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.

Uredinia are observed initially in the dark dots that progressively acquire a light brown to red brown color and open in a minute pore releasing the colorless urediniospores, which become tan and accumulate around the pores (Balardin, 2002; Yorinori et al., 2004; Almeida et al., 2005).
