Chrysomyxa Diebuensis
''Chrysomyxa'' is a genus of rust fungi in the family Coleosporiaceae. The genus, widespread in the Northern Hemisphere, contains about 23 species. Rust fungi in the genus ''Chrysomyxa'' occur in boreal forests of the northern hemisphere on Pinaceae, (mostly ''Picea''), and most species alternate to angiosperm hosts in the Ericaceae.Crane, P.E. 2001.

Chrysomyxa Rhododendri
''Chrysomyxa ledi'' var. ''rhododendri'' is a plant pathogen responsible for the disease spruce needle rust. It is present in European mountains, and especially in Switzerland in Grisons and Ticino between 1,000 and 2,000 metres. The spores of the fungus hibernate on ''Rhododendron'' species. In spring and summer, it migrates to spruce and infects recently emerged needles, coloring them in yellow Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the R .... In autumn, the spores that developed on spruce infects the rhododendron again. References Fungal plant pathogens and diseases Fungi described in 1815 ledi var. rhododendri {{Teliomycotina-stub ...
