Bulbothrix thomasiana

Bulbothrix thomasiana is a species of foliose lichen in the family Parmeliaceae. It is a corticolous species that grows on tree trunks in the northern and central parts of South America. The lichen was formally described as a new species in 2011 by lichenologists Michel Benatti and Marcelo Marcelli. The specific epithet honours American lichenologist Thomas Hawkes Nash III. The species is distinguished by its unusual vegetative structures (isidia), which are uniquely fringed with tiny hair-like projections. It has been found growing on tree bark in tropical forests across northern South America, from Venezuela and French Guiana to central Brazil and Bolivia....read more on Wikipedia.
