RESUPINATE BASIDIOMICETES FROM COSTA-RICA - LITSCHAUERELLA, SUBULICYSTIDIUM AND TUBULICIUM (CORTICIACEAE S.L.)

Eleven species of resupinate basidiomycetes : Litschauerella abietis; Subulicystidium brachysporum, cochleum, longisporum, meridense, navicu latum, perlongisporum; Tubulicium dussii, vermicularis, vermiferum, rh aphidosporum (Boid. & Gilles) Oberw., Kisimova & Gomez, comb.nov., ram onense Oberw., Kisimova & Gomez nov. sp. (Corticiaceae s.l.) are repor ted from Costa Rica. All the species are briefly described and illustr ated. The term ''podoradix'' is coined to describe the rootlike proces ses that anchor the cystidia to the substrate.It is expected that futu re, intensive fieldwork on these fungi will reveal the existence of ma ny more species in Costs Rica, particularly in elevations above 1 500 m.
