Contribución al catálogo de los Gasteromycetes (Basidiomycotina, Fungi) de Costa Rica

This paper presents a revision of 819 herbarium collections of Gasteromycetes from Costa Rica. One hundred and three taxa were identified, two of them are new records for America: Cyathus africanus and Morganella compacta; and 44 are new to Costa Rica: Bovista aestivalis, B. cunninghamii, B. dermoxantha, B. dominicensis, B. longispora, Calostoma lutescens, C. ravenelii, Calvatia candida, C. excipuliformis, Chlamydopus meyenianus, Crucibulum laeve, Cyathus earlei, C. berkeleyanus, C. helenae, C. julietae, C. limbatus, C. montagnei, C. nova-zealandiae, C. pallidus, C. poeppigii, C. setosus, Geastrum badium, G. fimbriatum, G. fimbriatum var. pseudohieronimii var. nov., G. javanicum, G. lageniforme, G. minimum, G. rufescens, G. smardae, G. striatum, Langermannia bicolor, L. gigantea, Lycogalopsis solmsii, Lycoperdon echinatum, L. eximium, L. juruense, Phallogaster saccatus, Scleroderma bovista, S. cepa, S. verrucosum, Vascellum endotephrum, V. floridanum,V. pratense and V. texense. Five genera are new to Costa Rica: Chlamydopus, Langermannia, Lycogalopsis, Phallogaster and Vascellum. Comments related with their taxonomy, ecology and distribution are also included. Based on the results, we conclude that the Gasteromycetes flora of Costa Rica is one of the richest in America, if we take into account the small area of the country. Richness may be due to more intensive sampling than in other neotropical countries, as well as to a range of altitudes from sea level to 3820 m.
