Puccinia malvacearum Bertero ex Mont. 1852
This fungus is widely distributed and causes a rust disease on Malva as well as other Malvaceae. Brown to reddish-brown telia are formed on the lower side of the leaves with elongated teliospores, around 40-70 x 20 µm long attached to a hyaline pedicel. The teliospores germinate to form basiospores. Aecia and uredinia are not produced. The fungus overwinters on plant debris.
