where can I find sites or documents about spores (aeciospores, teliospores or uredospores) of Pucciniaceae, especially the genus Gymnosporangium ? many thnaks
Cedar–apple rust is caused by the fungus Gymnosporangium juniperi-virginianae. Similar diseases with hawthorn and quince as alternate hosts are caused by two other species of fungi in this genus. G. globosum and G. clavipes, respectively.
