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

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

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.

<span class="mw-page-title-main">Hypocreales</span> Order of fungi

The Hypocreales are an order of fungi within the class Sordariomycetes. In 2008, it was estimated that it contained some 237 genera, and 2647 species in seven families. Since then, a considerable number of further taxa have been identified, including an additional family, the Stachybotryaceae. Wijayawardene et al. in 2020 added more families and genera to the order. According to the Catalog of Life, As of April 2021 the Hypocreales contains 6 families, 137 genera, and 1411 species. Hyde et al. (2020a) listed 14 families under Hypocreales, while, Wijayawardene et al. (2022) accepted 15 families in the order, where Cylindriaceae was additionally added. Earlier, Hyde et al. (2020a) had placed Cylindriaceae in class Xylariomycetidae. Samarakoon et al. (2022) agreed. Hence, Cylindriaceae should have been excluded from Hypocreales and placed in Xylariomycetidae. Xiao et al. (2022) recently introduced a new family Polycephalomycetaceae to Hypocreales.

Arachnomyces is a genus of cleistothecial ascomycete fungi described in 1902, of which the anamorph (asexual) stage is the genus Onychocola. Although morphologically similar to members of other families, the fungus now belongs to its own monotypic family Arachnomycetaceae, which is the only family in the monotypic order Arachnomycetales.
