Based on the phylogenetic analyses of a combined LSU, ITS and tef1 dataset in Plectosphaerellaceae and the morphological difference from Synnemellisia and other Plectosphaerellaceae genera, Longitudinalis was established by Tibpromma et al. (2018) for a taxon L. nabanheensis (Giraldo & Crous 2019, Index Fungorum 2020, NCBI 2019). The genus is characterized by synnemata with yellow-green to dark-brown stem and a dark-brown pin-like head of conidiogenous cells. Conidia are aggregated on a pin-like head, fusoid-ellipsoid, tapering towards both ends, with apex subobtuse to obtuse, at the beginning hyaline with dark brown at the towards both ends and immature conidia yellow-green with brown longitudinal striations (Tibpromma et al. 2018).
Type species: Longitudinalis nabanheensis Tibpromma & K.D. Hyde.
Other accepted species: Species Fungorum – search Longitudinalis.
