peridium

In other words, the peridium leaves the stipe some distance below the point where the lowest capillitial branches take origin.

Rostafinski distinguished this beautiful species by the color of the peridium and the conic columella.

The persistent base of the peridium is also characteristic, very prominent sometimes, and visible to the naked eye.

The outer peridium is deciduous, and the inner slowly ruptures, by irregular fissures discharging the spores.

Sporangia; the first with the outer peridium broken away, 10.
