The report of these fungi from the plants of Silene cholorifolia, Dianthus macranthoides, Silene casarea, Achilea tenuifolia, Seratula cerintifolia, Scariola orientalis, Teuchrium orientale, Salvia multicaulis, Eryngium noeanum and Euphorbia virgata, the first report of the world, and the reported fungus from Pterocephalus plumosus is the second report from the world and the reported fungus on Myositis palustris host is the first report from Asia and Iran.
