Index Fungorum: IF820561; Facesoffungi: FoFxxxxx; MycoBank: MB805655.

Pathogenic on living leaf of Aloe ferox. Sexual morph: Unknown. Asexual morph: Conidiomata up to 250 μm diam. (on PNA), pycnidial, solitary, black, erumpent, globose, exuding colourless conidial masses. Peridium up to 40 μm thick, composed of several layers of textura angularis, inner wall of hyaline textura angularis. Ostiole up to 20 μm diam., central. Conidiophores subcylindrical to ampulliform, reduced to conidiogenous cells. Conidiogenous cells 5–13 × 3–4 μm, terminal, subcylindrical, hyaline, smooth, coated in a mucoid layer, proliferating several times percurrently near apex. Conidia (8–)14–18(–27) × (6.5–) 7–8(–9) μm, solitary, hyaline, aseptate, thin and smooth walled, granular, or with a single large central guttule, ellipsoid to obovoid or subcylindrical, tapering towards a narrow truncate base, 3–5 μm diam., enclosed in a thin, persistent mucoid sheath, 1–2 μm thick, and bearing a hyaline, apical mucoid appendage, (7–)15–20(–23) × 2–3(–3.5) μm, flexible, unbranched, tapering towards an acutely rounded tip.

Culture characteristics: Colonies erumpent, spreading, with sparse aerial mycelium and feathery margins, covering the dish in 1 month. On MEA surface olivaceous-grey, reverse iron-grey; on OA and PDA iron-grey on surface and reverse.
