Short-stalked Suillus

Also known as Stubby-stalk, Short-stemmed Slippery Jack

Short-stalked Suillus forms vital mycorrhizal partnerships with two- and three-needle pines across North America, wrapping dense fungal sheaths around tree roots to trade soil minerals for plant sugars. Fruiting typically peaks in late summer and autumn after soaking rains, producing thick-fleshed mushrooms with distinctly glutinous caps that help prevent desiccation in dry pine duff. Unlike many relatives in its genus, it lacks both a membranous stem ring and prominent dark glandular dots along its stalk.
