description
Description. Pileus 6 - 26 mm diam, subhemispheric in young, becoming convex to plane convex and centrally depressed, some finally irregularly infundibuliform; margin incurved when young, becoming inflexed to somewhat straight, undulate or irregular or more or less crenate, not or obscurely translucid striate; surface dry, with appressed fibrils at center when young, glabrous at remaining areas, with waxy appearance, bright yellow-orange (5 A 5 - A 8) with tiny white to light yellow scales in the center when young, paler at edge when young. Hymenophore decurrent or shortly decurrent, with gill-like folds up to 2 mm deep, subdistant to more frequently distant, at times forked, moderately thick with margin entire or often irregular or eroded, frequently intervenose, some specimens (especially towards the stipe) with irregular low and sinuous veins, often with lower irregular anastomosis among the folds, in some specimens the anastomosis occur practically in the whole hymenophore, while in others only at some areas, especially at pileus margin, with some short lamellulae-like folds, concolorous with the pileus. Stipe (10 -) 15 - 42 x 2 - 6 mm, broadened towards the apex, somewhat fused, compressed at times or furrowed, solid but soon fistulous to hollow, glabrous, concolorous with pileus. Context fleshy, concolorous with pileus or somewhat paler, with waxy appearance, odor mild, agreeable; taste mild, agreeable. Basidiospores 6 - 9 (- 9.5) x 4.5 - 5 µm [X - = 7.6 - 7.8 x 4.9 - 5 µm, Q - = 1.52 - 1.57 (n = 3)], broadly ellipsoid, smooth, thin-walled, hyaline, inamyloid, with granular contents or refractive droplets. Basidia 50 - 83 (- 89) x (6 -) 7 - 10 µm, narrowly clavate to subcylindrical, with 2 - 5 sterigmata, thin-walled, hyaline; subhymenium composed of cylindrical hyphae 4 - 6 µm diam. Cystidia absent. Pileipellis composed of intermingled hyphae of 4 - 7 µm diam, cylindrical, hyaline, yellowish in group, terminal hyphae (23 -) 25 - 75 (- 80) x (3.5 -) 4 - 8 µm, mostly cylindrical, often subclaviform, subventricose or somewhat narrowly utriform, moderately straight to flexuous, inamyloid, thick-walled (<1 µm thick), smooth, hyaline. Pileus trama composed of cylindrical to inflated hyphae, 4 - 7 µm diam, slightly thick-walled (<1 µm thick), hyaline, some with weakly refringent contents. Hymenophoral trama composed of hyphae 4 - 5 µm diam, thin-walled, some with weakly refringent contents. Clamp connections present in all tissues.
diagnosis
Diagnosis. Differing from other related Cantharellus species (subgenus Parvocantharellus) by the pileus surface with appressed fibrils at center, broadly ellipsoid basidiospores 6 - 9 (- 9.5) x 4.5 - 5 µm [Q - = 1.52 - 1.57 (n = 3)], pileipellis terminal hyphae (23 -) 25 - 75 (- 80) µm x (3.5 -) 4 - 8 µm, mostly cylindrical, often subclaviform, subventricose or somewhat narrowly utriform.
etymology
Etymology. Referring to a small, yellow chanterelle; from parvus (Lat.): small and Cantharellus flavus (Lat.): yellow
