Durrieu & Zambett., (1973) Microbotryum violaceum, also known as the anther smut fungus, was formerly known as Ustilago violacea.

But it has now separated into many species due to its host specificity.

Meiosis in M. violaceum produces a tetrad of four haploid meiotic products.

Pairwise intra-tetrad mating can occur between these meiotic products.
