Etymology – derived from the genus name Acervuloseptoria.
Diagnosis – difers from the genus Acervuloseptoria by its pycnidial conidiomata opening via central ostioles and intermingled among spermatogonia.
Description – (adapted from Crous et al. 2020): plant pathogenic, foliicolous. Conidiomata pycnidial, intermingled among spermatogonia, black, opening via ostiole; wall brown, textura angularis. Conidiophores reduced to conidiogenous cells lining the inner cavity. Conidiogenous cells subcylindrical to ampulliform, hyaline, smooth, proliferating percurrently and sympodially at apex. Conidia solitary, subcylindrical, hyaline, smooth, granular, straight to curved, apex subobtuse, base truncate with basal marginal frill, septate.
Type species – Neoacervuloseptoria fraxini (Crous & Bulgakov) Raghv. Singh & Sanjay (≡ Acervuloseptoria fraxini Crous & Bulgakov).
Figure 1 – Phylogenetic tree resulting from a RAxML analysis of the combined LSU/RPB2/ITS sequence alignment (dataset 2). The Bayesian posterior probabilities (≥0.90; BI-PP), maximum likelihood bootstrap support values (≥50%; ML-BS) and maximum parsimony bootstrap support values (≥50%; MP-BS) are given at the nodes (BI-PP/ML-BS/MP-BS). The newly introduced lineage is represented in bold and novel genera denoted in blue. The family name Mycosphaerellaceae is unabbreviated, while others are abbreviated as follows: D=Dissoconiaceae, P=Phaeothecoidiellaceae, S=Schizothyriaceae, T=Teratosphaeriaceae, C=Cladosporiaceae. The tree is rooted to Cylindroseptoria ceratoniae (CBS 477.69).
