SUILLUS: 'Pig Mushrooms

  Many have tacky, viscid and/or slimy caps; glandular dots on stipe; white to yellow tubes; fine round to angular and radial pores. A few have dry, fribrillose caps and stems. Some have a partial veil and leave remnants on their margins and/or a ring on the stipe. Most are mycorrhizal with conifers and some with broadleaf trees.
