Vizellopsis was introduced by Batista et al. (1969) with the type species V. grevilleae. This monotypic genus was formally placed in the family Microthyriaceae based on the black, circular, flattened thyriothecia. Vizellopsis is morphologically similar to Asterina by orbicular thyriothecia opening by star-like fissure, superficial hyphae. However, it differs from Asterina by hyphae lacking appressoria, septate, branched pseudoparaphyses and broad fusiform to long obovoid, pale brown ascospores (Fig. 1). The asexual morph of this genus has not been recorded (Dai et al. 2014). Dai et al. (2014) and Hongsanan et al. (2014a) placed Vizellopsis in Asterinaceae based on its small, blackened, orbicular thyriothecia comprising radiating cells with superficial dark brown mycelia. However, we suggest to transfer this genus in Asterinales incertae sedis based on its distinct morphology until it is confirmed with molecular data.
