Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive of a specific species and can therefore be used in identification of the species.
It produces only one kind of binucleate spores called the smut pores which are comparable to the teleutospores of rusts. The teleutospores are developed from the terminal cells of the mycelium. Smut spores are formed from the intercalary cells. The teleutospores are stalked, two celled and each cell is binuclate.
