Coniochaeta

The Coniochaeta form a genus of pleomorphic yeasts of the order Coniochaetales and are pathogens of trees.[1] They can take the form of pink to brown colonies, hyphae, condiophores or sclerotia. In 2013, the Lecythophora were merged with the Coniochaeta, following suggestions by Ziauddin Khan et al.[2]

Ecology

The Coniochaeta have been described as typically associated with wood, water, soil,.[3][4] However, there is also growing evidence of specialised associations between each species and specific environments, and a suggestion that 4-spored and 8-spored species interact differently with their environments, some species surviving forest fires, which activate their sexual cycle.[5] Other members of the Coniochaeta, most commonly Coniochaeta polymorpha, can cause clinical infections in immunocompromised individuals,[2] which has increased recent interest in the genus.
