Ciri dan struktur
Gloeoheppia turgida has a (scaly) thallus made up of small, leaf-like . These are round to elongate and , sometimes overlapping, and become strongly convex and swollen, reaching up to about 4 mm across. Their margins curve downwards and are often rolled under, and the thallus is anchored to the substrate by coarse fungal hyphae. The thallus lacks a and is attached by rhizoidal strands, and its hyphae form a network around a small, single-celled cyanobiont. The upper surface is smooth and dark olive to greenish black, becoming paler in shaded situations, and may carry a thin white, powdery deposit (a ); it is covered by a relatively thick layer of dead tissue. The underside is smooth, olive to pale flesh-coloured and lacks a differentiated cortex. The medulla contains an that extends through most, or sometimes all, of its depth. Where a lower algal-free zone is present it consists of tightly packed, fungal cells. Vegetative propagules such as isidia and soredia have not been reported. Sexual reproduction occurs in immersed apothecia (fruiting bodies) produced one to many per squamule; the exposed are dark brown to blackish and typically about 0.2–0.8 mm across, and the hymenium and stain deep blue in iodine. The asci usually contain eight spores, but 10–12-spored asci have also been observed, and the colourless, ellipsoid ascospores measure about 10–14 by 6–8 μm. Physiological measurements on thalli collected in the Judean Desert found that humid air alone did not activate positive net photosynthesis; instead, the lichen required wetting with liquid water. Immediately after spraying, net photosynthesis remained low (under 20% of its maximum), which the authors attributed to diffusion limitation in the water-saturated thallus.
Habitat dan peran ekologis
Gloeoheppia turgida has been collected on calcareous soil and rock in the Mediterranean, Macaronesian, and Saharo-Arabian regions. It has also been collected in xeric soil-lichen communities in the Judaean Desert (Israel), on the slopes of the Dead Sea near Ein Boqeq.
