In order to integrate ustilaginomycetous anamorphs into the general phylogenetic system of
Ustilaginomycetes, partial nuclear large subunit ribosomal DNA sequences of 56
teleomorphic and 19 anamorphic species of the Ustilaginomycetes were analysed.
Maximum parsimony and neighbour joining confirm the new suprageneric system of
Ustilaginomycetes and indicate that (i) the species of Pseudozyma represent anamorphs of
Ustilaginales parasitizing grasses,(ii) Pseudozyma prolifica, the type of Pseudozyma, is very …
