The cap is egg-shaped at first, from which then emerges a stem topped by a cone-shaped honeycombed head truncated by a small hole, spongy/honeycombed, covered with a gelatinous dark brown-olive layer, later disappearing to leave a-white honeycombed head, with a clearly marked stem, long and cylindrical, white, spongy and slightly honeycombed, emerging from a white sac (volva) and attached to the ground by a mycelial strand.

The flesh is white, fragile and brittle; its taste is pleasant, nutty (stem); the odour is extremely strong, of rotting flesh, that can be smelt from at least 15 feet away.

The fertile surface is composed of a stinking dark olive slime. The spore print is olive green.

It grows on the ground, in coniferous or deciduous woods, parks and gardens, on a rather variable soil.

The fruiting period takes place from May to December.
