Japewiella
Introduction '''''Japewiella''''' is a genus of lichen in the family Lecanoraceae. It was circumscribed in 2000 by German botanist and lichenologist Christian Printzen as a segregate of the genus ''Japewia''. The genus name of ''Japewia'' was in honour of Peter Wilfrid James (1930 - 2014), who was an English botanist (Mycology and Lichenology). The genus was circumscribed by Christian Printzen in Bryologist vol.102 on page 715 in 1999.The type, ''Japewiella carrollii'', is an oceanic species that occurs in maritime regions of Europe and Macaronesia.
Description ''Japewiella'' species are crust lichens that grow on bark. They are characterized by their biatorine apothecia, thick-walled, simple ascospores, eight-spored asci with a conspicuous ''masse axiale'' (similar to asci found in members of genus ''Lecidella''). They have a well-developed excipulum (a saucer-shaped rim around the hymenium) comprising branched and anastomosing, gelatinized hyphae.
