摘　　要：为准确鉴定和了解木耳属野生菌株Aa-019的菌丝生长特点,通过形态鉴定法、ITS分析法并开展菌丝生长所需碳源、氮源、最适温度以及适宜pH等筛选试验。结果表明,菌株Aa-019为尚未报道的毛木耳菌株,菌丝的最适生长温度为20℃,在含有甘露醇20.0 g·L^(-1)和酵母粉6.0 g·L^(-1)且pH为6.7的培养基上生长最快。In order to accurately identify the wild strain Aa-019 and understand its mycelial growth characteristics,using morphological identification,ITS sequences analysis and carrying out optimization experiments of carbon source,nitrogen source,growth temperature and suitable pH for its mycelia grow.The results showed that mycelia of strain Aa-019 which was identified as no reported new strain Auricularia cornea,and grew fastest on the medium containing mannitol 20.0 g·L^(-1) and yeast powder 6.0 g·L^(-1),with the pH of 6.7,and the best fit temperature was 20℃.
