To be quite honest, I am uncertain as to what the agent is, that is causing the leaf spots on Tolmiea menziesii here. I have read of two species of Colletotrichum in the USA that cause similar symptoms of disease, in plants grown in the USA for domestic use. Of those two diseases only one occurs on the UK fungi checklist, and that is Colletotrichum acutatum. So please only accept this species of fungi as being possible for this plant.

I'd be keen to hear from anyone who knows this disease in the USA.

The Tolmiea menziesii here was found at the north end of Drift Reservoir, south of Skimmel Bridge, Sancreed, near Penzance, Cornwall. 30.09.13.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. The difference between species is rarely obvious, many species can only be determined by observing microscopic characteristics that are specific to any one species.
