Colonies epiphytic on leaves appearing as blackened areas. Superficial hyphae dense, brown, septate, brown, with hyphopodia. Sexual morph: Ascomata superficial, dark brown to black, globose to subglobose, verrucous, arise from hyphae, covered with tuberculate projections, ascomatal setae and appendages absent. Peridium thick, comprising two layers, amorphous blackened outer layer and reddish to brown thin cell layer. Hamathecium composing of evanescent paraphyses. Asci 4–8-spored, unitunicate, hyaline, subcylindrical to ovoid or clavate. Ascospores hyaline to brown, ellipsoidal to oblong, aseptate when immature, 1-septum at maturity. Asexual morph: Undetermined (Hansford 1946; Hosagoudar 2003b).
Notes: Hosagoudar (2003b) introduced Armatellaceae to accommodate genera having cylindrical to subcylindrical asci, 1-septum, hyaline to brown ascospores without phialides (Hongsanan et al. 2015a). This family differs from Meliolaceae in having aggregated colonies, stellate hyphopodia, tuberculate projections covering ascomata, aseptate to 1-septum ascospores, and lacking phialides (Hongsanan et al. 2015a). Armatella is the only genus in this family and the placement of Armatellaceae in Meliolales is uncertain due to the lack of molecular data.
Type genus: Armatella Theiss. & Syd., Annls mycol. 13(3/4): 235 (1915)
