Currently, about 90 species are included in
this genus (http://www.indexfungorum.org/, check details 12/01/2009). Phylogenetic study Herpotrichia diffusa (Schwein.) Ellis & Everh., H. juniperi (Duby) Petr., H. herpotrichoides and H. macrotricha have been shown to have phylogenetic affinity with the generic types of Byssosphaeria Apoptosis Compound Library concentration schiedermayeriana, Melanomma pulvis-pyrius and Pleomassaria siparia, which had been assigned under Melanommataceae (Kruys et al. 2006; Mugambi and Huhndorf 2009b; Schoch et al. 2006, 2009; Zhang et al. 2009a). In this study, Pleomassaria siparia together with its closely related species of Prosthemium is kept in a separate family, viz Pleomassariaceae. Concluding remarks Even species under Herpotrichia sensu stricto (according to Sivanesan 1984) have diverse hosts (such as gymnosperms (H. coulteri (Peck) S.K. Bose and H. parasitica (R. Hartig) Rostr.) and angiosperms (H. diffusa and H. villosa Samuels & E. Müll.)) or substrates (like dead or living leaves, bark or decorticated wood) (Sivanesan 1984).
Species of Herpotrichia sensu stricto are also reported from various CA3 manufacturer locations such as Europe, Asia or America, and they have various life styles, e.g. parasitic, hyperparasitic or saprobic (Sivanesan 1984). Additional factors (like hosts or locations) may need to be considered in order to get a natural concept for Herpotrichia. ADAMTS5 Immotthia M.E. Barr, Mycotaxon 29: 504 (1987). (Teichosporaceae) Generic description Habitat terrestrial, hyperparasitic. Ascomata gregarious, globose, superficial, ostiolate, periphysate. Hamathecium of cellular pseudoparaphyses.
