Observation 302921: Phlebiopsis crassa (Lév.) D. Floudas & Hibbett

Notes:
Growing on a Quercus (?) stick. (Pseudo)dimitic. “Skeletal” hyphae thicker and leading into long, thick-walled cystidia with acute apices. Clamp connections absent. All parts inamyloid. Basidia 4-spored, 21.2 × 5.0 µm (1 measured). Sterigmata ~1.4 µm long (1 measured). Spores smooth. Spores were difficult to find. Spore measurements from Piximetre: 7 – 7.08 (7.1) × (3.9) 3.91 – 4.08 (4.1) µm, Q = (1.7) 1.73 – 1.8; N = 2, Me = 7.1 × 4 µm; Qe = 1.8
Individual spores: 7.04 × 4.08 µm, 7.08 × 3.91 µm
