具有绿色子囊孢子的木霉属两个新种——波密木霉和绿领木霉

在广东和西藏进行子囊菌资源调查,发现木霉属具有绿色子囊孢子的两个新种,命名为波密木霉和绿领木霉。波密木霉的子座小型,橙褐色至黄绿色,垫状,分生孢子梗为trichoderma型。绿领木霉的子座微小,垫状至陀螺形,淡黄色至淡绿色,其孔口处明显色暗,皮层表面带绿色。基于RPB2和TEF1基因的系统发育分析表明,两个新种作为散在的末端分枝夹杂在具有绿色子囊孢子的已命名分支之间。

Trichoderma bomiense and T. viridicollare,two new species forming separate terminal lineages among the green-ascospored clades of the genus

Two green-ascospored new species, Trichoderma bomiense and T. viridicollare, are described and illustrated based on collections from Guangdong Province and Tibet Autonomous Region of China. Trichoderma bomiense collected at a high altitude has small brownish orange to greenish yellow or brown pulvinate stromata and trichoderma-like conidiophores. Trichoderma viridicollare is distinctive by its tiny pale yellow to pale green and pulvinate to turbinate stromata with very dark ostioles and greenish cortical tissues. Sequence analyses of the combined translation elongation factor 1-alpha and RNA polymerase II subunit B revealed that both fungi formed separate terminal lineages together with the clades of Trichoderma producing green ascospores.
