Lichinella granulosa

Ciri dan struktur

The thallus is blackish and dull to slightly glossy, forming spreading, irregularly crusts or small, roundish to irregular squamules with minutely margins and a finely granular center. Individual areoles or squamules are about 0.4–1(–1.4) mm wide, and attach by tufts of arising from the main thallus hyphae. Internally the thallus is , with robust fungal hyphae forming a dense network around large unicellular cyanobacterial cells that have thick, yellowish-brown gelatinous sheaths (the sheath reacting K+). Fruiting bodies are thallinocarpous and small (about 0.15–0.4(–0.5) mm wide), initially semi-immersed to and sometimes becoming stipitate. The is black and remains unchanged when moistened, with a thin but persistent (though indistinct) and no . The hymenium is hyaline and covered by small packets of thalline tissue, giving an IKI+ (blue) reaction that rapidly turns reddish-brown. Asci are thin-walled and typically 16–24(–32)-spored, and the ascospores are , hyaline, broadly ellipsoid, about 5–7 × 3–4 μm. Pycnidia are immersed, producing small ellipsoid conidia about 3–3.5 × 1 μm, and no lichen substances were detected. Spot tests are reported to be negative, and no secondary metabolites were detected.

Habitat dan peran ekologis

Lichinella granulosa grows on a range of rock types, including limestone, caliche, rhyolite, sandstone, and granite, and has been recorded from roughly 500 to 1750 m elevation. It occurs in desert to woodland settings, including lower Colorado and upland Sonoran Desert habitats, dry Chihuahuan Desert habitats, and pine-oak woodlands. In the Greater Sonoran Desert flora, the species is described as "very common" in Arizona but easy to overlook or misidentify, especially when sterile, when it can resemble a non-fruiting member of the Lichinaceae. When fertile, the thallus becomes more irregular in outline and the surface granules tend to proliferate. Thin sections can help confirm the thallinocarpous fruiting bodies and the characteristic thallus anatomy with large photobiont cells surrounded by short-celled hyphae. The species tends to favor seepage tracks and bare rock surfaces on inclined boulders that are often north-facing, where periodic water flow appears to create suitable microsites for establishment and persistence. As treated by Schultz, the known distribution was based on more than 30 collections from central, southern, and southeastern Arizona, with additional records from southern California, southern New Mexico, northwestern Texas, and Sinaloa in Mexico.
