Micarea pseudolignaria

Micarea pseudolignaria is a species of lichen-forming fungus in the family Ectolechiaceae. It was described as new to science in 2014 from the tropical island of Réunion (Mascarene archipelago) in the Indian Ocean. The type collection was made in the Forêt de Bébour, on the path from Bélouve to Cabane Dufour, where it grew on soil in wet montane ericoid ericoid (heather-family) thickets at about 1,740 m elevation, overgrowing decaying bryophytes. The lichen forms a small, greyish-green body (thallus), about 2 cm across, with a cracked surface of slightly domed patches (areoles, about 0.2–0.3 mm wide). It lacks a distinct outer skin (cortex), though parts of the surface are covered by a thin, clear dead layer (an epinecral layer). Its fruiting bodies (apothecia) are shiny black, convex, up to about 0.6 mm wide, and often merge to form compound structures. The ascospores are oval (ellipsoid), usually 2-celled (1-septate), and measure about 8.0–9.2 × 3.0–3.3 μm. Chemically, it contains an......read more on Wikipedia.
