Trypetheliopsis

Trypetheliopsis is a genus of lichen-forming fungi in the family Monoblastiaceae. It contains eight species. The genus grows as a thin crust on tree bark, typically in tropical and subtropical regions, and is recognised by its flask-shaped fruiting bodies that are embedded within raised, crusty structures on the lichen's surface. Species in this genus were largely forgotten by lichenologists for several decades until 2009, when researchers studying Japanese herbarium specimens "resurrected" the group by reclassifying several related lichens within it.
