Pinus contorta
"Lentinellus montanus" is a white rot fungus. Its fruit bodies grow singly, or, more commonly, in clusters on decaying conifer wood at elevations between . Recorded tree substrates include Engelmann spruce ("Picea engelmannii"), Shasta red fir ("Abies magnifica" var. "shastensis"), subalpine fir ("Abies lasiocarpa"), and "Pinus contorta". The fungus mycelium has also been found growing on fire wounds on living trees of Engelmann spruce and Lodgepole pine ("Pinus contorta"), where it attacks the springwood and causes small pockets of rot.
