Grammothele

Grammothele is a genus of poroid crust fungi in the family Polyporaceae.

Taxonomy
Circumscribed by mycologists Miles Joseph Berkeley and Moses Ashley Curtis in 1868, they considered the genus to combine the characteristics of Hymenogramme and Grandinia. The generic name combines the Ancient Greek words γραμμή ("line" or "written character") and θηλή ("nipple").

Grammothele originally contained four species: G. polygramma, G. grisea, G. mappa, and the type, G. lineata. Modern taxonomic opinion now considers the first three of these to be synonymous with the latter.
