Telium

Front

- Formed from Urediniospores - Produces teliospores

Back

Info

Back

Urediniospore

Front

- Forms from uredinium - Can be made while wheat is growing - Can inhibit grain production - Produces telium

Uredinium

Front

- Forms from aeciospores - Dikaryotic mycelium forms these - Creates urediniospores - Is the asexual? life cycle
