Type: Hypocrella_discoidea (Berk. & Broome) Sacc. Description: Sexual morph: Stromata generally pulvinate, with or without hypothallus, in various shades of whitish, yellow, orange, and green, stroma surface generally minutely pulverulent or pruinose; stromatic tissue generally changing colour in 3% KOH, to reddish or brown. Perithecia generally embedded in stroma or half-embedded, stroma outer tissue of textura epidermoidea, cell walls ca 0.5–3 µm thick; stroma internal tissue generally of textura intricata, cell walls generally thin, 0.5–3.5 µm. Perithecia obpyriform to sub-globose. Asci mostly cylindrical or clavate, µm, generally capitate. Ascospores hyaline, multi-septate, smooth, filiform to long fusiform, non-disarticulating. Asexual morph: Conidiomata from original substrata pycnidial generally flask-shaped, phialides formed in a thick compact palisade, in short conidiophores sometimes indistinct, branching once monochasial, twice monochasial, monoverticillate, or two level monochasial, phialides cylindrical, slightly tapering towards tip. Conidial masses mucilaginous; conidia hyaline, smooth, unicellular, fusoid, generally with acute ends. Paraphyses generally present. Host: Scale insects and whiteflies.
