Boeremia exigua

provided by wikipedia EN

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. Aveskamp, J. de Gruyter, J.H.C. Woudenberg, G.J.M. Verkley and P.W. Crous in 2010.[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 Ranunculi.[3]

provided by wikipedia EN

Phoma exigua var. linicola is a fungal plant pathogen that affects flax.

The disease is passed on in the seed. The effects are more pronounced after the plant has flowered. Brown discolorations can be seen with small black dots, the pycnidia, where the spores are formed. The disease severely impacts the fiber quality.[1]
