Summary: Naohidemyces is included as an example of the Uredinales (rust fungi). The rust fungi all grow on vascular plants, and often have very narrow host ranges. They do not have basidium producing fruitbodies, because basidia are produced from overwintering spores. There are up to five different types of spores specialized for different parts of the life cycle, and often two separate hosts that are taxonomically unrelated to each other. Naohidemyces vaccinii in BC has hemlock as one host (the aecial host), and the other host (the telial host) is blueberry, huckleberry, dwarf bilberry, grouseberry, or lingonberry.
Microscopic: spermogonia on the underside of needles, subcuticular, without bounding structure, 80-150 microns in diameter and up to 70 microns high
Notes: not specified but includes BC
Habitat and Range
SIMILAR SPECIES
Another needle rust, Melampsora epitea is also found on hemlock. ''The aecia of M. epitea are "loose", with no peridium covering the aeciospores, while those of N. vaccinii have a dome-shaped covering with a centrally located hole (ostiole) through which the spores are released.''
