Abstract
Two new fungal genera are described from leaves of Dasylirion, a member of the Agavaceae. Comminutispora is set apart by a combination of ascomatal features and its polysporous asci. The new genus and species Hyphospora agavaciensis is established for the anamorph of Comminutispora agavaciensis. Reproduction by means of endoconidia, not blastoconidia, distinguishes Hyphospora from related taxa.
