771E87A3FFB3FFB81D9F06BD71E0FB16.taxon	diagnosis	Diagnosis: — Differs from Phaeoclavulina cinnamomea by having orange with pale red tinge basidiomata, shorter basidiospores, and basidia. Holotype: — CHINA, Hunan Province, Chenzhou County, 25 ° 97 ′ 84 ″ N, 113 ° 71 ′ 78 ″ E, elev. 1115 m, 16 June 2024, P. Zhang (MHHNU 11750, GenBank Accession number of ITS: PQ 589930, GenBank Accession number of LSU: PQ 579885). Etymology: — aurantilatea, from the Latin aurantiacus and laetus, refers to the orange with a pale red tinge in the holotype. Description: — Ramaroid, 40 – 65 mm tall, 35 – 55 mm broad, orange [5 A 7 – 8, zinc orange], pale red [6 A 7] with age. Stipe single or falsely fasciculate, 10 – 15 mm long, concolorous with branches, smooth, white mycelium at the base, not changing color on bruising. Branches dichotomous to polychotomous, divided two to four times, primary branches thick and in cross-section rounded; the diameter of terminal branches becoming short, dark reddish brown with age, bifurcation narrowly U-shaped. Apices acute, relatively short, dichotomous, concolorous with branches. Context whitish. Taste not recorded; odor not distinctive. Macro-chemical reactions: 10 % FeCl 3: greenish; Melzer's reagent: negative; 10 % KOH: leaches dull orange and pale red. Basidiospores [60 / 3 / 2] (9.5 –) 10.0 – 11.5 (12.0) × (4.8 –) 5.0 – 6.5 (– 6.8) μm [Q = 1.61 – 2.07 (– 2.16), Qm = 1.83 ± 0.13], elongate and sub-cylindrical, bend slightly at the end, thick-walled, pale yellow in 5 % KOH, cyanophilic, with a distinct apiculus, surface coarse, echinulate, truncate (volcanic) spines 0.8 – 1.5 μm long, acute. Basidia 35 – 50 × 10 – 12 µm with four sterigmata 5 – 8 µm long, hyaline, clavate, clamp connections at base. Cystidia absent. Context hyphae in parallel arrangement, with clamp connections but not at every septum, thin-walled, tramal hyphae of branches 3.0 – 5.0 μm wide, sometimes flat to 7.0 μm wide. Habit and distribution: — Solitary, growing on the soil in the mixed forest, basidiomata generally occur in early summer. Known only from the type region, Hunan Province, China.
