Abstract
During the past several years, numerous specimens of the Myxophyceae from Indiana, Kentucky and Ohio have accumulated in the herbaria cited below. Some of these species presumably have not previously been reported for this region and are now placed on record.
It is known that many collections of algea, the bases for previous reports, have been lost or are inaccessible. It is the desire of the writer and of other students of the herbarium that all published works on the algae be based only upon permanently preserved specimens.
