Pseudocyphellaria dasyphyllidia – a new phyllidiate species from Chile (Lobariaceae, lichenised Ascomycota)

Pseudocyphellaria dasyphyllidia growing on rocks and trees in rather dry habitats in Chile is described as new to science. It is characterised by a cyanobacterial photobiont, narrow, laciniate and imbricate lobes with hirsute margins, and simple to coralloid, densely hirsute phyllidia that are both marginal and laminai. It is most closely related to the non-phyllidiate species P. hirsuta and P. guillemini.
