Traverso (1906) Phyllosticta sambuci Desm.

(1847) Boeremia exigua is the type species of the fungus genus, Boeremia, in the Didymellaceae family.

[1] It was first described as Phoma exigua by John Baptiste Henri Joseph Desmazières in 1849,[2][3] and transferred to the genus, Boeremia, by M.M.

[2][1] 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.

[3] It causes wet weather blight in cotton and it can be treated with systemic copper.
