This study is an investigation of the Mucorales in the acidic humus of Yang-ming-shan. The 34 samples were collected from eight different areas on Yang-ming-shan. By repeated cultivation and observation, 19 species were identified. They belong to seven different genera: 11 species of Mucor, 2 species of Rhizopus, 2 species of Cunninghamella, 1 species of Coemansia, 1 species of Syncephalastrum, 1 species of Mortierella (2 varieties), and 1 species of Zygorhynchus. Among those collected, Mucor, Cunninghamella and Rhizopus were the genera most frequently encountered. Newly reported species of Mucorales to Taiwan are: Mucor luteus, M. varians, M. heterosporus, M. genevensis, Rhizopus arrhizus, Zygorhynchus moelleri, Mortierella ramanniana var. ramanniana, Mortierella ramanniana var. and an unidentified species of Coemansia.
