The shape of the surface hairs decides the affiliation to the genus. Since species with branched as well as with unbranched surface hairs are comprised in the genus Henningsomyces O. K., s. 1., I should like to suggest to divide this genus into two more homogeneous genera. Accordingly species with branched surface hairs would be adjoined to the genus Henningsomyces O. K., s. str., whereas species with unbranched surface hairs would be assigned to a new genus Rectipilus Agerer.
