The Coniochaeta are a genus of pleomorphic yeasts of the order Coniochaetales and are pathogens of trees.[1] Some species have also been found to form endophytic associations within plants in which they live inside plant tissues but do not actually harm the organism.[2] They can take the form of pink to brown colonies, hyphae, conidiophores or sclerotia. In 2013, the Lecythophora were merged with the Coniochaeta, following suggestions by Ziauddin Khan et al.[3]

Ecology edit

The Coniochaeta have been described as typically associated with wood, water, and soil.[4][5] 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.[6]

Medical Issues edit

Other members of the Coniochaeta, most commonly Coniochaeta polymorpha, can cause clinical infections in immunocompromised individuals,[3] which has increased recent interest in the genus.
