a further contribution to the knowledge of sooty mould fungi from iran

sooty mold fungi are often associated with honeydew which insects secrete while feeding on the plant. a great variety of these fungi occur in the north of iran, especially on citrus ssp which is one of the most widely cultivated fruit trees in this region. during last 10 years, several collections of these fungi examined and 15 species have been recorded. in this paper seven previously unreported species are treated and described for the first time from iran. the treated species include catenuloxyphium heterosporum (on salix aegiptiaca and alnus glutinosa); echinothecium sp. (on eriobotrya japonica and passiflora sp.); cf. denisiella sp. (on citrus sinensis and malus pumila); fumagospora capnodioides (on alnus glutinosa, populus deltoids, salix aegyptiaca and zelkova carpinifolia); leptoxyphium fumago (on alnus glutinosa, rubus sp. and phytolacca americana); tripospermum juglandis (on ligustrum sp.) and scorias spongiosa (on citrus sinensis).
