Damage, symptoms and biology
Humicolous species that is 5 to 10 cm tall and measures 2 to 4 cm in diameter with a conical-shaped, sponge-like, brownish cap that presents several cavities arranged in vertical rows. The cap and the stem are separated by a very visible depression. The stem, slightly lighter in colour than the cap, is hollow, sometimes wrinkled and fairly fragile. The flesh is thin, fragile and has a very pleasant odour and taste. This species produces ochre-coloured spores.
Highly edible and sought after for its delicious flavour. It should be cooked carefully, however. The species' rarity has pushed up prices.
Habitats : deciduous forests, mixed forests, particularly those with balsam poplar.
