'''''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.<ref name="Tulasne 1852"/> The limits of the generic circumscription as well as the limits of certain species in ''Scutula'' was confused for a long time.<ref name="Santesson 1960"/><ref name="Hawksworth 1986"/><ref name="Hawksworth 2000"/><ref name="Hawksworth 2003"/> 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.<ref name="Triebel et al. 1997"/> Before this, ''Scutula'' was applied to a diverse set of unrelated lichenicolous fungi featuring hyaline spores with a single septum and sessile apothecia.<ref name="Wedin et al. 2007"/>

Once classified in the family Micareaceae, molecular phylogenetic analysis showed ''Scutula'' to be nested within the Ramalinaceae, closely related to the genus ''Toninia''.<ref name="Andersen & Ekman 2005"/> This familial placement has been accepted in recent large-scale updates of fungal classifications.<ref name="Lücking et al. 2017"/><ref name="Wijayawardene et al. 2017"/><ref name="Wijayawardene et al. 2020"/>

==Description== ''Scutula'' species are characterized by apothecia that are either lecideine (where exciple forms the underside and outer layer of the apothecium, extending up to the rim, where it forms a darkened "proper margin") or biatorine (having a pale, not darkened proper margin and always lacking a thalline margin). The paraphyses are non-capitate (i.e., lacking a knob-like structure at the tip). Asci have a fuzzy amyloid (in Lugol's iodine solution after pre-treatment with KOH) axial tube structure of the ‘Scutula’-type. The ascospores are smooth, hyaline, and contain a single septum. Anamorphs associated with ''Scutula'' include ''Libertiella'' in the mesoconidia and ''Karsteniomyces'' in the macroconidia.<ref name="Wedin et al. 2007"/>
