Pseudopyrenula hexamera is a species of bark-dwelling, crustose lichen in the family Trypetheliaceae.[1] It is distinguished within its genus by having five-septate spores, a unique feature among Pseudopyrenula species. The species is known only from Venezuela, where it was collected in lowland Amazonian rainforest.
The species was formally described from a type specimen collected on the west bank of the Surumoni River, near Esmeralda in the Alto Orinoco region of Amazonas state, Venezuela, at an elevation of 110 m (360 ft). The specimen was found on the bark of a tree in the genus Qualea. It is the only member of Pseudopyrenula with consistently five-septate ascospores. While it resembles Polymeridium quinqueseptatum, it differs by the thickened walls of its spores, which give rise to the diamond-shaped internal cavities (lumina) typical of Pseudopyrenula.[2]
