New wh ite Auricularia cornea Ehrenb ＂white wood ear＂is an excellent strain that is obtained by systematic breeding for heteromorphosis Auricularia cornea Ehrenb.. From vaccination to ear, it takes 45-55 days with ear or discoid colloi porocarps, and the edge is arc when the fruit is small, posterior border is like wave after maturity. Also, the fresh ear is milky white or pure white with smooth, shiny and lightly transparent surface, and the ear diameter is 2-12 cm with the thickness of 0.1-0.2 cm. The back of dry ear is light yellow with short white naps and there is almost no few folds, and the cladding is light yellow. The creamy white recover to white after rewatering. The regional trials： the average output was 86.9 kg per thousand bag（dry ears） in 2011-2012 years,and there was no significant difference in contrast to Auricularia cornea Ehrenb., then the average output was 91.2 kg per thousand bags（dry ears） in 2012-2013 years, of which there was still no significant difference in contrast to Auricularia cornea Ehrenb.. Production test： the average production yield was 91.0 kg per thousand bags（dry ears）in 2013-2014 years, then the average production yield was 91.1 kg per thousand bags（dry ears） in 2014-2015 years.The white wood ears had no significant difference with Auricularia cornea Ehrenb. in two years.
