Though the Gamundi & Horak description says “very crowded,” the accompanying image shows averagely spaced gills for Pluetus. They also go on to say that “members of the genus Pluteus are often observed” in the Andean-Patagonian forest and species identification requires microscopy, but P. spegazzinianus is the only Pluteus listed.
