S. granulosa S. gymnopiperis S. penicillata S. rubropenicillata Sprucidea is a genus of four crustose lichens in the family Malmideaceae.

[1] Similar to the related genus Malmidea, Sprucidea is characterized by frequently red thalli that contain the secondary compound norsolorinic acid, but differs in the rod-shaped instead of ellipsoid ascospores and in the stalked sporodochia as conidiomata.

Sprucidea species are found in rainforest areas in South America and Southeast Asia.

S. granulosa and the type species, S. rubropenicillata, were described as new to science, while S. gymnopiperis and S. penicillata were two proposed new combinations from the genera Malmidea and Bacidina, respectively.

[2] The genus name of Sprucidea is in honour of Richard Spruce (1817–1893), who was an English botanist specializing in bryology.
