A new species of lignicolous Hyphomycetes, Hyphodiscosia europaea Hol.-Jech. et Borowska, collected on decaying wood and bark in Czechoslovakia and Poland is described and illustrated. Taxonomical investigations of the microfungi inhabiting bark and wood of decaying trunks and stumps in Czechoslovakia and Poland have revealed the presence of one undescribed species of dematiaceous Hyphomycetes which is classified here in Hyphodiscosia Lodha et Chandra Reddy. This genus was recently described (Lodha and Chandra Reddy 1974) as monotypic with H. jaipurensis Lodha et Chandra Reddy, growing on bark of dead wood collected near Jaipur in Rajasthan (India). The characteristic features of Hyphodiscosia are polyblastic conidiogenous cells producing subcylindrical, dorsiventral and 1-septate conidia with two lateral appendages (setulae), arising on the ventral side of the conidium. The species found differs from H. jaipurensis in having 1–3 septate conidia, with a seta on the apical end and a second one in the middle of the ventral side of the basal cell of the conidium. A further difference is in the conidiophores; their conidiogenous parts proliferate successively and sympodially and do not terminate in a swollen conidiogenous apex as in H. jaipurensis. These differences are sufficient to separate this fungus as a new species for which the name Hyphodiscosia europaea is proposed.
