Puccinia is a genus of fungi. All species in this genus are obligate plant pathogens and are known as rusts ^[1].

Examples of Puccinia rusts and the diseases they cause:

• Puccinia asparagi - Asparagus rust
• Puccinia graminis - Stem rust, also known as black rust
• Puccinia horiana - Chrysanthemum white rust
• Puccinia poarum - Coltsfoot rust gall
• Puccinia psidii - Guava rust or eucalyptus rust
• Puccinia recondita - Brown rust
• Puccinia sessilis - Arum rust and Ransoms rust
• Puccinia striiformis - Stripe rust, also known as yellow rust
• Puccinia triticina - Wheat leaf rust, also known as brown rust

The rust species Puccinia obtegens has shown some promise for controlling Canada thistle, but it must be used in conjunction with other control measures to be effective ^[2].
