Ophiostoma babimostense and Sporothrix europaea (Ascomycota, Ophiostomatales), two new ophiostomatalean species, associated with ambrosia and bark beetles in Norway and Poland
The order Ophiostomatales includes many species important for forestry, causing plant diseases. They are common associates of bark- and wood-dwelling beetles. Two new ophiostomatalean fungi viz. Ophiostoma babimostense sp. nov. and Sporothrix europaea sp. nov. are proposed, based on morphological characters and multigene phylogenies. Ophiostoma babimostense belongs to the Ophiostoma ulmi species complex and was isolated from fallen shoots of Scots pine pruned by Tomicus species in Poland. The fungus is characterised by the production of a typical pesotum-like and sporothrix-like asexual morphs. Sporothrix europaea belongs to the Sporothrix gossypina complex and was isolated from hardwood-infested by ambrosia and bark beetles in Poland and Norway. It is characterised by the occurrence of both a sexual and asexual morphs, with long necked ascomata bearing ostiolar hyphae and a sporothrix-like asexual morph.
