Hypomyces luteovirens

Normally, the gills and stem of this Russula mushroom are white, but this
collection has been attacked by the parasitic fungus Hypomyces luteovirens.

This microscope image shows the perithecia (tiny fruiting bodies)
of Hypomyces luteovirens that contain the spore producing cells.
