Trypetheliopsis kalbii

Trypetheliopsis kalbii is a species of foliicolous (leaf-dwelling) crustose lichen in the family Monoblastiaceae. The species was first described in 1996 as Musaespora kalbii by Robert Lücking and Emmanuël Sérusiaux, and was transferred to Trypetheliopsis in 2009 when that genus was revived to include Musaespora as a synonym. It forms thin, slightly shiny greyish-bronze patches on leaf surfaces, typically 10–30 mm across, and produces small wart-like fruiting bodies along with distinctive hood-shaped structures that release asexual spores. The lichen has a pantropical distribution, recorded from Costa Rica, French Guiana, the West Indies, Madagascar, Papua New Guinea, Guyana, Mexico, and Queensland, Australia. It grows on living leaves in tropical rainforests, favouring semi-open microhabitats such as light gaps and forest edges at elevations from sea level to about 2,500 metres, though most frequently between 500 and 1,500 metres....read more on Wikipedia.
