Short-stemmed Slippery Jack

After months of drought we finally received a little rain. Unfortunately it was not much, but at least it brought out a few mushrooms. It has been a while since I saw fungi on my hikes.

The short-stemmed slippery jack (Suillus brevipes) is a bolete. Boletes have a cap and stalk but instead of gills possess a sponge-like layer of tubes on the underside of the cap. The spores are produced on the inner lining of the tubes and are released through pores.

Short-stemmed slippery jack, also commonly called short-stalked suillus, is a very common fungi found from the Pacific Northwest through California and on the East Coast west to Texas. It grows under conifers, particularly two and three needle pines.

Short-stemmed slippery jack has a smooth slimy cap that varies in color from vinaceous (wine red) to dark brown. With age this slippery jack gets lighter and can even appear brownish yellow. The flesh is white, the tubes are honey yellow and the stalk is solid and white. When bruised short-stemmed slippery jack does not turn blue.

If the leathery pellicle (skin) is peeled off, short-stemmed slippery jack is edible.

These short-stemmed slippery jack specimens were growing under ponderosa pines along Ash Creek (Lassen County CA).
