This southeastern species reminds me of a faded Suillus pictus or Suillus lakei. The cap is a dull pinkish orange, providing a subtle but attractive contrast with the yellow pore surface. Like its more brightly colored counterparts, Suillus decipiens has a dry cap--a welcome relief in a genus filled with slimeballs. Look for Suillus decipiens under pines (species of Pinus, with bundled needles) from New Jersey to Florida, and west to Texas.
Boletinus decipiens is a synonym. Suillus floridanus is a probable synonym.
