False-colour scanning electron micrograph of the interior of the edible mushroom Coprinus dissemin- atus,commonly known as the crumble cap. The visible mushroom is a "fruit body" which appears only after years of growth of the fungus in the soil. The fruit body produces millions of special cells called basidia from a surface layer known as the hymenium. In this micrograph,the basidia are the elliptical cells at top; at bottom is the hymenial layer in cross-section. Sexual union occurs in the basidia,& results in formation of small cells,or basidiospores,which are released & dispersed by air currents to found new colonies of the fungus. Magnification: x680 at 35mm size. Yellow tint. Ref.: MICROCOSMOS,figure 5.36,page 106 | |
