hyphal system either monomitic or dimitic (generative and binding?) but all thin-walled, clamp connections abundant, somethingorother-hyphidia/-physes maybe also present? i don’t know, crusts are hard; basidia with four-sterigmata; cystidia abundant but not projecting far beyond hymenium (cystidioles? pseudocystidia?), flexuous and of varying lengths, apparently with faint yellow contents/lumen (gleocystidia?); spores hyaline, smooth, weakly amyloid, (best viewed at lower magnifications, refraction/chromatic aberration?) with prominent apiculus, broadly ellipsoid to subglobose.

Collected from my Pogonomyrmex occidentalis colony's setup. I'm guessing they were eating the discarded seeds in the foraging area. I also found these guys in my Camponotus pennsylvanicus colony's setup. I assume they came in on the dubia roaches, since that's the only thing I've fed both colonies that could carry these.

If any other photos are needed for a more accurate ID, let me know.
