When: 2015-10-02

Notes: Mossy boggy area with several types of birch.

KOH reaction does not match what is reported in BRB for holopus var. americanus, but everything else matches very well.

Dave,
Yes, just south of the rifle shooting range and on the west side of Suscon Road. There is a small parking area, and a trail that leads far into a larch bog. I have only walked a couple of miles in myself. We saw many Suillus and a few Leccinum specimens there in early/mid October. Many signs of bear as well!

Thanks for the reply, Jeff.

Despite SGL being close to spots I often visit, I have not explored this area. Sounds like an interesting habitat for mushroom diversity. Is this the area east of Suscon Road?

Dave, my mistake.

Yes I meant PA SGL 91, and did not see this reply until now. My apologies!

Jeff, do you mean…

PA SGL 91? Game Lands 92 appears on Google Maps in Sullivan County.

I observed many of these in SGL 92 just to the NNW of your area on 10/11/2015 in a larch/birch/cranberry bog.

Too bad you cannot make it, Dave

Yes, I will mention your scaber-stalk collection to Michael. I have a few sample of my own to give him, too.

I too have

mentions two varieties of holopus… a non-staining var. holopus and a pink staining var. americanum.

I’ve got company visiting over the weekend.

So I won’t be able to attend Michael Kuo’s talk. Could you mention to him that I have another substantial collection of Leccinum material to send to him?

Is not that

a synonum of Leccinum holopus?

Nice collection, Dave

Judging from the fact that there are only 8 obs for this mushroom, half of which come from your area, it’s a seldom encountered entity. On the other hand, BRB lists it as “fairly common”. Go figure… Theoretically, one should expect it to grow in extreme NW New Jersey, like in Stokes S.F., in wet Betula woods, but I don’t recall ever seeing it there. According to the NJMA species list, this bolete was found only once in the last 33 years, and it was probably a misidentification… Are you coming to M. Kuo’s lecture on Sunday?
