Observation 53020: Suillus granulatus (L.) Roussel
When: 2010-09-15
(45.806412° -77.136941° )
No herbarium specimen

Notes: In Zone 43 (moss, jack pine).

Both locations where this is common (Zones 15 and 43) have both moss and jack pine. Areas with jack pine but little moss (e.g. Zone 38) or with the moss but little jack pine (Zones 19 and 39) have little or no S. granulatus. So it looks like it may be MR with Pinus banksiana and also has some dependency on the moss.

This specific kind of moss, and none of the several others I’ve seen, seems to be required for several distinct mushroom species — at minimum, S. granulatus, Cantharellula umbonata, Rickenella fibula, an unidentified Mycena sp., and an all-yellow Dermocybe, if not more.

This, too, must be a symbiosis, but I’ve not heard of mosses being MR. Probably the symbiosis is of a different sort. Has anyone studied it extensively?
