Puttea margaritella (Hulting) S. Stenroos & Huhtinen

A minute boreal lichen specifically associated with the liverwort Ptilidium pulcherrimum, usually growing on its dying stems. In some specimens, there is no obvious contact with the liverwort and older populations may probably grow independently. It usually occurs on dump coniferous wood (lying trunks, cut surfaces of stumps) and tree bases covered with liverworts in humid boreal forests (such as peaty or humid relic pine forests, waterlogged or montane spruce forests). Recently, the species has been recorded in the Šumava, Jeseníky and Beskydy Mts. Older published records of Biatora symmictella from the Žďárské vrchy Hills and Králický Sněžník Mts by F. Kovář (Kovář 1906, 1911) probably refer to P. margaritella due to the reported association with liverworts.
