“…van Oorschot & Samson, and Sepedonium spp., which can be confused with the Chrysosporium state of R. flavissima and, by extension, also with C. speluncarum. The first two of these are known to be associated with bat guano in Israel, Italy, and Romania (Ajello et al 1965(Ajello et al , 1977Evolceanu and Alteraş 1967), but their similarity with C. speluncarum does not reflect their phylogenetic relatedness (Campbell et al 2006;Vidal et al 2000). C. speluncarum possesses tuberculate conidia similar to C. vallenarense Oorschot & Piontelli.…”

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.

“…Carmich. (anamorph of Aphanoascus), C. lobatum Scharapov, C. merdarium, C. pannicola (Corda) Oorschot & Stalpers, and C. pseudomerdarium Oorschot, isolated from guano and nitrogen-rich soils in caves (Zeller 1966;Ajello et al 1977;Larcher et al 2003), suggests a convergence of characters in species belonging to different lineages (Nováková and Kolařik 2010).…”

Isolations of onygenalean fungi were made recently from different dung samples from Italy. A striking snowwhite species with gymnothecial ascomata, developed in damp chamber on dormouse dung collected in a cave, was subjected to keratinolytic tests and morphological, cultural, and phylogenetic studies. The keratinolytic ability of this species, associated with a Chrysosporium anamorph and a sexual state of appendiculate reticuloperidia and oblate ascospores, allows it to be accomodated in Onygenaceae. White ascomata, blunt or subcapitate peridial appendages, pitted ascospores, and tuberculate conidia suggest it to be a new Neogymnomyces, and this was confirmed by parsimony analyses of LSU and ITS nrDNA sequences. Following recent phylogenetic analyses, the morphological and physiological features of order Onygenales and its families are re– examined and discussed. After the introduction of a new species, Neogymnomyces is reviewed and compared with all other genera in Onygenaceae. The Chrysosporium imperfect state of Neogymnomyces virgineus is described and compared to the anamorph of N. demonbreunii. It is also compared to the atypical Chrysosporium merdarium and to several other Chrysosporium species with echinulate to verrucose–tuberculate conidia, isolated from guano, dung, and nitrogen–rich soils in caves. The onygenalean fungi isolated from any kind of dung are discussed and their facultative coprophily ascribed to variable faecal contents of keratin or other degradable substances. A key to the families and genera of the Onygenales is provided

“…Although H. capsulatum was once isolated from soil sampled from a cave in Israel, 12 autochthonous cases of histoplasmosis have not been reported in this country. We herein describe a series of 23 imported cases of proven/probable histoplasmosis in Israeli travelers returning from endemic areas.…”
