Phyllocharis orbicularis

Phyllocharis orbicularis is a leaf-dwelling lichen in the family Strigulaceae. It is the only known species in the fungal genus Phyllocharis. The genus was originally erected by Antoine Fée in 1825; in its modern circumscription its sole species, P. orbicularis, is based on a lichen first described by Elias Magnus Fries in 1830. This leaf-dwelling lichen grows beneath the surface layer of leaves in tropical and subtropical regions, forming pale grey-green patches from lowland to mountain forests. It has a wide pantropical distribution, recorded from the Americas (including Costa Rica, Bolivia, Colombia, Suriname, Argentina, and Florida), as well as from Australia, the Philippines, Vietnam, India, and Kenya. The species is distinguished by its transparent three-celled ascospores and uniquely long, thread-like asexual spores....read more on Wikipedia.
