SummaryRust fungi are important components of ecological communities and in ecosystem function. Their unique life strategies as biotrophic pathogens with complicated life cycles could make them vulnerable to global environmental change. While there are gaps in our knowledge, especially in natural plant–rust systems, this review of the exposure of rust ...

Rust fungi (Basidiomycota; Order Uredinales) belong to the largest groups of fungi, with more than 6000 recognized species. Rust diseases have accompanied human history from the beginning of agriculture in the Fertile Crescent and Central America, by threatening the health and productivity of the earliest cereal (wheat, barley, maize) and legume (pea ...

Aecidium fragiforme &A. balansae, parasites ofAgathis spp. in the Malay Archipelago and New Caledonia, respectively, are similar but separate species. They differ from all other confier-infecting rust fungi in having intra-epidermal spermogonia, and from nearly all others in having cupulate aecia.Caeoma sanctae-crucis onAraucaria in Chile has unique ...

THE INFLUENCE OF ANTAGONISTIC FUNGI ON THE SPORE FORMATION OF RUST FUNGI
1979Abstract Organic extracts from fungus-free filtrate of Aphanocladium album -cultures induce teliospore-formation on rusts: Puccinia graminis f.sp. tritici , P. dispersa , P. striiformis and P. sorghi formed premature telia on plants treated with the extracts.

This paper tries to illuminate the current terminology of the spore forms of rust fungi. It is shown that the widespread adoption in America and elsewhere of the ontogenic approach to terminology is fundamentally illogical and causes difficulty and confusion.

The native rust fungi of Hawaii
Canadian Journal of Botany, 1994F.L. Stevens (1925. Bernice P. Bishop Mus. Bull. No. 19) published the first comprehensive list of fungi in Hawaii, recognizing 7 species of endemic rusts and 10 species probably indigenous. Stevens considered this small number of rusts particularly noteworthy in comparison with the rust floras of other areas with which he was familiar.
