Abstract
The fungus Rhabdocline pseudotsugae Syd. on Pseudotsuga douglasii Carr. and Ps. glauca. Mayr. was studied in detail.
The fungus is biotrophic. Invaded cells remain intact. Flecking of the needles occurred after winter killing of invaded host cells. Apothecia on diseased needles were only formed when needles remained attached to plant.
Resistant or partially resistant trees were found. The disease was widely dispersed by selling young plants infected in the nursery.
