Type speciesClasterosporium caricinum Schwein.

Notes –The asexual morph of Clasterosporium is characterized by dark hypha, brownish conidiophores, cylindrical or spindle-shaped, 3(+)-celled conidia. The sexual morph of Clasterosporium has reported based on a two species in Clasterosphaeria, and later Clasterosphaeria was synonymised under Clasterosporium (Zhang et al. 2016). The genus sexual characters is superficial, globose, dark brown to black, ostiolate ascomata, later collapsing, 8- spored asci and hyaline to subhyaline, fusiform, 3-septate ascospores (Sivanesan 1984, Hosagoudar 2004). However, these genera have to be recollected and sequenced to confirm their placement.
