Golovinomyces sonchicola

Description

Golovinomyces sonchicola is a powdery mildew, parasitic on various species of Sow-thistle. It forms irregular patches on leaves and stems and not infrequently coats entire leaves and seriously reduces the vigour of the host plant. Smooth Sow-thistle (Sonchus oleraceus) seems particularly susceptible. 

Identification difficulty
Recording advice

Detailed microscopic examination is necessary for all records.

Habitat

Wherever the host Sow-thistles occur.

When to see it

Whenever the host species are in leaf, particularly in warm, dry periods of late summer when the fungus is often particularly conspicuous.

UK Status

True status in Britain is difficult to determine due to lack of records, although it would seem occur fairly frequently.

VC55 Status

Status in Leicestershire and Rutland not known.
