Abstract
Previous studies have identified a close relationship between the monospecific Masonhalea richardsonii and Tuckermannopsis inermis. However, formal taxonomic changes were postponed until existing sequence data could be confirmed. Here we validate these data and discuss the transfer of T. inermis to Masonhalea (made by Lumbsch et al. in Thell & Moberg 2011), consider the morphological, anatomical and biogeographic similarities and differences between these two taxa. The two Masonhalea species both produce lateral apothecia, marginal pycnidia, a layer of cortical tissue beneath the pycnidial wall and bacillariform conidia.
