Growing on hardwood twigs and leaf litter on the bank of a road near Rhododendron sp., Quercus spp., Betula sp., Liriodendron tulipifera, Acer sp. and likely other hardwoods. Cap dry and smooth; finely translucent-striate at margin; 1.9 to 4.1 mm wide and 1.3 to 2.3 mm tall. Gills very finely adnexed – almost free; with 1 tier of lamellulae. Stems smooth except for very finely pruinose at the apex; dry; 11.5 to 18.8 mm long and 0.3 to 0.4 mm wide. Basal mycelium white and sparse. Odor not distinctive. All lamellar and pileipellis structures inamyloid. Pileipellis a hymeniderm. Yellowish resinous substance present on gill margins in Melzer’s reagent. Pleurocystidia absent or scarce. Hyaline cheilocystidia smooth and thin-walled, mostly covered in the the resinous substance. Basidia 4-sterigmate. Spores hyaline, smooth and thin-walled. Spore measurements: (7.3) 8 – 10 (11.6) × (3.1) 3.3 – 4.3 (4.4) µm; Q = (1.9) 2.1 – 2.8 (3); N = 25; Me = 9.1 × 3.7 µm; Qe = 2.5.
