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 37A degrees 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.
