Aggregatorygma is a small genus of lichenized fungi in the family Graphidaceae.

[1] It was circumscribed in 2014 by Marcela Cáceres, André Aptroot, and Robert Lücking as a monotypic genus, with Aggregatorygma triseptatum as its only species.

[4][5] The genus name is a combination of two words.

Aggregato is from the Latin word meaning "aggregated",[6] while rygma is from the Ancient Greek word ρήγμα, meaning "crack".

[7] Species in the genus are corticolous, growing on the bark of tree trunks in rainforest.
