Gregorella humida is a species of cyanolichen in the family Arctomiaceae that grows on disturbed soils.[1] It is a granular crust-like thallus that varies in color from various forms of grey to dark brown.[1][2]
Taxonomy
Gregorella humida was first described in Finland in 1871 as Biatora humida. Later on, the species was transferred, based on its morphology, to Moelleropsis humida under the family Pannariaceae.[1] It was only in 2002 that the species' molecular data was published and showed that it was not related to the species type of Moelleropsis, M. nebulosa, or the family Pannariaceae. It was found to be closely related to Arctomia and Wawea and finally transferred to the monotypic genus Gregorella.[2]
Distribution
The species has been collected from soils in Oregon, United States to the Eurasian continent, specifically Fennoscandia, the United Kingdom, Continental Europe, and Turkey.[1] Types of soils the lichen species have been found in include sandy, loamy, disturbed, and bare soil.[1][2]
Description
Scientists describe Gregorella humida as ranging from blue, brown, or olive greys to dark brown.[1][2] With the naked eye, the lichen species can be described as having a minuscule granular, crust-like thallus. However, under the microscope, the species grows in a branch-like pattern and contains cyanobacteria.[1]
