Suillus caerulescens  Smith & Thiers (1964)                                                 *Collections: Calfiornia

This species is a staple of the coastal forests of Northern California. It is by far the most abundant Suillus in the area and thought to be associated with Douglas Fir. I see it fruiting from November to as late as June. Similar species, but with a distinct thick, orange belt on the stipe is Suillus ponderosus.

Blue reaction, typically in the lower stipe Brownish bruising reaction on the sponge
