Index Fungorum Number – IF 811035; Facesoffungi Number: FoF 01796

Parasitic in larva of Coleoptera (Superfamily Tenebrionoidea), forming yellow to orange ascostromata. Sexual morph: Ascomycetous. Stromata 14 mm long, 2-5 mm wide, growing from the head and the tail of Coleoptera larva, simple or branched, yellow to orange, stipitate. Stipe 1.9–3.7 cm long, 2–4 cm wide, yellow, cylindrical, surface rough. Fertile head 30 mm long, 2–2.5 mm wide, orange, mostly elliptic barely branched, head-like, with orange, pseudoparenchymatous, epidermal tissues, surface mastoid, differentiated from stipe. Ascomata 453–546 × 265–298 μm (x̄ = 479 × 270, n = 30), completely immersed, orange, flask-shaped to oval, with the ostioles opening on the surface of the head. Peridium 26–38 μm wide (x̄ = 30, n = 60), comprising three layers. Asci 366–498× 8–11 μm (x̄ = 437 × 10, n = 60), 8-spored, hyaline, cylindrical, with apical cap, breaking into secondly ascospores. Secondary ascospores 2–6 × 1–3 μm (x̄ = 4 × 2, n = 60), hyaline, cylindrical. Asexual morph: Undetermined. (Adopted from Li et al. 2016)

Known hosts and distribution: on dead larva of Tenebrionoidea (China) (Li et al. 2016)

Moelecular data: MFLU 15-3888 (SSU = KU854951, RPB1 = KU854947, TEF = KU854949). Phylogenetic tree: see entry (Ophiocordyceps karstii) (Li et al. 2016)
