Distinguishing microscopic characteristics of the mushroom include the relatively large, distinctly amyloid spores (turning blue to black when stained with Melzer's reagent), the smooth, spindle-shaped cheilocystidia (cystidia on the gill edge), the absence of pleurocystidia (cystidia on the gill face), the diverticulate hyphae of the cap cuticle, and the absence of clamp connections.

The stem is long and slender compared to the size of the cap, typically 7 to 10 cm (2.8 to 3.9 in) tall by 1 to 2.5 mm (0.04 to 0.10 in) thick, cylindrical, slightly enlarged at the base, and hollow.

[2] The spores are ellipsoid, smooth, colorless, distinctly amyloid (absorbing iodine stain from Melzer's reagent), thin-walled, and measure 11.5–14 by 6–8 μm.

The cheilocystidia (cystidia found on the gills edges) are 32–39 by 5–12 μm, abundant, spindle-shaped to roughly club-shaped, often apically broadly rounded, smooth, colorless, and thin-walled.

The cap cuticle is made of parallel, bent-over hyphae that are 2–5 μm wide, cylindrical, and densely covered with warty or finger-like thin-walled diverticulae that are colorless or contain cytoplasmic brownish pigment.

The layer of hyphae underlying the cap cuticle are parallel, colorless or with cytoplasmic brownish pigment, dextrinoid, and have short and inflated cells measuring up to 30 μm wide.

Fruit bodies are found solitary or scattered, on dead leaves and twigs in low-elevation forests dominated by the oak species Quercus myrsinaefolia and Q. serrata.
