Bilimbia microcarpa (Th. Fr.) Th. Fr.

A green-grey crustose lichen forming subtle brown fruiting bodies. It is a miniature of the related B. sabuletorum, from which it differs in smaller fruiting bodies and shorter, mostly 3-septate ascospores. Although it is an accepted species, still it may be an extreme form of the species B. subuletorum. It grows on moss thalli over various substrates (basic stones and rocks, dead wood, perhaps even over nutrient rich tree bark). It has recently been reported from the Šumava Mts, the Beskydy Mts, the Český kras karst area and from the Hrubý Jeseník Mts. Still, some authors consider it an arctic-alpine lichen with the optimum above the upper timber line (such as Nimis et al. 2018).
