Observation 86057: Butyriboletus pulchriceps (Both, Bessette & R. Chapm.) K. Zhao, Z.L. Yang & Halling, comb. nov.

The very first bolete I found on my journey through the fungi world. After my father localized it under some bush, I picked it up and began to describe it as best as I could. Cap is primarily pinkish with pale yellow tones, not exactly smooth but not rough either. Tough and rubber-like, the flesh is firm and compact. The pore surface is a bright school-bus yellow which would most likely yield yellow spores (this specimen wasn’t quite mature yet). The stipe is amazingly enlarged from the middle to the base, and this is the only B. pulchriceps that I have seen in the area (or anywhere else, for that matter). In other words, it is capable of growing solitarily. Furthermore, the margin began to bruise green after at least 30 minutes, although not profoundly.

Found in coniferous woods that include ponderosa pine. This exact bolete was found underneath a tall bush in its leaf litter.

At the time, this was my first declared hunt for mushrooms BlueCanoe, and I was absolutely unknowledgeable when identifying mushrooms, much less the subrate or trees around it. This mushroom was found underneath some bush, actually, and the bush was near a tree. I known that in the region, Madera Canyon, this is a confierous wood with ponderosa pine, white pine, and limber pine. The altitude was 5,500 feet. Hope any of this helps, I can only wish that my IDing and notetaking skills were as good as they are today, as I would learn later that Boletus pulchriceps is rare. Oh well, I feel there’ll be more!

Any notes on the vegetation in the area? Particularly tree species? It would be great to add some ecological information to this observation since this species is not widely known.

Hahha I completely understand that feeling, Christian, and am grateful to be able to provide images of such an amazing and not well-known bolete. Feel free to check these out as well (courtesy of Arizona Mycota project): http://www.azfungi.org/...

Hope to find it in the same area this mushroom season to photograph it some more; two accurate results on Google images is downright sad.

I have been wanting to see this species since I first found out about it. Great find.
