Some Myxomycetes from Panama and Costa Rica

Abstract

The Myxomycetes of Panama have been studied by Martin (4, 5). Standley (8) and Weston (9) reported on species found on Barro Colorado Island but did not list species found in other parts of Panama. So far as I am aware there are no published reports on Myxomycetes from Costa Rica. During the summer of 1952 we were able to make additional collections in Panama and Costa Rica and to add several new reports of species in these areas, as well as range extensions of species previously reported. Only a short time was spent in Costa Rica and nearly all of the collecting was done in the eastern part of the Province of Puntarenas, but several interesting forms were found. In addition to our own collections from Costa Rica, we have several collections com? municated by Dr. C. W. Dodge which are also recorded here. The greater portion of the collecting was done in Panama, particu? larly on Barro Colorado Island, located in Gatun Lake in the Canal Zone, which has been set aside by the U. S. Government as the Canal Zone Biological Area. With the exception of the species collected by Dr. Dodge and his associates, all species reported in this paper were collected by Professor G. W. Martin and myself.
