Spores dark purple brown, 7 – 8 (9) x 4 – 6 micrometers, occasionally oddly shaped (more rounded), thin walled, inequilateral, ellipsoid to mango shaped with a germ pore. Cheilocystida abundant forming a sterile band, lageniform often with a thin neck (2 micrometers), sometimes forked. Pleurocystida hard to measure length, maybe 15 – 20 × 6, utriform with a thin short neck. Lamellar trama parallel, 4 micrometers wide. Pileus trama cells form an irregular snakeskin-like pattern, 10 – 20 micrometers across.

Microscopically somewhat close to P. angustipleurocystidia, but this collection has forked cheilocystidia.
