Lecidea tessellata is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecideaceae.[3] It was formally described as a species in 1819 by German botanist Heinrich Flörke.
Description
Lecidea tessellata has a chalky white to grey, cracked and areolate thallus. Its apothecia are black, subimmersed, appressed to adnate and range from 0.5 to 1.8 (–2.0) mm in diameter. The apothecial [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is smooth, initially rounded in young apothecia, but becomes convex and irregular in mature ones, sometimes with a thin white pruinose layer. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is brownish-green to blackish-green and the [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is colorless, measuring 40–60 μm in height. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is pale brown and measures 30–40 μm in height, while the [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is blackish-green externally and colorless internally. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] are clavate and measure 30–50 by 8–14 μm, and the ascospores are ellipsoid and measure 7–9 by 5–6 μm. Lecidea tessellata contains confluentic acid, a lichen product that can be detected using thin-layer chromatography. Both the thallus and medulla of the lichen have negative reactions with standard chemical spot tests (K−, C−, PD−).[4]
Lecidea oreophila, found in the mountains of California's Sierra Nevada, is similar in appearance to L. tessellata, but it has a dark hypothecium and produces 2′-O-methylmicrophyllinic acid as the primary lichen product, with or without accessory confluentic acid.[5]
Habitat and distribution
In northern North America, it is common and widely distributed, growing on non-calcareous rocks.[6] It also occurs in Afghanistan, China, Nepal, Europe, and Russian Asia. In India, it has been recorded only from the alpine Western Himalayas at an altitude of 3,450 m (11,320 ft).[4] In Nepal, Lecidea tessellata has been reported from 5,080 to 5,639 m elevation in a compilation of published records; this reported range lies above the tree line used in the study.[7] Its southern distribution extends to James Ross Island, where it is locally common.[8]
