摘　　要：从山西省祁县一麻雀窝中的羽毛上分离到一嗜角蛋白的金孢属新种——山西金孢。采用分子系统学结合经典形态学对其进行了描述和鉴定,其主要鉴别特征是:具球拍状菌丝,10.8–16.2×5.4–6.5μm;顶侧生分生孢子着生于菌丝上或短的突起或短柄上,单生或2–3个串生,多数长倒卵形,6.5–11.9×3.2–6.5μm,少数棒状至柱状,8.6–17.3×2.2–4.3μm;基痕较宽1.9–4.3μm,大多数产孢细胞与分生孢子连接处具有膨大的"领状"结构;间生孢子不规则桶状至肾形,8.6–13×3.2–6.5μm。A new keratinophilic fungal species, Chrysosporium shanxiense, was isolated from a feather in a sparrow＇s nest in Qixian County, Shanxi Province, China. Its main diagnostic characteristics were as follows： racquet hyphae present, 10.8-16.2×5.4-6.5μm; terminal and lateral conidia mostly sessile or on short protrusions, sometimes on side branches, mostly solitary or on short chains, mostly oblong-obovate, 6.5-11.9×3.2-6.5μm, sometimes clavate to cylindrical, 8.6-17.3×2.2-4.3μm, with broad basal scars （1.9-4.3μm） and inflated collar-shaped structures between conidiogenous cells and conidia, intercalary conidia irregularly tubby to reniform, 8.6-13×3.2-6.5μm
