What You Should Know
Lepiota ignivolvata is a rare member of the gilled mushroom genus Lepiota. It is among the larger species in this group, growing in coniferous or deciduous woodland during autumn; it has a primarily European distribution. The center of the cap is reddish-brown, or orange-brown, breaking into small scales, which are fewer, and lighter towards the margin. The best identification aid is the orange (somewhat indented) ring, which is low on the white, slightly bulbous to club-shaped stem, which often has an orange flush at its base.
This mushroom is inedible, and perhaps poisonous, it should not be gathered for culinary use. Many of the species in this genus are deadly.
Other names: Orange-girdled Parasol.

Lepiota ignivolvata Taxonomy and Etymology
The basionym of this species dates from as recently as 1948, when French mycologists M. Bousset and Marcel Josserand (1900 - 1992) described this dapperling and gave it the binomial scientific name Lepiota ignivolvata by which it is still generally known today.
Lepiota, the genus name, comes from the Latin word lepis, meaning scale, and is a reference to the scaly surfaces of caps of members of this group of agarics.
The specific epithet ignivolvata means 'wrapped with fire' - a reference to the orange (flame-colored) band in the center of the stem ring.
