Ciri dan struktur
Saprobic on a dead leaf of Musa sp. Sexual morph Undetermined. Asexual morph Hyphomycetous. Sporodochia dark, dense, dry, powdery, velvety, 1–2 mm diameter. Conidiophore mother cells 3.4–5.8 × 3.7–4.7 μm (x̄ = 4.6 × 4.1 μm, n = 10) subhyaline or light brown, doliiform or subspherical. Conidiophores usually short to long bearing two types of conidia referred to here as α and β. Conidiophores of α conidia up to 40–85 × 0.8–2.5 μm (x̄ = 64 × 21.7 μm, n = 15), pale brown or dark golden brown, rough-walled, hyaline at bottom near the conidiophore mother cell, pale brown at middle, dark golden brown at top near conidial cells, erect or flexuous, narrow and long, generally unbranched, rarely branched. Conidiophores of β conidia 0.7–3.5 × 1.5–3 μm (x̄ = 1.9 × 2.3 μm, n = 15) short, erect, unbranched, hyaline when immature, subhyaline or hyaline at maturity. Conidiogenous cell development basauxic, forming a single, terminal holoblastic conidium at the apex of conidiophore. Conidial development holoblastic. Conidia solitary, dry, two types: α conidia stellate, 15–22.7 × 14.5–20.5 μm (x̄ = 18.8 × 17.8 μm, n = 15), 4–6 celled, each cell globose to subglobose, deeply constricted at the septa, conspicuously spinulate, 4–6 spines, each 2–8 μm long arise from surface of each cell. β conidia disc-shaped, initially hyaline, 4-celled, each cell slightly turbinate in shape, rough-walled, crossed septate, becoming brown to dark brown at maturity, each cell turbinate, crossed-septate, smooth-walled, light brown at the center near the septa, dark brown at periphery in constricted areas, 9.3–14.2 × 8.4–12.5 μm (x̄ = 12.7 × 10.8 μm, n = 40), somewhat obovoid, deeply constricted at the septa, flat from side view, frequently with attached conidiogenous cells when splitting from the conidiophores.
