Seventy taxa of dematiaceous Hyphomycetes belonging to 44 genera were collected in the Province Pinar del Rio, in the western part of Cuba. An attention was mainly given to the saprophytic microfungi colonizing dead wood and bark of different broad-leaved trees, palms and decaying herbaceous material. Twenty-three hyphomycetes are recorded here for the first time from the Cuban territory, seven taxa of them are described and illustrated as new for science: Corynesporopsis rionensis Hol.-Jech., Monodictys sessilis Hol.-Jech., Pithomyces sumiderensis Hol.-Jech., Pseudospiropes cubensis Hol.-Jech., Sporidesmium dissolvens Hol.-Jech., Mercado et Mena, Virgariella caribensis Hol.-Jech., as new species and Sporidesmium tropicale M. B. Ellis var. cubensis Hol.-Jech. as a new variety. Codinaea lunulospora Hewings et Crane is transferred to Dictyochaeta and Sporidesmium pseudolmediae Castañeda to Corynespora. One typical lignicolous ascomycete Nitschkia acanthostroma (Mont.) Nannfeldt is also added.
