Teliospore germination is described for 28 additional species of smut fungi, most of which were recently collected in Mexico.Germination for most species is reported here for the first time. Included are some rarely collected species, some recently described by the author, and some previously unknown to exist in the New World. Where new records of exotic species for North America are indicated, germination was used to verify diagnoses, even though reported by previous workers in some instances. In demonstrating germination, family and generic affinities for most species were corroborated, although one required generic transfer.
