Observation 313057: Tulasnella J.Schröt.

Notes:
Growing on a decorticated hardwood log on the bank of a creek in a hardwood forest. All structures inamyloid, Monomitic with simple-septate generative hyphae. Basidia 4-sterigmate with swollen epibasidia. Spores smooth and allantoid. Spore measurements from Piximetre: (2.9) 3.1 – 3.4 × (0.7) 0.8 – 0.9 (1.1) µm, Q = (3.1) 3.2 – 4.1 (4.6); N = 10, Me = 3.2 × 0.9 µm; Qe = 3.7
Individual spores: 3.17 × 0.83 µm, 2.90 × 0.92 µm, 3.07 × 0.87 µm, 3.36 × 0.82 µm, 3.42 × 1.07 µm, 3.36 × 0.92 µm, 3.09 × 0.87 µm, 3.28 × 0.93 µm, 3.19 × 0.70 µm, 3.41 × 0.86 µm
