Microscopic notes:
- Basidia are both 2- and 4-spored, mostly 4-spored
- Spores 13.69 μm long (right near midpoint of range for P. cyanesens [12-15(17) μm long])
- Fruitbody stained dark but likely was initially pale coloured “whitish, yellowish, isabelline”
- likely since this is the most common species in subgen Copelandia
- medium thickness yellow-brown metuloids (more so than cambodginiensis, less so than tropicalis)

Many unknown highly refractive cells found on gill face (refractive in the way Sulphidia are refractive, however these are distinctly angular/rectangular), possibly a foreign contaminant but maybe worth documenting either way?
