Usnea lambii is a small species of fruticose lichen in the family Parmeliaceae. [2] It was first formally described as a new species in 1954 by Henry Imshaug.It has a bipolar distribution, that is, it occurs at both of Earth's polar regions.
The Lecideaceae are a family of lichen-forming fungi in the order Lecideales.It contains about 30 genera and roughly 250 species.A major distinguishing characteristic of the family is the lecanoroid form of the fruiting bodies: typically circular, dark, and without a thalline margin.
Peltigera praetextata, or the scaly dog pelt lichen, is a foliose lichen native to North America, Europe, and Asia. [1] It is defined by small belly-button-like growths called phyllidia on its edges and centre.
But sometimes the parts of a lichen species common name are common names of other lichen genera. For example, Psilolechia lucida, in the genus Psilolechia, is commonly called "sulphur dust lichen". [1] [2] But "sulphur lichen" refers to the genus Fulgensia, and "dust lichen" refers either to the genus Chrysothrix or the genus Lepraria. [1] [3 ...
Unlike green algal lichens, where photobionts typically form distinct evolutionary lineages adapted to lichen symbiosis, cyanolichen photobionts are more closely related to free-living cyanobacteria. Rather than forming tightly co-evolving partnerships, cyanobacterial symbionts in cyanolichens are often recruited from environmental populations ...
Parmelia pinnatifida is a species of foliose lichen in the family Parmeliaceae, first recognised as a distinct species in 1976.Originally classified as a variety of P. omphalodes in 1803, it is characterised by its small, circular body with narrow, highly branched, overlapping lobes, and its grey to brown upper surface contrasting with a black underside.
The genus name Tuckermannopsis honours Edward Tuckerman (1817–1886), who was an American botanist and professor who made significant contributions to the study of lichens and other alpine plants. He was a founding member of the Natural History Society of Boston and most of his career was spent at Amherst College .
Cetraria laevigata is a species of ground-dwelling, fruticose (bushy) lichen in the family Parmeliaceae. It was formally described as a new species by Russian lichenologist Kseniya Aleksandrovna Rassadina in 1943. In North America, it is commonly known as the striped Iceland lichen. [1]
