1823 G. Crabb Universal Technol. Dict. II. Peridium, a name given to the capsule of the mushroom, being a dry membranaceous hollow vessel filled with sporæ or gongyles.

1832 J. Lindley Introd. Bot. i. iii. 209 Peridium, is also a kind of covering of sporidia; peridiolum is its diminutive.

1861 R. Bentley Man. Bot. i. iv. 387 At other times, the hymenium, instead of exposing its sporiferous membrane to the air, as in Agaricus, &c., is enclosed in a leathery membrane called the peridium, as in Lycoperdon.

1929 J. C. Arthur et al. Plant Rusts i. 13 Less easily recognized as aecia, with spores borne singly on pedicels and usually without peridia or paraphyses, are the stylosporic or uredinoid aecia.

1950 L. E. Hawker Physiol. Fungi vi. 178 Hygroscopic movements of particular layers of the peridium play an important part in the exposure of the gleba of certain Gasteromycetes.

1998 New Phytologist 139 565/1 Tuber species are usually classified according to morphological features..such as..the structure of the peridium and gleba.
