Architrypethelium lauropaluanum

Architrypethelium lauropaluanum is a species of crustose lichen-forming fungus in the family Trypetheliaceae. The lichen forms an olive-yellow, crusty patch on tree bark with a distinctively bumpy, wart-like surface. Its reproductive structures are flask-shaped bodies deeply embedded between the raised bumps, and it produces unusually large ascospores that typically have three divisions. The species is found in montane Atlantic rainforest regions of Brazil and has also been recorded from lowland rainforest in Peru....read more on Wikipedia.
