An expedition to the Dominican Republic to survey discomycetes was conducted in January 2002. In this expedition, 111 discomycete samples were collected: 22 Pezizales, 81 Helotiales, 6 Ostropales and 2 Rhytismatales. This field trip added 39 new reports for the Dominican Republic. To date, 79 species of discomycetes are known in the Dominican Republic in the following orders: 34 Pezizales, 42 Helotiales, 2 Ostropales and 1 Rhytismatales. The great majority (87%) of these species are our new reports for the Dominican Republic and about 38% are new for the Greater Antilles and the Caribbean region. Most of the species of discomycetes known in the Dominican Republic are of tropical origin. Some of the reports are discomycete species from north temperate regions: Morchella, Gyromitra, Helvella, Pseudoplectania nigrella, Plectania melastoma, Leotia viscose, Podophacidium xanthomelum and Lachnum virgineum. Based on our work from Dominican Republic, we can conservatively predict 20% of the material collected should represent new records and new taxa.
