Strigulaceae is a family of mostly lichen-forming fungi, one of two families in the order Strigulales (class Dothideomycetes). A molecular analysis of the type genus, Strigula, has led to a reallocation of the foliicolous species into six genera that correspond to well-delimited clades with diagnostic phenotype features. These lichens live almost exclusively in tropical rainforests, where they grow as thin films on the surface of living leaves rather than on bark or rock like many other lichens. The family includes around 140 species distributed across multiple continents, making them one of

Peltigera lepidophora, commonly known as the scaly pelt, is a species of foliose lichen in the family Peltigeraceae. It was first described by Finnish lichenologist Edvard August Vainio in 1878 as a variety of Peltigera canina. German botanist Friedrich August Georg Bitter promoted it to species status in 1904. The lichen has a pale to dark brown thallus comprising rounded and concave lobes that measure 5–10 mm (0.2–0.4 in) across. The upper surface is covered with isidia, while the lower surface has pale, indistinct veins and unbranched rhizines. It grows on exposed soil, such as roadsides

Menegazzia cincinnata is a species of foliose lichen from southern South America. It was first scientifically described by Swedish lichenologist Erik Acharius as Parmelia cincinnata. Friedrich August Georg Bitter transferred it to the genus Menegazzia in 1901. Menegazzia cincinnata is quite similar in morphology to Menegazzia valdiviensis, but the two species can be distinguished from each other by a combination of ascospore length and the presence or absence of thamnolic acid in the medulla.

Menegazzia foraminulosa is a species of corticolous (bark-dwelling), foliose lichen that is endemic to New Zealand. The lichen was first formally described as a new species in 1876 by August von Krempelhuber. Friedrich Bitter transferred it to the genus Menegazzia in 1901. The species contains several lichen products, including depsides (atranorin and chloroatranorin), depsidones (stictic acid, constictic acid, norstictic acid, and menegazziaic acids), as well as fatty acids and pigments.
