枝顶孢霉对毒光盖伞子实体形成的影响

Effects of Acremonium strictum on fruit-body formation of Psilocybe venenata

报道枝顶孢霉Acremonium strictum对毒光盖伞Psilocybe venenata子实体形成的影响。拮抗试验结果表明它们之间存在着较弱的干扰竞争作用;人工培养时,毒光盖伞混合菌株产生大型、小型和畸形3种类型的子实体,推测毒光盖伞畸形子实体的形成可能是枝顶孢霉寄生的结果,为毒光盖伞的人工栽培和进一步合理利用、野生蕈菌的驯化提供了理论依据。

The effects of Acremonium strictum on fruit-body formation ofPsilocybe venenata were studied. The results suggested that the interference competition existed between Psilocybe venenata and Acremonium stricture although such an interferent competition was weak. The macro-sporocarps, mini-sporocarps and atypical sporocarps of P venenata were formed on PDA plate and spent compost substrate. The polymorphism of the sporocarps of Psilocybe venenata, especially the formation of atypical ones may be the results of effects of Acremonium stricture. The study is helpful to the naturalization and further exploitation of Psilocybe venenata.
