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.

Of these, 130 species were seen or collected in the field and 59 species were recorded from moist chamber cultures. Data analysis based on the species accumulation curve estimates that 75–83% of the total species richness has been recorded, among which 118 species are classified as rare (frequency < 0.5%) and 7 species as abundant (> 3% of all records). Among the 120 first species records for the Altay Mts. are 6 new records for Russia. The southeastern Altay taiga community assemblages appear highly similar to other taiga regions in Siberia but differ considerably from those documented from arid regions. The complete and comprehensive illustrated report is available at http://www.Mycotaxon.com/resources/weblists.html. Key words ― biodiversity, ecology, slime moulds Introduction Although we have a solid knowledge about the myxomycete diversity of coniferous boreal forests of the European part of Russia (Novozhilov 1980, 1999, Novozhilov & Fefelov 2001, Novozhilov & Lebedev 2006, Novozhilov & Schnittler 1997, Schnittler & Novozhilov 1996) the species associated with this vegetation type in Siberia are poorly studied.

    Some Critically Endangered Species from Turkey

    Fungal Conservation issue 4: February 2014 Fungal Conservation Note from the Editor This issue of Fungal Conservation is being put together in the glow of achievement associated with the Third International Congress on Fungal Conservation, held in Muğla, Turkey in November 2013. The meeting brought together people committed to fungal conservation from all corners of the Earth, providing information, stimulation, encouragement and general happiness that our work is starting to bear fruit. Especial thanks to our hosts at the University of Muğla who did so much behind the scenes to make the conference a success. This issue of Fungal Conservation includes an account of the meeting, and several papers based on presentations therein. A major development in the world of fungal conservation happened late last year with the launch of a new website (http://iucn.ekoo.se/en/iucn/welcome) for the Global Fungal Red Data List Initiative. This is supported by the Mohamed bin Zayed Species Conservation Fund, which also made a most generous donation to support participants from less-developed nations at our conference. The website provides a user-friendly interface to carry out IUCN-compliant conservation assessments, and should be a tool that all of us use. There is more information further on in this issue of Fungal Conservation. Deadlines are looming for the 10th International Mycological Congress in Thailand in August 2014 (see http://imc10.com/2014/home.html). Conservation issues will be featured in several of the symposia, with one of particular relevance entitled "Conservation of fungi: essential components of the global ecosystem”. There will be room for a limited number of contributed papers and posters will be very welcome also: the deadline for submitting abstracts is 31 March.

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.

    DISSERTATION Titel der Dissertation Molecular Phylogeny and Taxonomy of the Physarum notabile Species Complex (Myxomycetes) Verfasser Mikhail Okun angestrebter akademischer Grad Doctor of Philosophy (PhD) Wien, 2014 Studienkennzahl lt. A 094 490 Studienblatt: Dissertationsgebiet lt. Molekulare Biologie Studienblatt: Betreut von: Univ.-Prof. Dr. Arndt von Haeseler 2 Abstract Im Gegensatz zu Tieren und Pflanzen sind die Modelle der Verbreitung von mikroskopischen Organismen eher schlecht erforscht. Der Grund dafür sind ihre geringe Größe und bestimmte Merkmale des Lebenszyklus. Zur selben Zeit trägt die geringe Größe zusammen mit der hohen ökologischen Toleranz zur weltweiten Verbreitung der Mikroorganismen bei. In letzter Zeit wurden die Modelle des Kosmopolitismus (Fenchel, 2005; Fenchel, Finlay, 2004; Finlay, Fenchel, 2004) sowie des „Moderate Endemism“ (Foissner, 2006) im Bezug auf Mikroorganismen öfters diskutiert (Fontaneto, 2011; Martiny et al., 2006). Um diese Fragen genauer zu studieren, sind Modell-Mikroorganismen benötigt, die leicht im Feld sowohl auch im Labor identifiziert werden. Eine solcher Gruppen sind die Myxomyceten (Eumycetozoa). Die Gruppe beinhaltet ca. 1000 Spezies in 5 Ordnungen (Martin, Alexopoulos, 1969; Olive, 1975). Als aktive Bakteriophagen sind Myxomyceten wichtige Regulatoren der bakteriellen Biota in Böden. Die Erforschung der Phylogenie der Myxomyceten trägt dazu bei, die evolutionäre Geschichte der Protisten besser zu verstehen (Adl et al., 2012). Bis vor kurzem basierte das taxonomische System der Myxomyceten fast ausschließlich auf den morphologischen Eigenschaften der Fruchtkörper (Sporokarpen) (Martin, Alexopoulos, 1969; Schnittler et al., 2012) und das morphologische Spezies-Konzept wurde überwiegend benutzt. Erst im letzten Jahrzehnt wurden die Ergebnisse von molekularen Studien an Myxomyceten veröffentlicht (Fiore-Donno et al., 2008). Dennoch ist das taxonomische System der Myxomyceten sehr unstabil (Schnittler et al., 2012).

    Fungal Conservation issue 4: February 2014 First steps in myxomycete conservation activities Tetyana Krivomaz Email [email protected] Myxomycetes an ideal model for building conservation strategy Slime moulds are eukaryotic, phagotrophic, fungus-like organisms, which living nearly in all terrestrial ecosystems. In previous systems slime molds include several groups: Myxomycetes -“true slime moulds”, Protosteliomycetes – microscopic relatives of Myxomycetes, Dictyosteliomycetes –soil inhabitants, Copromyxida – animal dung inhabitants, Acrasida – with individual independent cells that can act as one organism, Plasmodiophoromycota – cell parasitic species. All this groups have a plasmodial stage in their life cycle. Modern systems recognize only Dictyosteliomycetes, Protosteliomycetes and Myxomycetes (Adl et al., 2012). Copromyxida belong to the same phylogenic branch as Amoebozoa. No close relatives are known for Acrasida and Plasmodiophoromycota. The conservation strategy model begins with Myxomycetes, characterized by a remarkable transformation from an animal-like to a fungus-like form. These organisms develop very rapidly, have a high reproductive potential, and seem to possess effective dispersal mechanisms. Myxomycetes tend to be rather inconspicuous. Most parts of the myxomycete life cycle exist as vegetative stages, mobile free- living plasmodia that typically thrive in cool and shady moist places. They feed on bacteria, protozoa, yeast cells, fungi, organic remains etc. After a period of feeding and growth, fruiting bodies develop in drier and more exposed locations. Most are relatively ephemeral. They contain numerous spores which can be dispersed by wind and will eventually germinate and develop into a plasmodium under suitable conditions. Myxomycetes spend a portion of their life cycle in a state where their very presence in a given habitat can be exceedingly difficult if not impossible to determine.

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.
