[edit] Development
Urediniospores develop in the uredium at the bottom of a leaf's surface.
[edit] Morphology
- Urediniospores are usually consist of two dikaryote nuclei within one constricted cell resembling the number 8 without a septation. As the spores germinate, the nuclei undergo karyogamy and thereafter meiosis, giving rise to four-celled basidia with haploid basidiospores.
- They don't have a thick-capped telia as compared to teliospores.
- Looks like a balloon pinched in the middle, (like an 8 without septation)
