Anamorph: conidiomata pycnothyria, 120-200 µm diam., strongly flattened, opening with radial splits. Upper wall composed of a single layer of dark brown radially arranged brick-like angular cells, many strongly occluded, the outer edge not hyphal in construction. Lower wall apparently absent. Conidiophores absent. Conidiogenous cells ? doliiform, conidiogenesis obscure. Conidia 3.8-4.6 x 1.5-1.8 µm, bacillar, aseptate, hyaline, thin-walled, smooth, usually with two polar guttules, without an epispore or gelatinous sheath.
Teleomorph: not known.
Not assessed; currently known from a single collection but likely to be overlooked.
The genus assignment is definitely one of convenience. It is unlikely to be congeneric, for example, with anamorphs of the Rhytismatales that are also placed in this form-genus.
Superficial on living leaves of Rhododendron ponticum, not parasitic and probably gaining nutrition from cuticular waxes.
