Description:—
Pileus
3.2–4 cm
diam., convex, umbilicate, light brown (7.5Y 7/2) in the center and slightly darker brown (5Y 7/2) towards the margin, becoming dark brown (5Y 7/2) when mature, pileus surface smooth, matt, with a shiny appearance, margin incurved, hygrophanous.
Lamellae
adnexed, creamy white (1.3BG5/0.6), pink (5YR7/4) at maturity, margin serrate and concolorous with faces, close, with 2–3 tiers lamellulae.
Stipe
centrally attached,
5–5.7 cm
length,
0.9–1.2 cm
diam., subclavate, solid, dry, fibrillose, creamy white (1.3BG 5/0.6), with a brown tinge in the lower portion, with a broad base.
Odor
aromatic resembling fruit.
Taste
not recorded.
Spore print
not taken.
Basidiospores
(9.9–) 10.1–13.1 (–13.9) × (7.1–) 7.9–10.8 (–11.1) µm, (avl × avw = 11.7 × 9.2 µm,) Q = 1–1.7, Qav = 1.3, subisodiametrical, with 4–7 angles, hyaline, thick-walled.
Basidia
33.5–57.4 × 11.5–17.4 µm, clavate to broadly clavate, hyaline, thin-walled, 2–4-spored.
Cheilocystidia
21.6–29 × 8–9.9 µm, narrowly clavate to narrowly utriform, hyaline, thin-walled.
Pileipellis
a cutis composed of septate, branched, thick-walled hyphae, 3.9–14.2 µm diam., hyaline to light brown in 5 % KOH.
Stipitipellis
a cutis composed of thin-walled hyphae, septate, branched, hyaline, 4.2–16.7 µm diam., Caulocystidia present throughout the stipe, clavate to cylindro-clavate, l×w= 106.1–133 × 20.4–27.1 µm, thick-walled, hyaline.
Clamp connections
abundant in all tissues.
