Observation 12670: Leccinum vulpinum Watling
When: 2008-10-09
No herbarium specimen

Notes: Under one of those “super” pines there was a rather large bolete, as big around as a tea-saucer or a bit more, accompanied by a smaller one of the same species.

First two photos show the larger mushroom on the ninth. Next two are increasingly wide-angle, and the smaller one is visible. Next three are the smaller one, which I photographed close-up, then uprooted and photographed two more times on the ninth. Eighth photo is the larger mushroom on the fifteenth. Its pores had darkened and it generally looked the worse for wear.

The “super” pine has a different pattern of growth, and is spiderier, than the dominant pine species of the main woods. I had a close look at both types of pine and determined that the “super” pine is a 2-needle pine and the more usual pine is a 5-needle pine. Is there a strong association between 2-needle pines, specifically, and symbiotic fungi?

NA Leccinum mess

Irene, you are probably right about it being L. velpinum. Although in North American we still incorrectly call stuff growing with pines (and aspen & birch) L. aurantiacum, never mind the fact that it probably doesn’t even occur here.

would have been my suggestion, if it hadn’t been for all the other Leccinum species described from North America.. It’s growing with pine, has a reddish brown cap with overhanging flaps at the margin, dark reddish brown to almost black scabers, only slightly blueing (the colour change is weak and slow and not really blue, rather violet to gray).
L. aurantiacum is a name that seems to represent several other species that grow with hardwoods.

About 5-needle pines, I’m not sure about Leccinum, but I know at least one bolete that grows exclusively with those: Suillus placidus, and I’m sure there are other examples too.
