  • Comments

    Suillus lakei is recognized by a reddish-brown, dry, fibrillose-scaly cap, pores that bruise brown, and a stipe base that turns blue when cut. Although the dry cap is somewhat atypical for a Suillus, it should be noted that old specimens of S. lakei may become viscid in moist weather, especially if the scales have weathered away. Suillus lakei var. pseudopictus occurs in Mendocino county and tends to have a darker, more fibrillose cap.
