Index Fungorum Number: Faceoffungi Number:
Sexual morph: saprobic, ascomata: 250-400 µm in diam., globose, superficial, nonostiolate, cleistothecial, membranaceous, white to orange, or pale brown, gregarious. Peridium: thin, transparent, pseudoparenchymatous, composed of several layers of angular or rounded cells, smooth, dissolving irregularly at maturity. Paraphyses: absent. Asci: 44-50 x 30-40 µm, 8-spored, globose or subglobose, sessile, unitunicate, thin-walled, aphysoclastic, without apical apparatuses, scattered irregularly in the venter of ascomata, deliquescing at spore maturity. Ascospores: 18-21 x 10-13 µm, ellipsoidal or ovoidal, 1-septate in the middle, not constricted at the septum, smooth or slightly rough, thick-walled, hyaline. Asexual morph: Conidiophores: 20-28 x 3-4 mm, mostly unbranched, erect, developing from aerial hyphae. Conidia: 8-12 x 3-4 µm, ellipsoidal, hyaline, originating as blown-out ends of the conidiophores and accumulating in the loose clusters; imperfect state of the Trichothecium type (Description: Based on Tubaki (1967)).
