Suillus luteus or ‘Slippery Jack’ mushrooms are common in our local pine forests.
Suillus luteus or ‘Slippery Jack’
Slippery Jacks belong to the Suillaceae family. They are classed as boletes, which have pores under their cap rather than gills.
ECOLOGY: Introduced species. Mycorrhizal with exotic conifers. (Including pines such as Pinus radiata.)
CAP: 5-12cm in diameter. Convex, becoming broadly convex-flat with maturity. Dark brown, reddish brown or yellowish brown in colour with a slimy texture when wet.
PORES: Pale yellow, becoming darker yellow – olive yellow with maturity.
STEM: Up to 8cm length. White – brown veil which also has a slimy texture when wet. Small, light brown dots above the veil.
SPORE PRINT: Brown
EDIBILITY: Edible. Best to use dehydrated and added to soups or stews. sautéeing may cause the mushroom to collapse and turn into an unpleasant, gelatinous mess.
OTHER NOTES: Suillus granulatus is also referred to as ‘Slippery Jack’ and is also edible. Identifying features are very similar to S.luteus but S. granulatus lacks a veil.
