CB388781FF8BFFFCD3D8FA6EFE8A0303.taxon	materials_examined	Holotype: GMB 1061 Basidiomata annually, gregarious, gelatinous. Pileus 3.5 – 11 × 2.5 – 7 mm, glabrous, flabelliform, reniform, semicircular to subcircular, sometimes circular; surface snow white (1 A 1) to greyish white (1 B 1) or pale yellow (4 A 4) when fresh, dark grey or brownish grey (6 E 2) upon drying, convex, reticulate pattern, pruinose in young, becomes glabrous in age; margin straight or incurved, crenulate; context thick. Hymenophore consisting of up to 120 pores per basidiomata; pore edges pale white (fresh and dry), 10 µm wide, thin, glabrous; Pores 0.1 – 0.5 mm in diam., irregular or radially elongated, polygonal, increase in size near the base and become smaller toward the edge. Stipe mostly present, 1.5 – 3 × 0.5 – 1 mm when young, sometimes 9 × 3 mm in age, concolourous with pileus surface, slightly pulverulent, laterally attached to the pileus, subcylindrical with a slightly swollen base. Basidiospores (3.7 –) 5.0 – 8.7 (– 9.3) × (2.8 –) 3.5 – 6.5 (– 7.2) µm, L = 6.68 μm, W = 4.69 μm, Q = 1.3 – 1.6, Qm = 1.43, subglobose to broadly ellipsoid, hyaline, thin-walled, smooth, guttules, amyloid. Basidia 21 – 29 × 7 – 9.5 μm, clavate to cylindrical, 2 - spored, sterigmata up to 5 μm long, apex broadly rounded; basidioles 17 – 31 × 6 – 9 µm, similar in shape to the basidia. Cheilocystidia 19 – 36 × 4.7 – 8.7 μm, cylindrical or clavate, obtuse, thin-walled. Gloeocystidia 17 – 68 × 14 – 31.8 μm, cylindrical, ellipsoid to subglobose with dense brown or dark brown contents. Acanthocystidia absent. Pileipellis hyphae subparallel, smooth to diverticulate, thin-walled, 2 – 5 μm in diam. Tramal hyphae subparallel with dense contents and some collapsed, thin-walled, 2 – 4 μm in diam. Hyphae in stripe cytoplasmic content, interwoven, branching, 2 – 3 μm broad. Clamp connections present in all tissue types. Bioluminescence absent.

CB388781FF8BFFFCD3D8FA6EFE8A0303.taxon	distribution	Distribution and ecology: Favolaschia variistipitata grows on dead bamboo and is distributed in subtropical areas of Yunnan Province, China. Notes: Favolaschia variistipitata within the Favolaschia sect. Anechinus was collceted from subtropical area of Yunnan Province, China. Phylogenetically, two samples of F. variistipitata (GMB 1061 and GMB 1062) formed a distinct linage with high support (99 % BS / 1 PP, Figure 1) that is sister to F. tonkinensis and closely related to F. tenuissima Q. Y. Zhang & Y. C. Dai (797: 2023). However, F. tonkinensis can be easily distinguished from F. variistipitata by its bigger basidiomata (6 – 24 mm vs. 3 – 11 mm), and bigger basidiospores (8 – 12.5 × 7 – 10.5 µm vs. 5.0 – 8.7 × 3.5 – 6.5 µm, Singer 1974), shorter stipe (1 – 3 × 0.5 – 1 mm vs. 9 × 3 mm), and the former has the bioluminescence characteristics. While F. tenuissima differs from F. variistipitata in having smaller basidiomata (3 – 5 × 1 – 3 mm vs. 3.5 – 11 × 2.5 – 7 mm), few pores (10 – 20 vs. 120), smaller cheilocystidia (15 – 23 µm × 3 – 6 µm vs. 19 – 36 × 4.7 – 8.7 μm), and the absence of gloeocystidia.	en	Lu, Wenhua, Chen, Xuemei, Kumla, Jaturong, Suwannarach, Nakarin, Elgorban, Abdallah M., Dai, Dong-Qin, Tibpromma, Saowaluck, Karunarathna, Samantha C.
