03DC27236B2ACB51FF00FB5C0CDADC58.taxon	etymology	Etymology: — The specific epithet refers to its ampullar conidia. Type: — CHINA, Sichuan Province, Yancheng city (27 ° 39 ′ 31 ″ N, 101 ° 14 ′ 16 ″ E), from a fruiting body of Boletus sp. 8 August 2018; Fu Rong & Liu Xing-Zhong (HMAS 291301, holotype), ex - type living culture CGMCC 3.20157. Fungicolous, growing on a fruiting body of Boletaceae sp. Asexual morph: Hyphomycetous. Mycelium forming a loosely attached layer on the fruiting body of the host (FIGURE 2 a). On PDA medium, colony forming a thick mat, white at the beginning, then becoming yellow (FIGURE 2 b, c). Mycelium superficial, copious, developing as floccose masses of septate, branched, warted and hyaline hyphae bearing robust conidiophores with white spore masses (FIGURE 2 b). Conidiophores hyaline, erect, flexuous, branched, septate, warted. With two types of conidiogenous cells phialidic and aleuriogenic (FIGURE 2 d – f, i). Type A: Phialides in 2 – 3 verticels, hyaline, warted, 16 – 40 × 4 – 5.5 μm (x ̅ = 25 × 5 μm, n = 30), attenuating to 1.5 – 3.0 μm at their apices (FIGURE 2 d, g, h). Phialoconidia acrogenous, hyaline, ampulliform, aseptate, 12 – 18 × 5.5 – 7.5 μm (x ̅ = 14.5 × 6.5 μm, n = 50) (FIGURE 2 k – m). Type B: Aleuriogenic discrete, on short side branches, hyaline, warted (FIGURE 2 e, f, i). Aleurioconidia hyaline at the beginning, becoming golden yellow when mature, subglobose to globose, thick - walled, aseptate, with angular tubercles on surface, 20 – 27 × 19 – 26 μm (x ̅ = 23 × 22.5 μm, n = 50) (FIGURE 2 e, f, i, j). Tubercles, cylindrical, 1 – 1.5 μm, often with apical depression, densely arranged (FIGURE 2 j). Sexual morph: Undetermined. Other material examined: — CHINA, Sichuan Province, Yancheng city (27 ° 39 ′ 31 ″ N, 101 ° 14 ′ 38 ″ E), from a fruiting body of Boletales sp. 8 Aug 2018; Fu Rong (YY 28 - 1), living culture CGMCC 3.20158. Notes: — The new species has grown on fruiting bodies of Boletaceae sp. containing only the asexual state. Among the known Boleticolous species of Hypomyces, H. ampullaris is morphologically similar to Sepedonium ampullosporum Damon in forming candelabrum like conidiophores and producing ampulliform conidia. But S. ampullosporum differs in having longer phialides (30 – 80 × 3.5 μm) and larger ampulloconidia (14 – 20 × 6 – 8 μm), and pigment discoloration of medium (Damon 1952, Sahr et al. 1999, TABLE 2).	en	Gu, Xin, Fu, Rong, Wang, Rui, Sun, Jing-Zu (2021): Two new Hypomyces associated with boletoid fungi in China.

03DC27236B24CB52FF00FB320F67DAF5.taxon	etymology	Etymology: — The specific epithet refers to the type locality of the fungus. Type: — CHINA, Sichuan Province, Yancheng city (27 ° 39 ′ 37 ″ N, 101 ° 14 ′ 11 ″ E), from a fruiting body of Boletus sp. 8 August 2018; Fu Rong & Liu Xing-Zhong (HMAS 291302, holotype), ex - type living culture CGMCC 3.20159. Fungicolous, growing on a fruiting body of Boletaceae sp. Asexual morph: Hyphomycetous. Mycelium forms a loosely attached layer on the fruiting body of the host (FIGURE 3 a). On PDA medium, colony tomentose to pubescent, white at the beginning, then becoming yellow (FIGURE 3 b, c). Mycelium superficial, developing as floccose masses of septate, branched, smooth and hyaline hyphae bearing robust conidiophores with golden yellow spore masses (FIGURE 3 b). Conidiophores hyaline, erect, flexuous, septate, smooth. With two types of conidiogenous cells phialidic and aleuriogenic (FIGURE 3 d – i). Type A: Phialides in 2 – 3 verticels, or solitary, 65 – 180 × 2 – 3 μm (= 115 × 2.5 μm, n = 30), attenuating to 1.0 – 2.0 μm at their apices (FIGURE 3 d – f j). Phialoconidia acrogenous, hyaline, thin - walled, ellipsoid to clavate, aseptate, 11.5 – 18 × 3 – 6 μm (= 14.5 × 5 μm, n = 50) (FIGURE 3 l). Type B: Aleuriogenic discrete, on short or long side branches (FIGURE 3 d, h, i). Aleurioconidia hyaline at the beginning, becoming golden yellow when mature, subglobose to globose, thick - walled, aseptate, with angular tubercles on surface, 8.5 – 15.5 × 8 – 15 μm (12.5 × 12 μm, n = 50) (FIGURE 3 h, i, k). Tubercles densely, cylindrical, 1 – 2 μm, often with apical depression (FIGURE 3 k). Sexual morph: Undetermined. Other material examined: — CHINA, Sichuan Province, Yancheng city (27 ° 39 ′ 36 ″ N, 101 ° 14 ′ 40 ″ E), from a fruiting body of Boletales sp. 8 Aug 2018; Fu Rong (YY 30 - 1), living culture CGMCC 3.20160. Notes: — The new species grows on fruiting bodies of Boletaceae sp. containing only the asexual state. Among the known Boleticolous species of Hypomyces, H. sichuanensis is morphologically similar to H. chrysospermus Tul. & C. Tul., H. microspermus Rogerson & Samuels, and Sepedonium laevigatum Sahr et Ammer in forming poorly developed verticills conidiophores and the shape and size of aleurioconidia (Rogerson & Samuels 1989). Compared with H. chrysospermus, H. microspermus, and S. laevigatum, aleuriospores and phialoconidia of H. sichuanensis averaged somewhat smaller than those of H. chrysospermus (14 – 21 μm for aleuriospores, and 5 – 27 × 3 – 11 μm for phialoconidia) and S. laevigatum (14 – 19 μm for Aleuriospores, and 8 – 24 × 3.5 – 9.5 μm for phialoconidia) but larger than that of H. microspermus (9 – 15 μm for Aleuriospores, and 6.4 – 11.7 × 4 – 6.5 μm for phialoconidia) (Sahr et al. 1999, TABLE 2). Additionally, H. sichuanensis also differs from S. laevigatum by no yellow discoloration of medium (Sahr et al. 1999).	en	Gu, Xin, Fu, Rong, Wang, Rui, Sun, Jing-Zu (2021): Two new Hypomyces associated with boletoid fungi in China.
