Peronospora lotorum Sydow, 1923
Lotus spec., Belgium, prov. Limburg, Hasselt, Domein Kiewit © Carina Van Steenwinkel
conidiohpore with two spores
underside with a greyish-brown fungal down, consisting of 0.6 mm high erect conidiophores that apically several times are dichotomously branching, each terminal branch ending in am ovoid conidium.
Lotus alpinus, corniculatus, pedunculatus.
Sometimes the stem showed a strong swelling; also, within the stem sometimes a hypha seemed to be there. Probably this indicates hyperparasitation, perhaps by Cladospororium uredinicola, which is known also to parasitise on downy mildews.
swelling at the stem
