Holotype:
THAILAND, Chiang Mai Province, Kanlayaniwattana district, Huai Ban Rang Fish Sanctuary, 7 Nov. 2019, S. Sommai, P. Khamsuntorn, holotype BBH 49226.
Habitat:
On soil under Pinus merkusii trees (Pinaceae)
Description:
Pileus medium to large-sized, 1.8-7.0 cm diam, convex, expanding to applanate when mature, centre infundibuliform with age; margin even, arched when old, sometime cracking, surface smooth, viscid when moist, greyish purple when young, purplish green when mature, unchanging when bruised. Lamellae decurrent, narrow, crowded, equal, average, white, unchanging when bruised. Stipe 1.0-1.8 × 2.0-5.5 cm, central, tapering, longitudinally, smooth, dry, striate, firm, solid, white, unchanging when bruised. Context 1.0-3.0 mm thick, white, without colour changing when bruised. Odour indistinct. Taste unrecorded. Spore print not obtained. Basidiospores 6.1-9.3 × 6-8 μm, Q = 0.89-1.59, globose to subglobose or broadly ellipsoid, ornamentation amyloid, minute warts to bluntly conical to subcylindrical, not exceeding 1.0-2.0 μm in height; suprahilar plage indistinct, hilar appendix distinct, 1.0-1.5 μm in height, not amyloid; hyaline in 10% KOH. Basidia 30.9-43.8 × 5.0-9.0 μm, 4-spored with some 2-spored basidia present, narrowly clavate to clavate, sterigmata 3.0-6.0 μm in length. Lamellar trama mainly composed of nested sphaerocysts, 15.0-25.0 μm diam, and filamentous hyphae 3.0-6.5 μm thick, hyaline. Hymenial cystidia dispersed to moderately numerous, ca 800/mm², 36.3-49.7 × 4.3-7.0 μm abundant, clavate to subfusiform, with oilcontent, thin-walled, round or mucronate apex, non-reaction in sulfovanillin; abundant near the lamellae edges, 45.0-77.5 × 7.5-10.0 μm, similar to those on the sides. Lamellae edges fertile, marginal cells 10.0-32.5 × 7.5-12.5 μm, mainly clavate and shorter than basidia. Pileipellis metachromatic in Cresyl Blue, not sharply delimited from underlying context, 25.0-62.5 μm, deep, not gelatinised, a trichodermium, composed of hyphae 2.0-5.0 μm wide, thin-walled, septate. Acid-resistant incrustations absent. Hyphal terminations near the pileus margin scarcely branched, occasionally flexuous, thin-walled, septate, terminal cells 12.5-20.0 × 3.8-5.0 μm, occasionally cylindrical, rarely clavate, fusiform, some irregularly inflated near the base. Terminal cells of hyphae near the pileus centre, often clavate and longer 22.5-32.5 × 3.8-7.0 μm. Pileus trama interwoven with sphaerocysts. Pileocystidia near the pileus margin mainly 1-celled, clavate-pedicelate, often with strongly constricted and attenuated basal part, thin-walled, 52.5-87.5 × 5.0-8.3 μm, non-reaction in sulfovanillin. Pileocystidia near the pileus centre similar. Stipitipellis a cutis, composed of hyphae 2-4.5 μm in width, thin-walled, septate. Caulocystidia 38.5-42.5 × 5-6.5 μm, cylindrical, not abundant. Clamp connections absent.
