Vienna, 23rd district, Maurer Wald, MTB 7863/4, on basidiomes of Eichleriella deglubens on Populus tremula, 8 Oct. 2009, H. Voglmayr, WU 29538. Notes: Hypocrea austriaca appears to be Ku-0059436 supplier specifically associated with the heterobasidiomycete Eichleriella deglubens. The latter occurs typically on Populus tremula in eastern Austria; basidiomes are usually sterile at the time of infection and stroma development. In the occurrence on a heterobasidiomycete and in morphology H. austriaca is similar to H. sulphurea, which differs in a more intense, deep yellow colour when fresh and by slightly larger ascospores Fedratinib concentration from H. austriaca. Growth of H. austriaca on PDA is substantially slower than that of H. sulphurea or H. citrina. Hypocrea fungicola f. raduli was edited as a part of an exsiccatum by Rehm (1905). No description apart from collection data and

the presumed host Radulum kmetii Bres. was given. The latter is now considered a synonym of Eichleriella deglubens (Berk. & Broome) Lloyd. Two parts of Höhnel’s specimen (from M and FH) were examined. They agree with recently collected material, except for some large aberrant ascospores. The basidiomycetous host is not apparent in the part in M. Phylogenetically the closest relative of H. austriaca is the morphologically similar Australian H. victoriensis. No fungal host of the latter has been detected Cyclooxygenase (COX) yet. Hypocrea citrina (Pers. : Fr.) Fr., Summa Veg. Scand.: 383 (1849). Fig. 56 Fig. 56 Teleomorph of Hypocrea citrina. a–f.
