bavarica, H. moravica, H. pachybasioides

and H. parapilulifera. These species form either green or white pustulate Trichoderma anamorphs, while H. bavarica and H. pachypallida produce their hyaline conidia in verticillium-like effuse conidiation. Hypocrea bavarica AZD8931 mw differs from H. pachypallida in a different ecology, i.e. a distinct affinity to Betula, typically appearing on bark early after the death of branches, a conspicuous and fast colour change upon selleck products drying, a pseudoparenchymatous subcortical tissue, slightly smaller ascospores, predominantly subglobose to oval conidia, an unpleasant odour on PDA, and a substantially slower growth. H. moravica differs from H. pachypallida also in considerably larger ostiolar dots, H. argillacea differs in larger ascospores. The Swedish specimen of H. pachypallida is

somewhat untypical due to more intense yellow colours and larger ostiolar dots. ITS and rpb2 sequences of the six isolates are identical, while there is considerable variation in tef1 sequences, which may eventually lead to a recognition of two species. However, differences may possibly AICAR in vitro be caused by technical issues rather than a true genetic difference. Hypocrea parapilulifera B.S. Lu, Druzhin. & Samuels, Mycologia 96: 331 (2004).
