Zhao, J.J. Hu, B. Zhang & Y. Li sp. nov. Figs 4 , 5 Holotype. China. Jilin Province, Baishan City, Fusong County, Quanyang Town, alt. 780.4 m, 42.23°N , 121.30°E , 22 August 2021, G. P. Zhao, J. J. Hu, and Bo Zhang (HMJAU 61463, GenBank Acc. nos.: nr LSU = OM509446, OM509447, tef -1α = ON125913, ON125914). Etymology. Striatus : referring to the fringe of pileus. Diagnosis. Differs from other Craterellus species by the fibrillose, greyish-brown to yellowish-brown, fully perforated pileus with a brown fringe, the hymenophore with a forking vein, not anastomosing and non-discolouring upon drying. Figure 4. Craterellus striatus (HMJAU 60412, holotype) A Fresh basidiocarps B Stipe C Pileus D Hymenophore. Scale bars: 1 cm ( A, B ) Description. Fruiting body 12-45 mm high. Pileus 3-21 mm in diam., 1-10 mm tall, plane-convex firstly, soon infundibuliform and usually perforated continuous to the base of the stipe; margin inrolled when young, then expanding outwards, old becoming incurved, broadly wavy; surface blackish-brown, cream near the margin at first, gradually lighter to the centre with age, yellowish-brown finally, turning pale greyish-brown when drying, covered with brown fringe and fibrillose scales. Hymenophore decurrent, consisting of longitudinal ridges (<1 mm) with prominent forking, cross vein and off-white. Stipe 11-35 x 1-6 mm, cylindrical, inflated at the base, up to 10 mm in diam., hollow, central, smooth, blackish-brown. Text leathery, dirty white. Odour light. Taste unknown. Spore print not obtained. Figure 5. Microscopic characteristics of Craterellus striatus (HMJAU 60412) A spores B basidiobasidia C pileipellis. Scale bars: 10 μm ( A ); 20 μm ( B ); 40 μm ( C ). Basidiospores (6.5)6.8-7.4-8.0(8.8) x (5.0)5.1-5.5-6.0 μm , Q = (1.18)1.22-1.36-1.53(1.73), Qm = 1.36 +/- 0.12, broad ellipsoid to ellipsoid, smooth, thin-walled, hyaline to pale yellow in 5% aqueous KOH, inamyloid. Basidia (34)40-67(68) x 6-9 μm , slender, sterigmata 2-6. Cystidia absent. Hymenium in transverse section 45 μm thick, yellowish-brown in 5% aqueous KOH. Pileipellis scarcely differentiated from trama, a cutis of largely cylindrical hyphae, yellowish-brown in 5% aqueous KOH; individual hyphae (30)40-70(73) x (4)5-14(15) μm , thin-walled, encrusted, branched frequently, secondary septation absent, hyaline in 5% aqueous KOH. Pileus trama up to 500 μm thick, subparallel, yellowish-brown in 5% aqueous KOH; individual hyphae (29)33-60(125) x (4)5-12(13) μm , cylindrical, thin-walled, encrusted, branching frequently, secondary septation absent. Subhymenium up to 10 μm thick. Stipitipellis composed of a tightly-packed mass of subparallel, narrow, cylindrical hyphae, yellowish-brown in 5% aqueous KOH; individual hyphae (33)37-79(102) x 4-13(16) μm , thin-walled, hyaline to pale yellow in 5% aqueous KOH, branched frequently, secondary septation absent. Clamp connections absent. Habitat. Scattered to gregarious on the ground in a coniferous and angiosperm mixed forest.
