Boeremia exigua
species of fungus
Boeremia exigua is the type species of the fungus genus, Boeremia, in the Didymellaceae family. It was first described as Phoma exigua by John Baptiste Henri Joseph Desmazières in 1849, and transferred to the genus, Boeremia, by M.M. Aveskamp, J. de Gruyter, J.H.C. Woudenberg, G.J.M. Verkley and P.W. Crous in 2010.
Desmazières describes the species as occurring on stems and dried leaves, with two varieties: one of which is found on the stems and leaves of a Polygonum species, and the other on the stems and leaves of Ranunculus.
It causes wet weather blight in cotton and it can be treated with systemic copper.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Boeremia exigua”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
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 Sep 16, 2026. The linked authority identifier is Q10432029. The first chronological checks are 1849 and 2010.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
