The new name Neosergipea M. Cáceres, Ertz & Aptroot is introduced to replace Sergipea M. Cáceres, Ertz & Aptroot, which is a later homonym of Sergipea Regali, Uesugui & Santos, a genus of fossil pollen. Using the small subunit of the mitochondrial rDNA cistron, we present an updated phylogeny of the Enterographa clade in Roccellaceae which includes the genera Dichosporidium, Enterographa, Erythrodecton, Mazosia, and Neosergipea. While in a previous analysis the relationship between Neosergipea and Dichosporidium was unresolved, our results suggest Neosergipea to be an unsupported sister to Dichosporidium s. lat. The latter potentially represents two distinct genera, differing in ascospore type.
