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