03B987F9A407324441B4F828CB1BFB9D.taxon	etymology	Etymology: — Latin “ macrocarpus ” refers to the large basidioma. Diagnosis: — Characterized by large basidioma with a bright yellow-orange pileus, a well-developed, rugulose hymenophore, cream to pale yellowish stipe, noticeably thickened hyphal walls in the pileipellis, presence of clamp connections in all parts of the basidiomata, and distribution in tropical Asia. Holotype: — CHINA. Hainan Province: Changjiang County, Bawangling National Nature Reserve, elev. 650 m, 23 May 2019, N. K. Zeng 4050 (FHMU 3304). GenBank accession number: 28 S = MT 986061, ITS = MT 990453, TEF 1 = MT 990634. Description: — Pileus 10 – 16 cm diam, infundibuliform; margin slightly incurved, irregular, often wavy and lobed; surface dry, nearly glabrous, bright yellow-orange (2 A 7), darker brownish yellow (3 A 8) when old; context about 4 mm thick in the center of the pileus, white (1 B 1), unchanging in color when injured. Hymenophore composed of relatively well-developed, decurrent, branched to furcate gill folds, rugulose, becoming strongly intervenose with age, yellow-orange (2 A 7) to deep brownish yellow (3 A 7), unchanging in color when injured. Stipe 5.2 – 6.5 × 1.7 – 2.2 cm, central, subcylindric, solid; surface cream to pale yellowish (2 A 2 – 4); basal mycelium white (1 A 1). Taste and Odor not distinctive. Spore print not obtained. Basidiospores [340 / 17 / 5] 6.5 – 7.2 – 8 × 4 – 4.7 – 5 (– 5.5) μm, Q = (1.3 –) 1.4 – 1.75 (– 1.88), Qm = 1.54 ± 0.13, ellipsoid, smooth, thin to slightly thick-walled (up to 0.5 μm), hyaline in 5 % KOH, containing lipid droplets. Basidia 53 – 76.5 × 7.5 – 9 μm, narrowly clavate, slender, thin to slightly thick-walled (up to 0.5 μm), (4 –) 5 (– 6) - spored, colorless to hyaline in 5 % KOH; sterigmata 4 – 5 μm long. Subhymenium filamentose, composed of long, slender hyphae measuring 3 – 5 μm diam. Cystidia absent. Pileipellis a cutis 70 – 100 μm thick, composed of interwoven, filamentous hyphae, 4 – 9 μm diam, hyaline in 5 % KOH, slightly thick-walled (0.5 – 1 μm); terminal cells 53 – 112 × 5 – 9 μm, subcylindrical to subclavate with obtuse apex. Clamp connections present in all parts of basidiomata. Habitat: — Scattered to gregarious on the ground in a mixed forest of Pinus latteri Mason and Lithocarpus corneus (Lour.) Rehd. Known distribution: — Southern China (Hainan Province) and Laos. Additional specimens examined: — CHINA.
