Herpomycetales
order of fungi
The Herpomycetales is an order of fungi within the class Laboulbeniomycetes. The order includes a single dioecious genus, Herpomyces, with 27 accepted species of obligate ectoparasites that are associated exclusively with cockroaches. Like the Laboulbeniales order, they produce cellular thalli. However, the thalli of Herpomyces are developmentally and morphologically unique.
The order was described in 2019 based on the phylogenetic analysis of three gene regions. A more recent phylogeny found that Herpomycetales and Laboulbeniales are not sister clades, which provides evidence for the idea that the thallus originated at least twice in the class Laboulbeniomycetes. This is in line with the fact that thalli of both orders are developmentally and morphologically different.
The draft genome of Herpomyces periplanetae has been sequenced and assembled—the only one in the class thus far. Herpomyces periplanetae is a very widespread parasite on the antennae of adult cockroaches in the genus Periplaneta, like the common American cockroach, Periplaneta americana.
This brief starts where responsible research should: with the source description of “Herpomycetales” as order of fungi. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as order of fungi. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 12, 2026. The linked authority identifier is Q60610511. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
