03E0A133794C1547CB8F91FD922EF979.taxon	materials_examined	Type species: — Septocystis minor F. C. Huang Etymology: — “ Septocystis ” refers to the genus having the special cystidia with septa at tip. Description: — Basidiomata annual, resupinate, corky to hard leathery. Pore surface white to dark gray; pores circular, angular, irregular; most dissepiments thick, entire to lacerate. Hyphal system dimitic; generative hyphae bearing clamp connections, skeletal hyphae dominant, frequently branched, usually well differentiated from the main part in trama, IKI−, CB +, tissues darkening in KOH. Dendrohyphidia absent; hyphal pegs occasionally present in the hymenium; Crystals frequent or few among subhymenium and hymenium. Cystidia fusoid, long clavate to flask shaped, usually with 1 – 3 septa at tip, but some turn to be a thin membrane, some to be a short to long irregular linear object; cystidioles fusoid, long clavate to flask shape; basidia barrel-shaped to cylindrical, with four sterigmata and a basal clamp connection; basidiospores cylindrical, IKI−, CB +. Distribution: — Known from China.	en	Huang, Fu-Chang, Lin, Jian-Tian (2025): Septocystis (Polyporales, Basidiomycota), a new genus of Polyporaceae from Southern China.

Hyphal system dimitic; generative hyphae bearing clamp connection, skeletal hyphae from trama dominant, frequently branched, most skeletal hyphae with a well differentiated basal stalk. Cystidia fusoid, long clavate and flask shaped, usually with 1 – 3 septa at tip, and some turn to be a thin membrane, some short or long irregular linear object.

Holotype: — China, Guangxi Autonomous Region, Chongzuo, Longzhou County, Nonggang Nature Reserve (106 ° 42 ′ 28 ″ – 107 ° 04 ′ 54 ″ E, 22 ° 13 ′ 56 ″ – 22 ° 39 ′ 09 ″ N), on rotten angiosperm wood, July 26, 2022, Fu-Chang Huang, GXU 12865 (Holotype), GenBank accession numbers OR 634847 (ITS), OR 634848 (nLSU), PQ 304574 (RPB 2). Etymology: — “ minor ” refers to the small pores. Description: — Basidiomata annual, resupinate, cork to hard leathery, up to 26.7 cm long, 5.5 cm wide and 3 mm thick at center. Sterile margin absent, or up to 1.5 mm wide with finely velutinous, white (N, 9.5 /) when fresh, become brown (7.5 YR, 5 / 4) when bruised, pale yellow (2.5 Y, 8 / 4) to olive brown (2.5 Y, 4 / 3) when dry. Pore surface white (2.5 Y, 8 / 1), gray (2.5 Y, 5 / 1) to dark gray (2.5 Y, 4 / 1) when fresh, gray (2.5 Y, 6 / 1) to dark grayish brown (2.5 Y, 4 / 2) when dry, pores angular, circular, irregular, 6 – 7 pores per mm, dissepiments thin to thick, entire to lacerate; tubes concolorous with pore surface, cork to hard leathery, up to 2.5 mm long; context corky, yellow (2.5 Y, 8 / 6) to olive brown (2.5 Y, 4 / 3). Hyphal system dimitic. Tissues negative reaction in Melzer reagent, becoming brown in 5 % KOH, and positive reaction in Cotton Blue. Generative hyphae bearing clamp connections. Generative hyphae from context hyaline, thin-walled, moderately branched, 1.9 – 5.9 µm diam; skeletal hyphae dominant, thick-walled, broad to narrow lumen, even subsolid, frequently branched, 1.3 – 4 µm diam. Generative hyphae from trama hyaline, thin-walled, usually branched, 1.3 – 4.6 µm diam. Skeletal hyphae from trama dominant, thick-walled with broad to narrow lumen, even subsolid, frequently branched, most skeletal hyphae with a well differentiated basal stalk, 3.9 – 8.1 µm wide, the branches 1.2 – 4 µm wide. Cystidia fusoid, long clavate or flask shaped, usually with 1 – 3 septa at tip, and some turn to be a thin membrane, some a short or long irregular linear object, hyaline, thin-walled, 11.5 – 59.4 × 3.1 – 7.2 µm, L = 23.36 µm, W = 5.21 µm.
