Scutula

Scutula is a genus of lichenicolous fungi in the family Ramalinaceae.

==Taxonomy== The genus Scutula was circumscribed by French botanist Louis René Étienne Tulasne in 1862. The limits of the generic circumscription as well as the limits of certain species in Scutula was confused for a long time. In 1997, Triebel and colleagues applied the name Scutula specifically to a group of species growing on hosts of the Lecanorales suborder Peltigerineae, a monophyletic grouping of cyanobacteria-associated lichens. Before this, Scutula was applied to a diverse set of unrelated lichenicolous fungi featuring hyaline spores with a single septum and sessile apothecia.
