Golovinomyces hydrophyllacearum (Braun) Heluta, 1988
on Nemophila, Phacelia
notes
mycelium amphigenous, almost persistent. Conidia in chains, elliptic, without fibrosin bodies. Cleistothecia with 6-15 asci that contain 2 (rarely 3) spores. Appendages numerous, attached on and above the equator, 1-3.5 x the diameter; they are rather stiff and straight, unbranched, septate, brown for much of their length.
hostplants
Boraginaceae, oligophagous
Nemophila menziesii; Phacelia.
notes
North American species, in Europe known only from the ornamental Nemophila menziesii. Phacelia, that is much used in Europe because of its nectar production, is still a potential host plant.
