Two new multispored species from China, Lecanora anhuiensis Li J. Li & Printzen,
sp. nov. and Lecanora pseudojaponica Li J. Li & Printzen, sp. nov. are described and
illustrated here, based on morphological, chemical and molecular evidence. Lecanora
anhuiensis is characterised by an epruinose, yellowish-brown to deep brown apothecial
disc, an epihymenium with fine crystals, an amphithecium with small crystals, 16-spored
asci and the presence of zeorin, in addition to atranorin. Lecanora pseudojaponica is
characterised by an epruinose, red-brown apothecial disc, an epihymenium without crystals, an amphithecium with small crystals, 8 or 16- spored asci and the presence of zeorin and the stictic acid complex, in addition to atranorin. Phylogenetic reconstructions,
based on mtSSU, nrITS and nrLSU suggest that these two species are members of the
Lecanora subfusca group. They are compared with morphologically similar and phylogenetically related species, based on a nrITS dataset. Phylogenetic results show that
the multispored taxa of Lecanora are polyphyletic. The number of ascospores per ascus
appears to be a taxonomic character of minor importance. Detailed descriptions, discussions and figures for the two new species from China and a key for the multispored
species of Lecanora worldwide are provided.
