Cedar-apple Rust (by me)
Tranzschelia pruni-spinosae -fungus causing rust disease symptoms on the leaves of a plum tree (Prunus domestica). Plenty of asexual urediospores are seen in the pictures taken with a microscope.
Urediniospores of Phragmidium mucronatum, causing rust disease on Rosa mollis.
