Coniochaeta
genus of fungi
The Coniochaeta are a genus of pleomorphic yeasts of the order Coniochaetales and are pathogens of trees. 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. 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.
Ecology
The Coniochaeta have been described as typically associated with wood, water, and soil. 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.
Medical Issues
Other members of the Coniochaeta, most commonly Coniochaeta polymorpha, can cause clinical infections in immunocompromised individuals, which has increased recent interest in the genus.

“Coniochaeta” enters the record as genus of fungi. Crown Archives preserves that source wording while asking what Coniochaeta, genus and fungi can confirm, complicate or overturn.
Why this record matters
“Coniochaeta” is worth following because a concise public description often conceals a longer documentary argument. Here, Coniochaeta, genus and fungi provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 16, 2026. The linked authority identifier is Q10457878. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2013, 1887, 1971 and 1888.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
