Table 1: _Cont._All species in clade 2, are characterized by a white or brownish lower surface. Clade 2 forms a monophyletic group with strong support for its division from clade 1. Consequently, we propose a new genus, _Pseudosolorina_, to classify this clade. Here, we present three new species and five new combinations for the new genus _Pseudosolorina_. We further subdivide the genus _Pseudosolorina_ into three groups. The first group contains three species, _P. hepatizon, P. simensis_, and _P. tenuior_, which share thallus and apotheium morphological characters and have a single photobiont layer containing both cyanobacteria and chlorophytes. Group 2 contains two species, _P. parmigera_ and _P.
