now has an addition to the milk thistle seed and New Zealand Jade I carry into the woods. Thanks so much for the ID Daniel.
I most often find it on pine, typically Poderosa. But it also grows on larch sometimes. I strongly suspect old-growth Douglas-fir at higher elevations, too. Usually the tree has to be 6 feet diameter breast height for this species to be viable.
I’m not as certain whether this is a heart-wood rotter. Typically it is seen growing on the outside of the trunk. But Laetiporus sulphureus is likely a heartwood degrader too, but fruits on the outside of the trunk. Experimentation will have to wait. Most of our conifers locally have little available heartwood until the trees are over 60 years of age.
In Europe it’s restricted to larch in high altitudes and considered very rare. Yes, it is of medical value, hence the epitheton “officinalis”.
Sampled dried material. Held in my mouth for about 25 seconds. Distinctive taste/bitterness of quinine. Arora notes it is called Quinine conk. Only Fomitopsis to have that bitter quinine taste. BTW, said to be medicinal.
Fairly sure this is F. officinalis, although very young. Looks to be growing from heartwood – a good sign. Usually grows on Pinus in my area, and is often massive.
