I’ve been finding this strange-looking Suillus sp. a few times at FFP from late July. They’ve been growing in wet areas in different part of the preserve. The overall stature (small habit, tapering down stipe and decurrent hymenium) and the highly elaborate structure of the hymenophore (radially arranged, large, angular and compound pores with internal cross-veins) is very reminiscent of the mushroom that used to be called Fuscoboletinus paluster. However, the drab and pallid colors of this mushroom, as I always found it, don’t support the above species concept.

Ammonia on cap was negative, but readily stained the exposed tissue pink. KOH produced a faint gray-brown reaction with the pileipellis and stained the flesh blue green.

Pine Barrens Conifers

I know I should have paid attention to what trees I collected these under. By and large, the NJ Pine Barrens are dominated by Pinus rigida and isolated stands of the Atlantic white cedar. I also think that there are smatterings of Pinus stobus here and there, but I belive they have been planted. I believe that Larix laricina is quite rare in the NJ coastal plain. According to wikipedia, its extreme southeastern range exends only to northwestern NJ. It’s difficult to keep track of conifers especially when you are surrounded almost exclusively by the pitch pine.

Unfortunately, I didn’t take a spore print.

What types of conifers do you have?

Is there larch in area where you collect it? If not what are the pines? and did you try a spore print?
