Colonies epiphytic on leaves appearing as blackened areas. Superficial hyphae dense, brown, septate, brown, with hyphopodia, hyphal setae absent. Hyphopodia brown, irregularly capitate, alternate or opposite, 2-celled. Sexual morph: Ascomata superficial, dark brown to black, globose to sub globose, verrucous, arise from hyphae, covered with tuberculate projections, ascomatal setae and appendages absent. Peridium thick, comprising two layers, outer layer amorphous and black, inner layer thick, comprising reddish to brown cells of textura angularis to globulosa. 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, constricted at the septum, with rounded ends. Asexual morph: Phialides absent (Hansford 1946; Hosagoudar 2003b; Hongsanan et al. 2015a).
Notes: Theissen and Sydow (1915) introduced Armatella, designating the type species as A. litseae and placed in Polystigmellaceae (Hosagoudar 2003b). Hansford (1946) re-examined the type species and transferred it to Meliolaceae. Later, Hosagoudar (2003b) established Armatellaceae to accommodate this genus.
Type species: Armatella litseae (Henn.) Theiss. & Syd., Annls mycol. 13(3/4): 235 (1915)
