First record of the genus Pseudohydnum (Exidiaceae, Auriculariales, Basidiomycota) for Cuba

Background and Aims: The genus Pseudohydnum is characterized by developing gelatinous basidiomas with hydnoid hymenophore, longitudinally divided phragmobasidia, and subglobose to ellipsoid basidiospores. It has a globally broad distribution, although it is not registered for the Cuban mycobiota. The present work aimed to report the presence of the genus Pseudohydnum and particularly P. gelatinosum in Cuba. Methods: The specimens were collected in the Mayabeque province, Cuba. Their morphological characteristics and field data were recorded, followed by deposition in the mycological collection of the HAC herbarium, of the Ecology and Systematics Institute, belonging to the Ministry of Science, Technology and Environment of Cuba. Key results: The genus Pseudohydnum is recorded for the first time in Cuba, represented by P. gelatinosum. Data on the species are provided, as well as macro-and microscopic photos of some of its structures, to compare with other species of the genus. Conclusions: The distribution area of Pseudohydnum gelatinosum is expanded and the importance of continuing to carry out expeditions in places where there are no previous samplings by mycologists is reaffirmed.
