Neoramularia U. Braun, Nova Hedwigia 53: 291 (1991).

Index Fungorum number: IF 11285; Facesoffungi number: FoF 08630, 10 morphological species (Species Fungorum 2022), no molecular data available.

Associated with leaf spot. Sexual morph: Unknown. Asexual morph: Mycelium consisting of hyaline or subhyaline, septate, branched, thin-walled hyphae forming stromata or not. Conidiophores macronematous, usually in large fascicles, sometimes forming sporodochial and basistromatic conidiomata, emerging through stomata or erumpent through the cuticle, straight, subcylindrical to geniculate-sinuous, simple, hyaline or faintly pigmented, continuous or septate, thin-walled, smooth or occasionally rough. Conidiogenous cells integrated, terminal, polyblastic, percurrent and sympodial, conidiogenous loci inconspicuous, not thickened or darkened. Conidia solitary or catenate, ellipsoid-ovoid, subcylindrical or fusoid, hyaline or slightly pigmented, aseptate to 3- septate, thin-walled, smooth or almost so, hila unthickened and hyaline, conidial secession schizolytic (adapted from Videira et al. 2017).


Type species: Neoramularia eurotiae (Gamalizk.) U. Braun


Notes: Neoramularia is characterised by macronematous conidiophores, polyblastic, percurrent and sympodial conidiogenous cells and ellipsoid-ovoid, subcylindrical or fusoid, hyaline or slightly pigmented conidia. Neoramularia resembles Ramularia but differs in having unthickened and not darkened conidiogenous loci and conidial hila, while in Ramularia loci and hila are lacking. The placement of Neoramularia in Mycosphaerellaceae is doubtful. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of the genus.
