Sarcogyne

Sarcogyne is a genus of crustose lichen-forming fungi in the family Acarosporaceae. It was circumscribed by German botanist Julius von Flotow in 1850. A proposal has been put forth in 2021 to assign Sarcogyne clavus as the type species of the genus, "as it represents the original concept of Sarcogyne as having melanized apothecia without algae in the margin".

==Description== Genus Sarcogyne includes lichens with a crust-like (crustose) thallus that can be cracked into small, island-like sections called , which are either broadly attached or have a thick fungal base. Sometimes, the thallus is , meaning it has small, scale-like structures with a stalk less than half the width of the scale.
