Solorina bispora

Ciri dan struktur

Solorina bispora is a small foliose (leaf-like) lichen that forms patches 5–10 mm wide. The thallus (main body) consists of rounded or irregular small surrounded by darker tissue. The upper surface appears pale greyish-green, sometimes with brownish tints, and often has a whitish, powdery coating (). When wet, the surface becomes bright green. The lower surface is white with indistinct veining and scattered pale root-like structures called rhizines. The species produces abundant reproductive structures (apothecia), which are brown to blackish disc-shaped organs partially embedded in the thallus. These measure 2 – 5 mm across and lack a rim of tissue () around their edge. Inside the apothecia, each spore sac (ascus) contains two dark brown spores. The spores are divided into two cells by a central wall (septum) and measure 60–105 by 25–60 micrometres, with a distinctive net-like (reticulation) pattern on their surface. Like other lichens, S. lbispora is a symbiotic organism containing photosynthetic partners: its primary photobiont is a green alga (Coccomyxa), while it also contains colonies of cyanobacteria (Nostoc) in specialised structures called cephalodia. These cephalodia are usually internal and visible as dark spots on the lower surface, though they occasionally develop externally. The species does not produce any unique lichen products and shows no colour changes when tested with common chemical spot tests used in lichen identification.

Habitat dan peran ekologis

Solorina bispora grows predominantly in calcareous environments, particularly in rock crevices and on humus-rich soils. The species has been documented across several European countries, including France, Iceland, Norway, Spain, Sweden, Austria, and Switzerland. It occurs across a wide elevational range, typically from 750 to 2,700 metres above sea level. In North America, S. bispora has been recorded from Alaska, the Arctic, the Pacific Northwest, and the Rocky Mountains. It is uncommon in Ontario. Its circumpolar distribution includes South Greenland and Svalbard. The lichen can be found in various montane and subalpine habitats. In Spain, it has been recorded growing in rock crevices within Pinus nigra and Fagus sylvatica forests. In Sweden, it has been documented in mountain meadows and rock crevices. Specimens have also been collected from calcareous grasslands and on soil among mosses. In Nepal, Solorina bispora has been reported from 3,600 to 4,200 m elevation in a compilation of published records. At lower elevations, it tends to occur in sheltered, north-facing rock crevices within forested areas, while at higher elevations it can be found in more exposed alpine environments.
