Appendages numerous, attached on and below the equator. They are up to 2 x as long as the diameter, flaccid, hyaline, septate, generally unbranched.

notes

For a long time each Golovinomyces occurring on Boraginaceae was considered one species, Golovinomyces cynoglossi. However, a study by Braun, Bradshaw, Zhao ao (2018a) demonstrated that at least three species are involved: G. cynoglossi on Cynoglossum, G. asperifolii and Buglossoides, Echium en Myosotis, and G. asperifoliorum on Pulmonaria and Symphytum. The parasites of the many other genera in this family provisionally are addressed as “Golovinomyces cynoglossi complex”.
