Reck, Mateus A. & Rosa Mara Borges da Silveira. Grammothele species from southern Brazil. Mycotaxon 109: 361–372. 2009.

ABSTRACT:  Three species of Grammothele found in Rio Grande do Sul State in southern Brazil — G. fuligo, G. lineata, G. subargentea — are described and illustrated. Grammothele fuligo is recorded for the first time from extra-Amazonian Brazil. The genus produces resupinate basidiomata with bluish-gray to dark-gray pore surfaces and with very shallow pores; microscopically, it is diagnosed by a dimitic hyphal system, clamped generative hyphae, dextrinoid skeletal hyphae, and abundant dendrohyphidia.
