Very rare; Shere, near Guildford, October, 1865 (Dr Capron). This species has been found only once in England. Desmaziferes who records it on Tropaeolum minus, in August, says that it causes, on the upper face of the leaf, numerous irregular spots, barely 1 mm. across. It has been recorded from France and Belgium. .^cidium Hellebori Fischer. JE. Hellehori Fischer, Ured. Schweiz, p. 526. Spennogones.
