MycoBank:—MB 824162
Diagnosis:—Differing from Craterellus odoratus in having a light yellow to greenish yellow pileus, white hymenophore, broader basidiospores and lack of aromatic odor.
Etymology:—The epithet luteus refers to the greenish yellow color of the pileus.
Holotype:— CHINA. Guangdong Province, Shaoguan City, Chebaling National Nature Reserve , at 114° 15′ 05′′ E, 24° 43′ 05′′ N, 28 July 2016, Xiangrong Zhong & Hao Huang ( GDGM 48105 About GDGM !) ( MG701171 for nrLSU and MG727896 for ITS). GoogleMaps
Description:— Basidiomata usually in caespitose clusters sized 9.2–9.8 × 7–11.4 cm, irregularly and often eccentrically tubiform, infundibuliform to broadly infundibuliform with age, arising from a stipe or pseudostipe. Pileus 3.1–5.6 cm in diam, inner or upper surface light yellow (2A4–5) to greenish yellow (1A6–8), subglabrous to minutely tomentose; pileal margin straight when very young, slightly curving outwards during early expansion, often wavy or lobed at maturity, sometimes splitting down to stipe with age. Hymenophore white (1A1), partially yellowish white (2A2), smooth to slightly folded. Context 0.8–2 mm thick, white or whitish to pale yellow, subcoriaceous. Stipe confluent with pileus, 3.2–4.5 cm high, 3–10 mm width, hollow, irregularly pitted, concolorous with hymenophore, usually somewhat curved and eccentric, without any obvious demarcation between pileus and stipe; stipe base covered with a small amount of white basal mycelium. Odor mild. Taste fruity.
Basidiospores [90/3/3] (8.5–)9–11(–12.5) × (5.7–)6–7.5(–7.8) μm, Q=1.3–1.75, ellipsoid to ovoid, smooth,
hyaline to yellowish in H 2 O and 5% KOH, inamyloid, with granular contents; wall 0.5 μm thick; hilar appendix 0.5 μm long. Basidia 51–71 × 6.7–9.7 μm, subcylindric to subclavate or cylindro-clavate, with irregular flexuous, hyaline to yellowish in H 2 O and 5% KOH, thick-walled, sterigmata 2–6, 4.3–6.9 μm long. Basidioles numerous, in clusters, cylindrical to subclavate, multiguttulate, intermixed with basidia, pale yellow in H 2 O and 5% KOH. Cystidia absent. Hymenium 55–75 μm thick. Tramal hyphae more or less interwoven, 5.5–7 μm wide, hyaline to faintly yellowish in H 2 O and 5% aqueous KOH. Pileipellis a trichoderm composed of cylindrical hyphae in 4.2–5.2 μm diam, which randomly extend from the inner surface. Clamp connections absent in all tissues.
Habit and habitat:—Caespitose, scattered or solitary on soil in broadleaved forests dominated by plants of Fagaceae and Theaceae . Under Castanopsis chinensis (Sprengel) Hance , Cyclobalanopsis glauca (Thunb.) Oerst. and Schima superba Gardner & Champ. trees, July–September.
