Rhabdocline pseudotsugae

''Rhabdocline pseudotsugae'' is a fungal plant pathogen. The pathogen, along with ''Rhabdocline weirii'' causes Rhabdocline needlecast; ''R. weirii'' only affects Douglas-fir trees. The disease causes the needles of the tree to discolor and eventually fall from the tree. It was originally common to the Rocky Mountain states of the United States but has since spread to Europe. Infections usually start in the spring or early summer and can change the color of the foliage to a variety of hues. The fungus produces apothecia that are normally found on the underside of needles but they also occur on the topside as well.
==Range==
Originally common in the Rocky Mountain States, the fungi spread to the Northeastern United States on ornamental forms of fir trees planted there. It has spread to Europe on trees imported from western North America and it is causing problems with trees growing there also.〔Westcott, Cynthia, and R. Kenneth Horst. 1979.
