Bryologist, 74: 154, 1971.
Synonyms: Anaptychia aquila var. stippaea sensu Dalla Torre & Sarnth.; Anaptychia fusca var. stippaea auct.; Anaptychia stippaea (Ach.) Nádv sensu Nádv.; Kurokawia bryorum (Poelt) S.Y. Kondr., Lőkös & Hur
Distribution: N - Frl (Tretiach & Hafellner 2000), Ven (Nascimbene 2003b), TAA (Nascimbene & al. 2022), Lomb (Ravera & al. 2021b), Piem (Nascimbene & al. 2021), VA. C - Sar (ASU 504620 det R. Moberg).
Description: Thallus foliose, heteromerous, dorsiventral, loosely attached. Lobes linear, flattened, smooth, ascending, often overlapping, 0.3-0.7(-1) mm broad and to 7 mm long, often with small (0.1-0.3 mm wide), ascending, mostly marginal adventitious lobules, the upper surface olive-brown to chestnut brown, darker in sun-forms, the lower surface whitish to pale brown, with a few sparse, mostly sparingly branched, pale to brown rhizines. Upper cortex prosoplectenchymatous, of conglutinated, thick-walled, periclinally arranged hyphae, overlain by a transparent layer of similar hyphae; medulla white; lower cortex prosoplectenchymatous lower cortex poorly developed, the hyphae running parallel to the surface. Apothecia not known. Photobiont chlorococcoid. Spot tests: cortex and medulla K- or K+ faintly yellow in the paler parts of thallus, C-, KC- or KC+ yellow, P-, UV-. Chemistry: without lichen substances or with variable amounts of variolaric acid (especially in the cortex) and zeorin.
Note: an arctic-alpine to boreal-montane, probably circumpolar species found amongst mosses and muribund plants on base-rich siliceous substrata in the alpine and subalpine belts.
