Type species: Oblongocollomyces variabilis (F.J.J. Van der Walt, Slippers & G.J. Marais) Tao Yang & Crous, in Yang et al., Fungal Biology 121: 339 (2016).

Sphaeropsis variabilis F.J.J. Van der Walt, Slippers & G.J. Marais, in Slippers et al., Persoonia 33: 164 (2014).

Notes: Oblongocollomyces was introduced by Yang et al. (2017) as a monotypic genus in Botryosphaeriaceae. In earlier studies, this species was identified as Sphaeropsis variabilis and it was different from Sphaeropsis in having long conidiomatal necks on PNA, aggregated in dense clusters of conidiomata on OA (Yang et al. 2017). This species has conidia with up to 3 septa. Phylogenetically Oblongocollomyces close to Alanphillipsia (Fig. 14).

Fig. 14 Phylogram generated from maximum likelihood analysis (RAxML) of Botryosphaeriales based on ITS and LSU sequence data. Maximum likelihood bootstrap values equal to or greater than 70%, Bayesian posterior probabilities equal to or greater than 0.90 (MLBS/PP) are given at the nodes. Isolate numbers are noted after each species name. The tree is rooted to Patellaria quercus (CPC 27232 and BHI F828a). Newly sequence data generated in this study are in blue. Ex-type and references strains are indicated in bold. Hyphen (-) represents support values less than 70% MLBS and 0.90 PP
