0453-3402. The occurrence of myxomycetes was studied on fallen trunks of Picea abies, Pinus sylvestris, and Betula spp. (B. pendula and B. pubescens) in a small oldgrowth forest in southern Finland in May 1998 - September 1999. The study site is located in Luukkaa Recreation Area, and was left in pristine state in 1966. The sample trunks were chosen to represent different stages of decomposition and checked every second or fourth > eek in all for 17 times. A total of 325 myxomycete specimens representing 44 taxa in 16 genera were observed. Four taxa, Comatricha pulchella var. fusca, Lycogala exiguum, Licea cf. pus ilia, and Physarum bethelii are new records to Finland. During the study, myxomycetes were most abundant on decomposing trunks of Betula spp. (123 specimens), especially on well-decayed trunks. The species diversity was about the same on all studied tree species: 27 taxa were recorded on P abies and P sylvestris, and 22 on Betula spp. The largest di ersity was on two pine trunks with fairly soft wood (a total of 19 taxa). The common myxomycetes, Ceratiomyxa fruticulosa and Lycogala epidendrum, represent generalists in this study, being abundant and present at nearly all decay stages of all studied tree species. -
Slime Moulds
Queen’s University Biological Station Species List: Slime Molds The current list has been compiled by Richard Aaron, a naturalist and educator from Toronto, who has been running the Fabulous Fall Fungi workshop at QUBS between 2009 and 2019. Dr. Ivy Schoepf, QUBS Research Coordinator, edited the list in 2020 to include full taxonomy and information regarding species’ status using resources from The Natural Heritage Information Centre (April 2018) and The IUCN Red List of Threatened Species (February 2018); iNaturalist and GBIF. Contact Ivy to report any errors, omissions and/or new sightings. Based on the aforementioned criteria we can expect to find a total of 33 species of slime molds (kingdom: Protozoa, phylum: Mycetozoa) present at QUBS. Species are Figure 1. One of the most commonly encountered reported using their full taxonomy; common slime mold at QUBS is the Dog Vomit Slime Mold (Fuligo septica).

Various problems in recording myxomycetes and analysis of their diversity are discussed by the examples taken from tundra, boreal, and arid areas of Russia and Kazakhstan. Recent advances in inventory of some regions of these areas are summarised. A rapid technique of moist chamber cultures can be used to obtain quantitative estimates of myxomycete species diversity and species abundance. Substrate sampling and species isolation by the moist chamber technique are indispensable for myxomycete inventory, measurement of species richness, and species abundance. General principles for the analysis of myxomycete diversity are discussed. Key words: slime moulds, Mycetozoa, Myxomycetes, biodiversity, ecology, distribu- tion, habitats Introduction decay (Madelin, 1984). The life cycle of myxomycetes includes two trophic stages: uninucleate myxoflagellates General patterns of community structure of terrestrial or amoebae, and a multi-nucleate plasmodium (Fig. 1). macro-organisms (plants, animals, and macrofungi) are The entire plasmodium turns almost all into fruit bodies, well known.

Mycosphere 6(3), 356–384, doi 10.5943/mycosphere/6/3/11 Abstract A total of 299 substrate samples collected throughout the Sultanate of Oman were analyzed for myxomycetes and myxomycete-like organisms (MMLO) with a combined approach, preparing one moist chamber culture and one agar culture for each sample. We recovered 8 forms of Myxobacteria, 2 sorocarpic amoebae (Acrasids), 19 known and 6 unknown taxa of protostelioid amoebae (Protostelids), and 50 species of Myxomycetes. Moist chambers and agar cultures completed each other. No method alone can detect the whole diversity of myxomycetes as the most species-rich group of MMLO. A significant overlap between the two methods was observed only for Myxobacteria and some myxomycetes with small sporocarps. -

Novozhilov2 and Ludmila V. Chistiakova3 1 Biological and Soil Science Faculty of St. Petersburg State University, St. Petersburg, Russia, 2 Komarov Botanical Institute, Russian Academy of Sciences, St. Petersburg, Russia, 3 Biological Research Institute of St. Petersburg State University, St. Petersburg, Russia Summary The ultrastructure of zoospores of the myxogastrids Symphytocarpus impexus B. Ing et Nann.Bremek. (Stemoniida), Arcyria cinerea (Bull.) Pers. (Trichiida), and Lycogala epidendrum (L.) Fr. (Liceida) is reported for the first time, with special reference to flagellar apparatus. The cytoskeleton in all three species includes microtubular and fibrillar rootlets arising from both basal bodies of the flagellar apparatus. There is a similarity in the presence and position of the rootlets N15 between our species and other studied species of myxogastrids and protostelids. Thus, general conservatism of cytoskeletal characters and homology among eumycetozoa have been confirmed for these taxa. At the same time there is variation in the details of flagellar rootlets’ structure in different orders and genera. The differences concern the shape of short striated fibre (SSF) which is an organizing structure for microtubular rootlets r2, r3 and r4. Its upper strand is more prominent in L. epidendrum. The fibrillar part of rootlet 1 is connected to basal body 1 in S. impexus, to basal body 2 in A. cinerea, and to both basal bodies in L. epidendrum. The rootlets r4 and r5 are very conservative and consist, correspondigly, of 7 and 2 microtubules in all three species. -

The Myxomycetes of Athens Conty, Ohio
The Myxomycetes of Athens County, Ohio1 DAKKIN L. RUIJINO2 AND JAMKS C. CAVI;NI)KR, Department of Environmental and Plant Biology, Ohio University, Athens, OH 45701 ABSTRACT. 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.
