Constrictolumina

Constrictolumina is a genus of lichen-forming fungi in the family Trypetheliaceae. The genus was circumscribed in 2016 by Robert Lücking, Matthew Nelsen, and André Aptroot, with Constrictolumina cinchonae assigned as the type species. The genus contains tropical species, formerly placed in genus Arthopyrenia, with a unique hamathecium.
