“…Recent knowledge based on published and our own data (Balabanoff 1967;Zeller 1966Zeller , 1968Evolceanu and Alteraş 1967;and Larcher et al 2003) suggests that nitrogen-rich soils and guano in caves of temperate and sub-Mediterranean Europe are colonized by numerous nonpathogenic Chrysosporium spp., including species with tuberculate conidia superficially resembling A. capsulatus. Among them, C. speluncarum, which forms a natural group with R. flavissima, represents a common saprobe in caves of Central and Southeastern Europe.…”

A new species, Chrysosporium speluncarum, obtained from bat guano in caves in the Czech Republic, Slovakia, and Romania, is described, based on phenotype and rDNA sequences. It possesses tuberculate conidia similar to the Histoplasma anamorph of Ajellomyces capsulatus, but it is not dimorphic, does not grow at 37°C, lacks microconidia, and is nonpathogenic and nonkeratinolytic. All studied characteristics suggest a close relationship with Renispora flavissima. The morphologically similar C. chiropterorum, another species known from the bat environment, is a relative of C. lobatum and Polytolypa hystricis, but is distinct from A. capsulatus and C. speluncarum. The affinity for bats and the presence of conidia with prominent tuberculations has originated convergently in several groups of onygenalean fungi. In addition, the occurrence of fungi mimicking A. capsulatus in caves of temperate Europe is reviewed.

A broad spectrum, total of 195 microfungal taxa, were isolated from various cave substrates (cave air, cave sediments, bat droppings and/or guano, earthworm casts, isopods and diplopods faeces, mammalian dung, cadavers, vermiculations, insect bodies, plant material, etc.) from the cave system of the Domica Cave (Slovak Karst National Park, Slovakia) using dilution, direct and gravity settling culture plate methods and several isolation media. Penicillium glandicola, Trichoderma polysporum, Oidiodendron cerealis, Mucor spp., Talaromyces flavus and species of the genus Doratomyces were isolated frequently during our study. Estimated microfungal species diversity was compared with literature records from the same substrates published in the past.Keywords: Domica Cave system, microfungi, air, sediments, bat guano, invertebrate traces, dung, vermiculations, cadavers DESCRIPTION OF STUDIED CAVESThe Domica Cave system is located on the southwestern edge of the Silická Plateau in the Slovak Karst National Park, close to the state border with Hungary. Geographic coordinates of the Domica Cave entrance are 48 o 28'43'' N and 20 o 28'22'' E, and its entrance is counted in the land-register of the village Kečovo 10 km south of the town Plešivec, at the southern foothill of Domica Hill, 339 m a.s.l. The Domica Cave is connected with the chasm-like Čertova diera Cave (the Devil's Pit Cave) and together with the Stará Domica Cave (the Old Domica Cave) and the Dlhá Chodba Cave (Long Passage Cave -a corridor between Domica and Baradla caves) they reach a length of 5,358 m. They also form one generic unit with the Baradla Cave in Hungary with a total length of about 25 km, from which almost one quarter is in Slovak territory. Currently, the show cave is 1,315 m. The cave was formed in the Middle Triassic by pale Wetterstein limestones of the Silica Nappe along the tectonic faults by corrosive and erosive activities of the Styx stream and the Domický Brook and smaller underground tributaries draining water mainly from the non-karst part of the basin. Air temperature ranges from 10.2 to 11.4 °C and relative humidity from 95 to 98 %. The cave system is an important wintering place for bats.

Substrates relevant for Arthroderma spp., such as keratin rich soils ( Dawson 1963 , Weitzman & Summerbell 1995 ), bird nests ( Otčenášek et al 1967 , Hubálek 1970 ), animal faeces ( Kuehn 1960 , Currah et al 1996 ), or caves ( Kajihiro 1965 , Evolceanu & Alteraş 1967 , Zeller 1970 , Lorch et al 2013 , 2015 ) were not well-represented in the GlobalFungi Database. Overall, the majority of Arthroderma diversity originated from strains/sequences associated with animal substrates, while the number of phylotypes identified from soil samples was low ( Fig.…”

Arthroderma is the most diverse genus of dermatophytes, and its natural reservoir is considered to be soil enriched by keratin sources. During a study on the diversity of dermatophytes in wild small rodents in the Czech Republic, we isolated several strains of Arthroderma. To explore the diversity and ecological significance of these isolates from rodents (n = 29), we characterised the strains genetically (i.e., sequenced ITS, tubb and tef1α), morphologically, physiologically, and by conducting mating experiments. We then compared the rodent-derived strains to existing ITS sequence data from GenBank and the GlobalFungi Database to further investigate biogeography and the association of Arthroderma species with different types of environments. In total, eight Arthroderma species were isolated from rodents, including four previously described species (A. crocatum, A. cuniculi, A. curreyi, A. quadrifidum) and four new species proposed herein, i.e., A. rodenticum, A. simile, A. zoogenum and A. psychrophilum. The geographical distribution of these newly described species was not restricted to the Czech Republic nor rodents. Additional isolates were obtained from bats and other mammals, reptiles, and soil from Europe, North America, and Asia. Data mining showed that the genus has a diverse ecology, with some lineages occurring relatively frequently in soil, whereas others appeared to be more closely associated with live animals, as we observed in A. rodenticum. Low numbers of sequence reads ascribed to Arthroderma in soil show that the genus is rare in this environment, which supports the hypothesis that Arthroderma spp. are not soil generalists but rather strongly associated with animals and keratin debris. This is the first study to utilise existing metabarcoding data to assess biogeographical, ecological, and diversity patterns in dermatophytes.
