The opening of a peridium, when ripe, to discharge the spores.    From Wordnik.com.  [Among the Mushrooms A Guide For Beginners] Reference

The spores are released from the peridium and scattered by the wind or other factors.    From Wordnik.com.  [CreationWiki - Recent changes [en]] Reference

This name is given to the genus because of the hard peridium, the wall being much firmer and harder than in.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

The portion of the stalk that extends into the peridium (the capsule containing the spores) is the columella.    From Wordnik.com.  [CreationWiki - Recent changes [en]] Reference

Inside the peridium, spores are connected to the capillitium, a tiny, thread-like network the runs throughout the peridium.    From Wordnik.com.  [CreationWiki - Recent changes [en]] Reference

The plant at the extreme right is mature, and the inner peridium has ruptured at the apex to permit the escape of the spores.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

Hymenium either free at the beginning, or enclosed either permanently or temporarily in a more or less perfect peridium or veil.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

At maturity the wall, or peridium, breaks into brittle fragments, which disappear and the purplish mass of the spores is exposed.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

Plants membranaceous, leathery or fleshy, furnished with a peridium and gleba, the latter being sometimes supported on a receptacle.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

When the outer layer of the peridium splits, it does so by splitting from the base toward the apex, or from the apex toward the base.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

The wall, or peridium, is quite thick in the members of this genus, and when it matures it separates into several layers which need not all be discussed here.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

The outer part of the wall (outer peridium) when quite young separates into warts or scales of varying size, large ones arranged quite regularly with smaller ones between.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

These warts are well shown in the two plants at the left in Fig. 210, and the third plant from the left shows the reticulations formed of numerous scars on the inner peridium where the larger scales have fallen away.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

Hymenium, at the beginning, borne on the free outer surface of the compound sporophore, or if at first enclosed by a pseudo-peridium or veil it soon becomes exposed before the maturity of the spores; mushrooms, etc. HYMENOMYCETES.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

At this stage the plant is a very beautiful object with the crown of vermilion strips radiating outward from the base of the fruit body at the top of the stem, and the inner peridium resting in the center and terminated by the four to seven teeth with vermilion edges.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

When mature the base or stem, which is formed of reticulated and anastomosing cords, elongates and lifts the rounded or oval fruiting portion to some distance above the surface of the ground, when the gelatinous volva ruptures and falls to the ground or partly clings to the stem, exposing the peridium, the outer portion of which then splits in the manner described.    From Wordnik.com.  [Studies of American Fungi. Mushrooms, Edible, Poisonous, etc.] Reference

(peridium), as in the Puff-balls, but they are contained in delicate sacs on the cap.    From Wordnik.com.  [Among the Mushrooms A Guide For Beginners] Reference

Bird’s-nest fungi from others consists in the fact that the spores are produced in small envelopes that do not split open, and which are enclosed in a common covering, called the peridium.    From Wordnik.com.  [Among the Mushrooms A Guide For Beginners] Reference
