Description: Thallus crustose, thinly episubstratic, ecorticate, pale grey, spreading, without a distinct prothallus, somehow resembling the thallus of Lepra albescens. Conidiomata sporodochial, superficial, orbicular, white, excavate to flat, 0.2-0.5 mm across, the tissue hyaline, cellular throughout, the cells with 2–4 µm wide lumina. Conidiophores not evident. Conidia globose to slightly ellipsoid, unicellular, hyaline, smooth, the wall relatively thick (c. 0.5 µm), 4-5.5 mm wide. Photobiont chlorococcoid, the cells 5-15 µm wide. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a recently-described species growing on isolated trees with base-rich or -enriched bark in Xanthorion-communities. The species differs considerably from other congeneric species in conidiogenesis, the form of conidia, and the ecology, and according to Muggia & al. (2017), it likely does not belong to Cheiromycina s. str. The species is known from Central Europe, but it could be present also in Italy, and should be looked for there.
