Haustoria of the haploid stage (n stage) of Cronartium ribicola in bark cells of Pinus monticola were studied with the aid of the scanning electron microscope. The morphology of mature haustoria in all kinds of bark cells was consistently filamentous or elongate (hyphalike). Only immature haustoria are short and globose or reniform. Immature and mature haustoria are constricted at the point of passage through the host cell wall. N stage C. ribicola hyphae are characterized as having haustoria that are morphologically similar to intercellular hyphae.
