This incredible mushroom is found almost exclusively on the wood of eastern hemlocks, and its range parallels that of the tree: northern and montane areas east of the Rocky Mountains. It is one of the “laccate” species of Ganoderma, which means it features a beautifully lacquered-looking cap surface. Like other species of Ganoderma its pore surface bruises brown and its spores have double walls with a chambered appearance.
Ganoderma oregonense is a similar species found in the Pacific Northwest and California on the wood of various conifers; it features larger spores. Until recently Ganoderma oregonense and Ganoderma tsugae were thought to coexist in the Pacific Northwest, but recent study of hundreds of North American Ganoderma collections by Loyd and collaborators (2017, 2018) failed to support this idea.
