Onnia tomentosa is a species of fungus in the family Hymenochaetaceae commonly known as the woolly velvet polypore. It is frequently found in coniferous forests at higher altitudes, often growing in large groups, rather rare at lower altitudes. It is a plant pathogen, and causes tomentosus root rot, primarily in spruce. It was formerly known as Inonotus tomentosum (Fr.) Teng until molecular phylogenetic analysis led to major revisions in the classification of the Hymenochaetaceae.
