This work provides new information about five interesting and uncommon hypogeous fungi from Greece – Balsamia vulgaris, Geopora clausa, Hydnocystis piligera, Sclerogaster compactus and Wakefieldia macrospora. Descriptions of the five species are included based upon Greek collections, accompanied by colour macro- and microphotographs, and molecular data of four of them. On the basis of molecular results, the genus Wakefieldia seems to be closely related to Hebeloma in the Hymenogastraceae, while Geopora clausa appears to be related to Geopora in the Pyronemataceae.
