Hello,

it is definitly a rust fungus belongig to the genus Gymnosporangium. To distinguish the different species, mostly the pseudoperidia is very important. Macroscopic the length and microscopic the ornamentation of the cells of the pseudoperidia. Your last picture shows an irregular warty ornamentation of the wall. This is typical for Gymnosporangium clavariiforme.
