Type species – Clasterosporium 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 been reported based on two species in Clasterosphaeria, and later Clasterosphaeria was synonymised under Clasterosporium (Zhang et al. 2016). The genus sexual characters are 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.
