Index Fungorum number: IF110673; Facesoffungi number: FoF 06242

Saprobic on decayed wood with corticeaceous fungus. Sexual morph: Undetermined. Asexual morph: Mycelium mostly immersed. Conidiomata 46–91 µm high × 78–90 µm diam., (x̅ = 71.9 × 82.7 µm, n = 10), superficial, pulvinate, setiferous, dark-brown to black with a basal aggregation of thick-walled, dark brown cells. Setae straight or flexuous, peripheral, arising directly from cells of the basal stroma, subulate, reddish brown to dark brown, septate, thick-walled, smooth, pointed at apex. Conidiophores micronematous, short, cylindrical, pale-brown, unbranched. Conidiogeneous cells holoblastic, monoblastic, integrated, terminal, and determinate. Conidia 68–72 µm × 23–27 µm (x̅ = 70.5 × 26.7 µm, n = 10), acrogenous, solitary, dry, broadly fusoid, truncate at the base, multiseptate,dark-brown, with hyaline to very pale brown terminal cells, thick and smooth-walled.

Material examined – USA, Hawaii, Molokai, Kau, Mt. House trip, on decayed wood with corticeaceous fungus, 9 June 1952, M.L. Lohman s.n. (BISH 594584).

Economic significance – The genus Excipulariopsis seems to be both saprobic and pathogenic as it has also been reported in Cocos nucifera L in India (Dubey & Pandey 2019).
