This taxon was described from lowland Costa Rican material only a few years ago. One population has been discovered at montane elevations near Jardin de Dota that agree with the type material. Collybia lodgeae possesses an overall morphotype that is mimicked by many related Collybias. To wit: thin-fleshed pilei with brown pigmentation at first, durable texture, distant lamellae, growth on litter or wood, striate to twisted-striate stipes, and, probably most importantly, sulcate pilei. Other possible suspects might include: C. subpruinosa, C. polygramma, or G. neotropicus. The taxon illustrated however, has huge pleurocystidia; they'll push the oculars of your microscope right back into your eyes.
