Sexual morph: Ascomata superficial, globose to subglobose, verrucose. Peridium thick, comprising black, verrucose outer stratum, and brown inner stratum of textura angularis.

Type genusArmatella 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.
