Pseudolachnella brevifusiformis A. Hashim. & Kaz. Tanaka, in Li et al., Fungal Diversity 78:  (2016)
Facesoffungi number: FoF 02029
Saprobic on dead sheath of Pleioblastus linearis. Sexual morph undetermined. Asexual morph Conidiomata 230–900 µm diam., 170–350 µm high, stromatic, solitary or gregarious, initially conical, then subcupulate, subglobose to oval, unilocular, dark brown to black, setose. Conidiomatal setae up to 100 µm long, numerous, restricted to the margin of the conidiomata, at first incurved over the conidial hymenium, then divergent, cylindrical, straight or slightly curved, unbranched, aseptate, pale brown to dark brown, thick-walled, acute and narrowed at apex. Conidiomatal wall 10–35 µm wide, composed of thick-walled, brown cells of textura intricata to textura epidermoidea. Conidiophores 7.5–14 × 1.6–14 µm, formed from inner layers of the conidiomata, hyaline, cylindrical to subcylindrical, broader at base, branched, smooth-walled. Conidiogenous cells 7–2 × 2–4 µm, hyaline, enteroblastic, phialidic, cylindrical to lageniform, with periclinal thickening in the collarette zone, indeterminate, usually integrated, thick- and smooth-walled. Conidia 3–15 × 3–4.5 µm ( = 12 × 4 µm; n = 30), hyaline, circular or cylindrical, rounded at apex, truncate and narrow at base, 0–3-septate, straight, guttulate, smooth, bearing appendages at both ends; apical appendage 3–6 µm long, 2–6-unbranched, flexuous, centric or excentric, arising from the top of the apical cell or adjacent to apical cell, basal appendage 3–6 µm long, 2–4-unbranched.
