Abstract

The following new lichen species are described from the Atlantic rain forest remnant Pedra Talhada (Alagoas, Brazil): Hafellia nortetrapla, with four ascospores per asci, ascospores grey to brown, 1-septate, 30–38 × 13–16 µm, and norstictic acid as secondary chemistry, and Pterygiopsis densisidiata, with an appressed thallus, densely covered with branched isidia, and clearly clustering with species inside the core group of the order Lichinomycetes, as shown by analysis of mtSSU region sequences. A further 19 species are reported as new to Brazil, and 307 new to the state of Alagoas. In total, 442 species have been identified thus far in our collections from Pedra Talhada, and a list of the species is provided.
