The crustose thallus of Caloplaca kedrovopadensis is thin, continuous to cracked, and greenish-yellow in colour. It has many apothecia (spore-bearing structures), which measure 0.3–0.55 mm in diameter. Its asci can hold eight spores, but they often instead have 1, 2, 4, or sometimes 6 of the mature, bipolar spores. These ascospores are spindle-shaped (fusiform) with tapered ends, split into two cells by a central septum (hence, "bipolar"), and measure 19–26 by 8.5–10 μm.[1]
Habitat and distribution
Caloplaca kedrovopadensis was first recorded from the Kedrovaya Pad Nature Reserve in Russia, and a few years later, from the Jiri Mountain of South Korea, at an altitude of 1,314 m (4,311 ft). Both of the Korean collections were found growing on bark.[2][3]Phaeophyscia exornatula, Verrucaria species, and Aspicilia species are other lichens that have been noted to grow in close association with Caloplaca kedrovopadensis.[1]
