Sell, Indrek. Taxonomy of the species in the Phellinus igniarius group. Mycotaxon 104: 337–347. 2008.

ABSTRACT:   Differences between the species of the Phellinus igniarius complex are characterized using morphological and molecular analysis. The study focuses on the possibly new taxa collected from ashes (Fraxinus), maples (Acer) and oaks (Quercus). It is shown that the species growing on ashes and maples belong to Phellinus alni. The situation regarding Phellinus found on oaks is unclear: that material belongs to Phellinus alni genetically but differs somewhat in its micromorphology.
