Type species: Endoconidioma populi Tsuneda et al., Mycologia 96(5): 1129 (2004)
Notes: Endoconidioma was introduced by Tsuneda et al. (2004) as a monotypic genus in order to accommodate E. populi in Dothideaceae. Endoconidiogenesis in E. populi is similar to the endoconidial hyphomycete Phaeotheca and no coelomycetous taxa have been reported to produce endoconidia. Morphological characters and DNA sequence data showed that Endoconidioma is distinct from the previously established endoconidial genera (Tsuneda et al. 2004). This genus is characterized by subglobose to flask-shaped, entirely closed conidiomata, forming on a black subiculum, a darkly pigmented peridium and locules filled with conidiogenous cells. Endoconidia are formed endogenously and hyaline, unicellular and released by dissolution of the conidiogenous and the peridial cells of the conidioma. Blastic conidia, light to dark brown, mostly two-celled, produced holoblastically from pigmented, undifferentiated hyphae (Tsuneda et al. 2004). In our phylogenetic analysis (family tree) E. populi is clustered in Dothideaceae with 65/100 % bootstrap support.
