Observation 150958: Suillus luteus (L.) Roussel
When: 2013-10-31
No herbarium specimen

Notes: Growing gregariously under mature white pines. Interestingly, all specimens (~ a dozen) had stubby stipes. The veil covered the mushrooms from the root of the stipe to the cap margin. Peeling the veil away revealed a pale yellow stipe with a mixture of glandular dots (at the apex) and soft “scabers” (see middle picture).
Despite the fact that Slippery Jack is allegedly a very common mushroom, this is actually my first time encountering it. Also, we apparently found it only a couple of times during our NJMA forays (since 2007). Maybe it’s not very common in the Garden State after all…
