In the period 2001-2004, several hundreds of undergroundshelters (mainlyab and onedgalleries, caves, and cellars)inW and SWBohemia(CzechRepublic) were explored for insectcadavers with visi­ blefungalgrowth. At27localities, 94infectedcadavers of sixinsecttaxa were collected.Themostfre­ quentinfectedinsects were 7Yiphosadubitata, Scoliopteryxlibatrix(Lepidoptera;Geometridae and Noctuidae, resp.) and unidentifedmosquitoes(Diptera, Culicidae). On the collectedcadavers, alto­ ge the r20 species of microfungi(includingsterilemycelia) were recorded, most of them belonging to entomopathogens. The most frequent was Paecilomyces farinosus (36 % of all samples) and Cordycepssp.(15%)whichhadaffinitytoC. tuberculata and C.riverae. Closeassociation with insects was shownbyCordycepssp.( with Triphosadubitata) and Conidiobolusdestruens( with unidentified mosquitoes). On the contrary, Paecilomycesfarinosus was recordedonfivedifferentinsect species . Also several other interesting species were found (e.g. Hirsutella guignardii, Engyodontium cf. parvisporum), probably not yet recorded from the Czech Republic. Microphotographs of some microfungi studied are included.
