Pulvinodecton

Pulvinodecton is a genus of lichen-forming fungi in the family Roccellaceae. It has two species.[1] The genus was circumscribed in 1998 by lichenologists Aino Henssen and Göran Thor, with Pulvinodecton kurzii assigned as the type species. Pulvinodecton differs from Erythrodecton in having spindle-shaped (fusiform) rather than doubly club-shaped (biclavate) ascospores, and by the development of its ascocarp. Additionally, the unusual pycnidia of Pulvinodecton species feature a deeply divided cavity with more than one ostiole.[2]
