Index Fungorum number: IF 82149; MycoBank number: MB 82149; Facesoffungi number: FoF 00723; 17 species.
Colonies epiphyllous or hypophyllous, mostly confluent. Hyphae superficial, brown, straight to flexuous, septate, branched, reticulate, with hyphopodia. Hyphopodia alternate to unilateral, mostly 2-celled, brown, with capitates head cells, with irregular lobes, stalk cells rarely septate. Sexual morph: Ascomata superficial, globose to subglobose, verrucose. Peridium thick, comprising black, verrucose outer stratum, and brown inner stratum of textura angularis. Asci 4–8-spored, unitunicate, subcylindrical to ovoid, or clavate, with ascus wall attenuated or broken when mature. Ascospores ellipsoidal to oblong, 1-septate, not constricted at the septum, hyaline when young, becoming brown at maturity. Asexual morph: Undetermined (adapted from Maharachchimbura et al. 2016b).
Type genus – Armatella Theiss. & Syd.
Notes – Armatellaceae was established by Hosagoudar (2003) with 16 species. It differs from Meliolaceae by its 1-septate ascospores, verrucose ascomata and lacking phialides. There is no sequence data for Armatellaceae. The taxonomic placement is supported by morphology.
