uredospore

or

urediniospore

a BINUCLEATE rust-coloured SPORE produced by RUST FUNGI at a certain stage in the life cycle. Various spore stages have been defined; uredospores are formed in the summer and are the main dispersal agent of the rust Puccinia. The uredospore germinates to produce a binucleate MYCELIUM, from which new uredospores are produced.
