Excerpt from British Basidiomycetae: A Handbook to the Larger British FungiThe sporophore is of different shapes, e.g. Globose as in puff balls, sessile with outstretched ¿aps as in Stereum, erect, clavate, coralloid or dendroid as in Clavaria, or differentiated into dis tinct stem, pileus or cap and hymenium-bearing surface as in the mushroom. When young the sporophore is often completely surrounded by a universal veil or membrane termed the volva which is ruptured by the growth of the stem and in many species portions or traces of this remain permanently at the base of the stem. A second membrane or partial veil consisting of either interwoven or arachnoid threads often protects the hymenial surface before it is mature and extends from the stem to the margin of the pileus: it either disappears completely or remains as a ring on the stem, or in appendiculate fragments at the margin of the pileus. The wall surrounding the Gasteromycetae is termed the peridium and consists of one, two, or more layers, the exoperidium to the exterior and the endogaeridium to the interior. The peridium sometimes incloses separate hymenium bearing bodies, the peridiola, which are either free, attached by a cord funiculus) or form a compound structure. The contents of the peridium are collectively known as the gleba, in addition to spores there are often certain threads, the capillitium, which arise either directly from the base, from the walls of the peridium or are attached to a denser central portion, the columella.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
