Morphological variation and taxonomic characters in Cribraria (Myxomycetes) from the Great Smoky Mountains National Park in eastern USA
Adamonyte, Grazina; Eliasson, Uno H.
Cribraria is one of the most taxonomically difficult genera in the myxomycetes. The genus as a whole is well characterized but several of the currently accepted species are vaguely defined with ranges of morphological variation overlapping. Morphological characters are discussed based on specimens of eleven species from the Great Smoky Mountains National Park in eastern U.S.A. Cribraria persoonii, C. piriformis and C. vulgaris are reported from the National Park for the first time, making a total of 21 species of the genus so far recorded in the Park. Other species discussed in some detail include C. elegans, C. intricata, C. languescens, C. macrocarpa and C. oregana. Light photomicrographs illustrate most of the species.
