ABSTRACT
Features fundamental to the identi–cation of Chaetomium species include the presence of hairs or setae covering the ascomata, the size and shape of ascospores, and the presence and position of germ pores. Among the similar Chaetomium species (i.e., C. gangligerum, C. raii, C. jodhpurense, and C. fusisporum), C. gangligerum produces broader ascospores (12-15 μm × 7.5-9.5 μm) and usually forms chlamydospores; C. raii has smaller ascospores (10-13 μm × 5.5-7.5 μm), and C. jodhpurense and C. fusisporum have larger ascospores (14-19 μm × 6-8 μm and 14-17 × 7-8 μm, respectively).
