Bryoria
Bryoria is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens.[2] The genus has a widespread distribution, especially in boreal and cool temperate areas.
Bryoria was circumscribed in 1977 by lichenologists Irwin Brodo and David Hawksworth, with Bryoria trichodes as the type species.[3]
Bryoria species are fruticose, slender and hair-like, tending to grow hanging (pendent) or like a small bush. They range in colour from dark brown to pale greyish brown to grey in some species. Ascospores are colourless, ellipsoid, numbering eight per ascus.[4]
Other hair-like lichens that may be confused with Bryoria include dark brown species of Bryocaulon, Nodobryoria, Pseudephebe, Alectoria, or Cetraria.[4]
Found almost exclusively on conifers, or on tundra soil,[4] Bryoria collectively has a widespread distribution, especially in boreal and cool temperate areas.[5]
