Abundant rhizomorphic mycelium connecting hardwood stick. Larger patches between rhizomorphs covered with spines. Locally abundant. All structures inamyloid. Seemingly monomitic. At least some generative hyphae clamped. Subicular hyphae encrusted, clamped and with rounded crystals adhering to them. Cystidia absent but basidioles abundant. Basidia 2 to 4 sterigmate with at least some sterigmata up to 4.2 µm long. Most basidia with yellow refractive contents in Melzer's reagent. Contents also visible in water but not yellow. Basidia measured: 28.1 µm, 40.3 µm, 42.1 µm. Spores smooth.
