glutinous Gomphidius, hideous Gomphidius, slimy Gomphidius, slimy spike

Conservation Status: Not of concern

Identification Notes:

Both this species and Gomphidius subroseus are typical members of Gomphidius, with viscid caps, waxy decurrent gills, black spores, soft flesh, and yellow stipe bases. G. glutinosus is larger (cap diameter up to 10 cm or larger) and duller colored, with a cap that is purplish gray to purplish brown when young. G. subroseus is usually somewhat smaller (maximum cap diameter only about 7 cm) and has a pinkish to sordid reddish cap. Both occur commonly with Douglas-fir, but may associate with other conifers as well. A handful of other species occur in the PNW. G. maculatus is similar in size to G. subroseus but has a light cinnamon to reddish brown cap, develops black stains on the stipe and cap in age, and is associated with larch. G. oregonensis is very similar to G. glutinosus and occurs in the same habitats, but has smaller spores (10--13 µm in length vs. 15--21 µm) and tends to grow in clusters of several mushrooms. The rarely reported G. smithii has a grayish red cap, pinkish flesh in the lower stipe, and the stipe blackens when handled.
