Ciri dan struktur
Xanthocarpia tominii is a crustose lichen with a thallus that is usually egg-yellow to orange-yellow, but may also appear brownish, light yellow, or greenish-orange. It is made up of small, rounded s that may be scattered or fused into a larger crust. These areoles are usually convex and only slightly lobed. The larger ones, before they become , can be somewhat shield-shaped, while the smaller ones are attached directly by hyphae. Lobes are usually absent, although older specimens may develop small marginal lobes. There is no distinct . The thallus produces abundant soredia, usually along the raised margins of the areoles and sometimes across their upper surface as well, giving older parts a more powdery appearance. Apothecia (fruiting bodies), when present, are very rare, small, and flat, with a dull orange to reddish-brown that may darken with age, and a thick margin that is often also sorediate. The internal tissues include a thin , a continuous , and a dense medulla. The thallus gives a red reaction with potassium hydroxide solution (K).
Habitat dan peran ekologis
In North America, Xanthocarpia tominii grows on soil rather than rock, occurring on both calcareous and non-calcareous substrates in dry, open habitats. It is found chiefly in western North America and Arctic localities including Greenland, and has been recorded in southwestern Yukon on loess deposits in open Artemisia steppe. The species is adapted to dry, exposed, base-rich sites in regions with a strongly continental climate, which helps explain its occurrence in semi-desert habitats. Its usual growth on soil helps distinguish it from the more rock-inhabiting Flavoplaca citrina.
