Type species – Endoconidioma populi Tsuneda, Hambl. & Currah, Mycologia 96(5): 1129 (2004).
Notes – Endoconidioma was introduced as a monotypic genus to accommodate E. populi in Dothideaceae. Endoconidioma populi is a melanized taxon belonging to black meristematic fungal group which are cosmopolitan and easily adaptable to extreme environmental conditions (Mirzaei et al. 2015, Wanasinghe et al. 2018c). Endoconidioma rosae-hissaricae was introduced by Wanasinghe et al. (2018c). Morphologically, E. populi has two-celled conidia while they are aseptate in E. rosaehissaricae (Wanasinghe et al. 2018c). This genus is characterized by subglobose to flask-shaped and entirely closed conidiomata, which forms on a black subiculum, a darkly pigmented peridium and locules filled with conidiogenous cells (Thambugala et al. 2014a, Wanasinghe et al. 2018c). Endoconidia are formed endogenously and are hyaline, unicellular and released by dissolution of the conidiogenous and the peridial cells of the conidiomata. Blastic conidia, mostly two-celled, light to dark brown are produced holoblastically from pigmented, undifferentiated hyphae (Tsuneda et al. 2004, Thambugala et al. 2014a). In our phylogenetic analysis, Endoconidioma grouped within Dothideaceae (Fig. 1).

Figure 1 – Phylogram generated from maximum likelihood analysis (RAxML) of Dothideales based on ITS, LSU and SSU sequence data. Maximum likelihood bootstrap values equal or above 70 %, Bayesian posterior probabilities equal or above 0.90 (MLBS/PP) are given at the nodes. An original isolate number is noted after the species name. The tree is rooted to Elsinoe phaseoli (CBS 165.3), E. veneta (AFTOL-ID 1853), Myriangium duriaei (AFTOL-ID 1304), and M. hispanicum (CBS 247.33). The ex-type strains are indicated in bold. Hyphen (-) represents support values below 70 % MLBS and 0.90 PP.
