Observation 299521: Schizoporaceae Jülich

Notes:
Growing on the side of a decorticated Quercus alba log with Xylobolus frustulatus and Hymenochaete sp. Fairly soft. All microscopic structures inamyloid. Cystidia thin-walled and not encrusted. Some capitate/subcapitate cystidia present. No astrocystidia present. Monomitic. Some hyphae encrusted and clamped. Spores smooth. Basidia primarily 2-spored but with some 4-spored. Spore measurements from Piximetre: (3.6) 3.7 – 4.4 (4.8) × (3) 3.3 – 3.9 (4.1) µm, Q = 1 – 1.2 (1.3); N = 7, Me = 4.1 × 3.6 µm; Qe = 1.1
Individual spores: 3.77 × 3.02 µm, 4.39 × 3.85 µm, 4.18 × 4.09 µm, 4.75 × 3.79 µm, 3.72 × 3.35 µm, 4.25 × 3.44 µm, 3.60 × 3.60 µm
