It is a large mushroom with a greasy to tacky, bald, brown cap and a meaty, swollen stem that features fine reticulation. The pore surface is initially white, with "stuffed" pores but as the mushroom matures the pores become more visible and the pore surface becomes greenish yellow. The flesh does not change color when the mushroom is sliced, and its surfaces do not bruise on handling.
Convex, flattening. Fawn to a dull light brown. Margin smooth. Surface smooth and dry initially, becoming greasy with age. In wet weather, becoming slightly viscid and shiny.
70mm-19mm long x 15mm-55mm at apex, swelling towards base. White reticulations on a fawn background. Ring absent
Grows in woods
This fungus is perhaps the most important edible species, it can often be found on sale in continental markets. Commercially it is dried and used as flavouring for soups.
