Thallus immersed in the substratum or thin, scattered-granular or rimose-areolate, whitish grey to brownish grey, epruinose. Soredia absent. Prothallus not visible. Apothecia sessile to slightly constricted at the base, 0.5–1.0 mm diam.; disc yellowish brown to olivaceous brown or pale yellowish to greenish grey, epruinose or slightly grey-pruinose; margin whitish grey, ±whitish-pruinose, thin to thick, entire to verrucose. Cortex hyaline, distinct, gelatinous, inspersed with small crystals, 30–60 µm thick. Amphithecium lacking crystals, densely packed with algae; algal layer continuous below hymenium. Parathecium hyaline, lacking crystals. Epihymenium yellowish brown to red-brown, c. 10 µm thick, with numerous small crystals insoluble in KOH. Hymenium and subhymenium hyaline. Hypothecium hyaline to yellowish brown. Paraphyses sparingly branched and thickened apically. Ascospores ellipsoidal, 8.0–12.5 × 5.5–7.0 µm. CHEMISTRY: Thallus and apothecial margin K– or K+ yellowish, C–, Pd–; containing vinetorin (major) and 5,7-dichloro-3-O-methylnorlichexanthone (minor). | ||
A species on exposed limestone or nutrient-rich, siliceous rocks in pasture and coastal habitats in S.A., N.S.W. and Tas.; also on Heard Is. The distribution of L. flotowiana is poorly known since it was often misidentified as L. dispersa. Probably a pantemperate lichen. | ||
