Sphaerosporithyrium is similar with Paratubakia (Braun et al. 2018) in conidial shape and colour. However, the formation of pycnothyria formed by species of the latter genus differs in pointed tips of hyphal scutellum strands. Sphaerosporithyrium is characterized by hyaline globose-subglobose conidia (Braun et al. 2018).
