The first human phaeohyphomycotic infection caused by Xylohypha emmonsii is described. The patient, an 83-year-old woman, developed a purpuric lesion on her left arm. The pale brown fungal elements observed in biopsy tissue consisted of thin- to thick-walled, oval to spherical, yeastlike cells with single and, occasionally, multiple buds; chains of budding cells; cells with internal septations in one and, rarely, two planes; and septate hyphae. In culture, X. emmonsii grew moderately fast at 25 degrees C, showed minimal growth at 37 degrees C, and failed to grow at 40 degrees C. It produced acropetal chains of one-celled (rarely two-celled) conidia laterally and terminally directly from vegetative hyphal cells.
首例由埃蒙斯木丝霉引起的人类暗色丝孢霉病感染病例被报道。患者为一名83岁女性，其左臂出现紫癜性损害。活检组织中观察到的淡褐色真菌成分包括薄壁至厚壁、椭圆形至球形的酵母样细胞，有单个且偶尔有多个芽；芽生细胞链；在一个平面（很少在两个平面）有内部隔膜的细胞；以及有隔膜的菌丝。在培养条件下，埃蒙斯木丝霉在25℃生长适中，在37℃生长微弱，在40℃不生长。它从营养菌丝细胞侧面和末端直接产生单细胞（很少为双细胞）分生孢子的向顶链。
