Everniopsis is a fungal genus in the family Parmeliaceae. It consists of a single species, [3] the bark-dwelling lichen Everniopsis trulla, which occurs in Africa and South America.
Everniopsis trulla was first formally described by Erik Acharius in 1803 with the name Parmelia trulla. [4] The type material, collected in Peru, is kept at the herbarium of the Department of Botany at the Swedish Museum of Natural History. [5] William Nylander transferred the taxon to the new genus Everniopsis in 1860. [6] Ernst Stizenberger thought that Everniopsis should be a section of genus Parmelia, and proposed this classification in an 1862 publication. [7] The genus Hendrickxia, circumscribed by Belgian botanist Paul Auguste Duvigneaud in 1942 with Hendrickxia pseudoreticulata as the type species, [8] has been folded into synonymy with Everniopsis. [1]
Molecular phylogenetic analysis indicates that Everniopsis is in the Psiloparmelioid clade of the family Parmeliaceae, along with the genus Psiloparmelia. [9] [10]
Evernipiopsis has a thallus attached by a holdfast to its substrate. The lobes comprising the thallus are linearly elongated, split into two at the ends, and longitudinally grooved (canaliculate). The thallus lacks both rhizines (root-like structures) and cilia (short, eyelash-like hair). Its conidia ( asexual spores) are rod-shaped with swellings at each end (bifusiform). It produces ascospores that are ellipsoid in shape, measuring 12–16 by 7–10 μm. [11] The superficially similar genus Everniastrum, in contrast, does not have a holdfast, it does have both rhizines and cilia, and its conidia are cylindrical. [11]
Secondary chemicals that have been identified from Everniopsis trulla include usnic acid, atranorin, and ethyl haematommate. [12]
Everniopsis trulla is a corticolous lichen and occurs in Africa and South America. On the latter continent, the lichen occurs at high elevations from Mexico south to northern Chile. [13]
