Notes:
Collector(s): Alden C. Dirks
Collection_Number(s): ACD0242
Habitat: mixed deciduous forest
Substrate: fallen hardwood branch
Spore_Print: whitish/pale cream
Macroscopic_Features: Basidiomata beginning orbicular, becoming effused with a small, reflexed edge. Hymenium salmon-brown in color, cracking when dry.
Microscopic_Features: Basidiospores: ellipsoid in dimension, lacrymoid in shape; hyaline, inamyloid, uniseriate, without guttules; length (7.3) 7.8-9.2 (10.4) µm, x̄ = 8.5 µm; width (5.4) 5.8-6.9 (7.9) µm, x̄ = 6.4 µm; Q (1.2) 1.3-1.4 (1.6), x̄ = 1.3 (n = 30 spores measured in tap water).
Basidia: terminal, often arising from small, squiggly hyphae; one developing basidium (with immature sterigmata) measured as 51.8 × 7.3 µm.
Hyphal system: monomitic, clamp connections present at all septa; subicular hyphae width (3.6) 3.6-4.8 (5.4) µm (n = 10 measured in KOH + phloxine); oily inclusions common in subicular hyphae (reminiscent of Sistotrema).
