Columella, a sterile tissue rising column-like in the midst of the capillitium, serving as a point of insertion for the threads which connect it with the peridium in the form of a net-work.
The peridiumis thin and delicate, breaking into fragments; creamy white in the young stage, and clothed with delicate warts, so minute as to give the surface a soft mealy appearance, the under surface somewhat plicate.
Capillitium sub-compact, equal, adnate to the peridium on all sides; spores pedicillate, brownish.
On the ripening of the spores this peridium ruptures, allowing their escape, the capillitium lending valuable aid in their dissemination.
In some instances theperidium is almost smooth, and sometimes cracks in areas, inner peridium thin and tough.
He does not regard them as genuine asci, but as corresponding more to the peridium of the Gasteromyceteae and Myxomyceteae.
The persistent warts which cover the surface of the peridium are so minute as to appear to the naked eye like scales.
The peridium is very fragile above, cracking into areae in the mature plant and breaking up and falling away in fragments, thus allowing the dispersion of the spores.
Peridium flaccid above, with mealy coating, obtuse, at length collapsing, the sterile stratum cellulose.
When the spores are mature, the peridium ruptures either by an external orifice, as in Geaster, Lycoperdon, &c.
E] Another order belonging to this sub-family is the Phalloidei, in which the volva or peridium is ruptured whilst the plant is still immature, and the hymenium when mature becomes deliquescent.
In the first place, we must recognize a small section in which a kind of cellular peridium is present.
In Onygenei, the receptacle is either club-shaped or somewhat globose, and the peridium is filled with branched threads, which produce asci of a very evanescent character, leaving the pulverulent sporidia to fill the central cavity.
In the former, the peridium is either single or double, occasionally borne on a stem, but usually sessile.
In this order the hymenium is at first enclosed within a sort of peridium or universal volva, maintaining a somewhat globose or egg-shape.
Gelatinous at first, peridiumcontaining at length a dusty mass of threads and spores Myxogastres.
This is a small but very curious group of fungi, in which the peridiumresembles a volva, which is more or less confluent with the surface of the pileus.
In Gasteromycetes, the second family, a true hymenium is also present, but instead of being exposed it is for a long time enclosed in an outer peridium or sac, until the spores are fully matured, or the fungus is beginning to decay.
The pustules, or sori, break through the cuticle in a similar manner, and here also no trueperidium is present.
The inner peridium is thin and fragile, after maturity breaking up into fragments, apparently without any subgleba; capillitium and spores yellowish-green to dingy-olive.
The peridium is obovoid, with a short base, the mycelium forming a cord like a root.
My attention was first attracted by some of the peridium shells upon the ground on Cemetery Hill.
Peridium large, obovoid or top-shaped, depressed above, with a stout thick base and a cord-like root.
The peridium is composed of two distinct layers, one called the cortex, the other the peridium proper.
Inner peridium membranaceous; dehiscent at the apex by a single mouth; columella none; threads of the capillitium very long, much branched and interwoven.
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.
Hymenium on the surface of the gleba which is enclosed within the peridium up to the maturity of the spores or longer; spores continuous, sphæroid or ellipsoid, hyaline or colored.
Plants membranaceous, leathery or fleshy, furnished with a peridiumand gleba, the latter being sometimes supported on a receptacle.
The plant at the extreme right is mature, and the inner peridium has ruptured at the apex to permit the escape of the spores.
Hymenium either free at the beginning, or enclosed either permanently or temporarily in a more or less perfect peridium or veil.
Varies to forms with single (inner) peridiumand simple physaroid capillitium.
The calcareous deposit on the peridium is usually very rich and under a lens appears made up of countless snowy or creamy flakes.
It is never crowded, shows no plasmodiocarpous tendencies, while the outer peridium is generally deciduous except at the base and falls in flakes.
The distinction between the upper and lower peridium would suggest Craterium, but the internal structure is not at all Craterium-like.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "peridium" in a variety of sentences. We hope that you will now be able to make sentences using this word.
