Abstract
Two new species of Pyxidiophora (Ascomycota, Laboulbeniomycetes, Pyxidiophorales) associated with bark beetles (Coleoptera, Scolytidae) colonising the sapwood and secondary phloem of conifers (Larix decidua and Picea abies) in Europe are described. Each of both fungal species appeared to be connected with a Gabarnaudia-like anamorph. Pyxidiophora corallisetosa could only be cultivated in the presence of the hyphomycete Clonostachys rosea, and a connection of P. corallisetosa with its Gabarnaudia-like anamorph was proven by the development of perithecia after axenic transfer of conidia to cultures of C. rosea. Pyxidiophora cuniculicola was found in cultures originating from bark beetles placed onto agar media. Conidia developing directly from germinating ascospores were identical to those developing from Gabarnaudia-like conidiophores also present in these cultures, which indicates an anamorph-teleomorph connection. The probable interactions between both species of Pyxidiophora with associated fungi are discussed.
