ABSTRACT
Recent lichenological fieldwork in the Czech Republic resulted in the discovery
of two previously unrecognized entities in the genus Psilolechia which are described below
as new species: the saxicolous P. cretacea and the lignicolous P. torii. Both taxa regularly
produce a hyphomycetous anamorph in the form of erect, elongate conidiogenous cells
on the thallus surface, and both contain unidentified specific secondary metabolites. The
placement of the two new species within the genus is primarily based on morphology and
chemistry. In addition, three barcodes were received for P. cretacea (ITS, mtSSU) and P. torii
(ITS). A key to the five species of Psilolechia currently known from Europe is included.

The study was supported by a long-term research development programme
