证据表明，在亚马逊雨林中的蚂蚁上发生冬虫夏草属动物流行病。一次暴发涉及2种新的冬虫夏草，C。kniphofioides和C. cucumispora）在黑胸蚁Cecumtes atratus上的分布。在一系列不相关的蚂蚁属上收集了形态相似的标本，但有足够的差异来保证分离：C。似刀叶藻似刀叶变种多利乔德里湾十一月，变种单酸变种十一月，变种马桑原变种11月]和C.黄瓜带孢变种黄瓜孢变种长角湾11月]被提议。从体内和体外研究中讨论了无性型协会。C. kiphofioides具有一个独特的无性型，具有2个分生孢子类型，容纳在被毛孢属的形式中。这就需要重新评估Synnematium Speare属，该属现在与Hirsutella同义。C. cucumispora是被毛孢属Hirsutella [H.卵孢霉属[ovalispora sp. nov.]。菌丝体的重要性进行了讨论，在有关的成功分离的冬虫夏草品种，并作为一种辅助诊断援助。
Evidence is presented for the occurrence of epizootics of Cordyceps species on ants in Amazonian rain forests. A single outbreak involving 2 new species of Cordyceps, C. kniphofioides and C. cucumispora, on the ant Cephalotes atratus is analyzed in detail. Morphologically similar specimens were collected on a range of unrelated ant genera, but there are sufficient differences to warrant separation: 4 varieties of C. kniphofioides [var. kniphofioides, var. dolichoderi var. nov., var. monacidis var. nov., var. ponerinarum var. nov.] and 2 of C. cucumispora [var. cucumispora, var. dolichodera var. nov.] are proposed. Anamorph associations are discussed from in vivo and in vitro studies. C. kniphofioides has a distinctive anamorph with 2 conidial types accommodated in the form-genus Hirsutella. This necessitated a re-evaluation of the genus Synnematium Speare which is now placed in synonymy with Hirsutella. The anamorph of C. cucumispora is a new species of Hirsutella [H. ovalispora sp. nov.]. The importance of hyphal bodies is discussed in relation to the successful isolation of Cordyceps species and as a supplementary diagnostic aid.
