Mostly biotrophic on monocotyledons and dicotyledons (except Poaceae). Sexual morph: Stroma of various shapes, covered by a cuticular or epidermal shiny blackened clypeus, with limited development around the ostiole or extensively above the ascomata and sometimes below the ascomata. Pseudostroma strongly developed, interfusing and conspicuously expanding into the host tissue. Ascomata perithecial, amphigenous, epiphyllous or hyphophyllous, uni-to multiloculate, sometimes confluent, frequently surrounded by a bright yellow to reddish coloured zone, subcuticular, epidermal, subepidermal or immersed in the host tissue, pyriform, globose, lenticular, or deformed by vascular bundles, with a periphysate ostiole. Peridium hyaline to pigmented, composed of cells of textura intricata. Paraphyses hyaline, thin-walled, slightly longer than the asci, septate, often dissolving during maturation. Asci 8-spored, rarely 4-spored, unitunicate, clavate or cylindrical, usually, apical ring often J-. Ascospores 1–2-seriate, usually hyaline, rarely pale brown, globose to filiform, mostly cylindrical, thin and smooth-walled, aseptate to 3-septate, sometimes surrounded mucilaginous sheath. Spermatogonia infrequently found, pycnidial, spermatiogenous cells cylindrical, tapering towards the tip, proliferating percurrently, with filiform, hyaline, aseptate scolecospores, probably spermatial in function. Asexual morph: Undetermined (adapted from Mardones et al. 2017).
Notes – Mardones et al. (2017) redefined Phyllachoraceae and proposed the new family Telimenaceae with Telimena erythrinae as the type species, resulting in three families in Phyllachorales. Telimena species occur on monocotyledons and eudicotyledons, except Poaceae, and generally have enlarged black pseudostroma around the perithecia (Mardones et al. 2017, 2018). Phylogenetic analyses of combined LSU, SSU, ITS, rpb2 and tef1 sequence data showed that Telimena spp. formed a well-separated monophyletic clade in Phyllachorales (Mardones et al. 2017) and this was also found in Dayarathne et al. (2017).
Type genus: Telimena Racib., Parasit. Alg. Pilze Java’s (Jakarta) 1: [18] (1900).
