Mallow Rust

Puccinia malvacearum is a rust fungus that galls the leaves and petioles of members of the Malvaceae family including Hollyhock and Mallows (such as Common Mallow).  There is no host alternation, and only telia are produced.  Numerous yellow spots occur on the upper surfaces of the leaves, whilst on the underside of the leaves and on the petioles it causes hard rounded swellings, occasionally yellowish but most often reddish brown and later powder grey.
