草菇(Volvariella volvacea)的有性过程以同宗结合为主。即可以不经过两株不同单孢子形成的初生菌丝配命,就可以形成能结菇的次生菌丝。草菇菌丝体不论其环境条件适宜与否,当生长到一定时期,总要形成厚垣孢子(Chlamydospore)。草菇的厚垣孢子呈圆形,直径40-60微米,红褐色至棕褐色。它的萌发温度略高于孢子,约39-41℃。萌发时先伸出一芽管;有的厚垣孢子萌发后膨大产生新的厚垣孢子,似芽殖分裂;有的则直接形成新的次生菌丝体。试验证明,草菇在营养基质十分贫瘠或在营养丰富的条件下,都能产生厚垣孢子。普遍认为,厚垣孢子的形成是草菇的遗传生理特性,而不是由于不良环境引起的。这一点与过去的说法不同。草菇的初生菌丝与次生
The sexual process of Volvariella volvacea is dominated by the same clan. That is, it is possible to form secondary mycelium that can bear mushrooms without the need of newborn mycelium formed by two different single spores. Mushroom mycelium regardless of their environmental conditions suitable or not, when grown to a certain period, always to form Chlamydospore (Chlamydospore). Mochizuki spore round, 40-60 microns in diameter, reddish brown to tan. Its germination temperature is slightly higher than spores, about 39-41 ℃. When germinating a bud tube; some chlamydospores germination after the enlargement of a new chlamydospore sprouting, bud bud like division; while others directly form a new secondary mycelium. Test proved that straw mushroom nutrition matrix is very poor or in nutrient-rich conditions, can produce chlamydospores. It is generally believed that the formation of chlamydospores is the genetic physiological characteristics of straw mushroom, not due to adverse environmental causes. This is different from the past. Fresh mushroom mycelium and secondary
