Aggregatorygma triseptatum

About

Aggregatorygma triseptatum is a species of lichen in the family Graphidaceae. First described in 2014 from collections near Porto Velho in Rondônia, it forms pale gray-green patches on tree bark with distinctive star-shaped clusters of narrow fruiting bodies. The species is characterized by extremely small spores with three cross-walls and two unidentified secondary metabolites. It grows in the shaded understory of undisturbed Amazon rainforest and has since been recorded in several Brazilian states.
