Usnea florida is a species of beard lichen in the family Parmeliaceae. It was first described by Carl Linnaeus in his 1753 work Species Plantarum. German botanist Friedrich Heinrich Wiggers transferred it to the genus Usnea in 1780. It is considered a threatened or vulnerable species in several European countries. [2]
The lichen was first formally described in 1885 by Swiss botanist Johannes Müller Argoviensis as Bottaria cruentata. [4] Richard Harris transferred it to the genus Pyrenula in 1987. [5] In northern North America, where its distribution in the United States is limited to southern Florida, it is commonly known as the bark rash lichen.
Usnea is a genus of fruticose lichens in the large family Parmeliaceae. The genus, which currently contains roughly 130 species, was established by Michel Adanson in 1763. Species in the genus grow like leafless mini-shrubs or tassels anchored on bark or twigs. Members of the genus are commonly called old man's beard, beard lichen, or beard moss.

Usnea filipendula – one of about 20,000 described species of lichen. The following outline provides an overview of and topical guide to lichens.. Lichen – composite organism made up of multiple species – a fungal partner, one or more photosynthetic partners, which can be either green algae or cyanobacteria, and, in at least 52 genera of lichens, a yeast.

Lichen morphology describes the external appearance and structures of a lichen. These can vary considerably from species to species. These can vary considerably from species to species. Lichen growth forms are used to group lichens by "vegetative" thallus types, and forms of "non-vegetative" reproductive parts.
It seems everyone is getting sick. Sniffles. Coughing. Sore throat. And worse.
