Four new species of <i>Cryptothecia</i> (Arthoniaceae, Ascomycota) and <i>Myriostigma</i> (Arthoniaceae, Ascomycota) from China, based on morphology and molecular phylogeny.

ABSTRACT: In this study, morphological and molecular phylogenetic approaches were used to investigate the species diversity of Cryptothecia and Myriostigma from southern China. We found four new species of Cryptothecia and Myriostigma (C.disjecta, C.sorediatum, M.melanovillosa and M.visus-blotch). Cryptotheciadisjecta is distinguished by verrucose pseudisidia that are loosely scattered on the thallus, the upper parts of which are white or have darker dots. Cryptotheciasorediatum is distinguished by I- medulla and thalli having globose soralia. Myriostigmamelanovillosa is distinguished by thalli with black or purple dots and hyaline to pale yellow ascospores (63-71 × 26-33 µm). Myriostigmavisus-blotch is distinguished
