Megalotremis is a genus of lichen-forming fungi in the family Monoblastiaceae. It has 16 species. The genus was circumscribed by Dutch lichenologist André Aptroot in 1991, with Megalotremis verrucosa assigned as the type species. Megalotremis is a genus, meaning its species have ascocarps: spherical or flask-shaped, sessile or partly immersed in the thallus, with a single opening (ostiole) and enclosed by a distinct wall.

Clypeopyrenis is a genus of lichen-forming fungi in the family Pyrenulaceae. The genus was circumscribed in 1991 by Dutch lichenologist André Aptroot, with Clypeopyrenis microsperma assigned as the type species. This lichen, originally described from material collected in Costa Rica, is also found in the Caribbean and South America. Clypeopyrenis porinoides was added to the genus in 2011; it was discovered in Costa Rica, close to the type locality of the type species.

Aciculopsora is a small genus of lichen-forming fungi in the family Ramalinaceae. The genus was established in 2006 and as of 2025 contains three recognised species, all found growing on tree bark in tropical regions. These lichens are distributed across Central and South America, East Africa, and Sri Lanka, though they appear to be rare or simply under-collected.

Septotrapelia is a genus of lichen-forming fungi in the family Ectolechiaceae. It comprises four species. Species in this genus form tiny, scale-like crusts on rocks and are distinguished by their chocolate-brown fruiting discs with pale margins and unusually large ascospores divided into three segments. These small, bluish-grey lichens grow primarily on volcanic boulders and weathered stone in tropical and subtropical regions, from Costa Rica and the Galápagos to Thailand and South Korea. The genus was established in 2007 after DNA studies showed that certain species with this distinctive spo

Parapyrenis is a genus of fungi in the family Pyrenulaceae.
