Huriella flakusii (Teloschistaceae, lichenized Ascomycota), a new species from the Colca Canyon region in Peru

A new species, Huriella flakusii, is described from the arid region of the Colca Canyon in southern Peru, and is characterized by squamulose, orange thalli and abundant, crowded and aggregated, usually flexuous when compressed, reddish apothecia. The thalline cortex, proper margin and hypothecium are paraplectenchymatous. The ascospores are broadly ellipsoid, 10.15 x 5.0.9.5 mu m, with rather thin septa, 2.4 mu m. Phylogenetic analyses of the DNA sequences of ITS, nuLSU and mrSSU rDNA markers revealed that the new species is nested within the Amundsenia-Squamulea subclade in the subfamily Xanthorioideae, and has a sister group relationship to Huriella loekoesiana from South Korea.
