Notes: Among the species with upright stromata in Europe Hypocrea nybergiana forms the largest and darkest stromata. This species is characterized by an unusual combination of traits found in different clades of Hypocrea/Trichoderma. Although H. nybergiana phylogenetically belongs to the pachybasium core group, the inhomogeneous selleck chemicals llc distribution of the cortical pigment is mainly found in teleomorphs of Trichoderma sect. Trichoderma. However, in contrast to that section the cortical cells are distinct, and inflated cells line the ostiolar apex. The anamorph is primitive, unusual for Trichoderma, and at most Carnitine palmitoyltransferase II somehow similar to anamorphs of sect. Hypocreanum. The conidia are variable in shape, reminiscent of those of H. protopulvinata. Hypocrea seppoi Jaklitsch, Karstenia 48: 5 (2008b). Fig. 34 Fig. 34 Hypocrea seppoi. a–k. Teleomorph. a. Dry stroma. b.
