    • n apothecium In botany, the fruit of lichens, usually an open, rounded, shield- or dish-shaped body attached to the surface, as in gymnocarpous lichens, or globular and immersed in the substance of the thallus, as in the angiocarpous series of genera. An apothecium consists of an exciple and the included hymenium. The exciple is composed of a layer of cells (hypothecium) with or without an additional subhymenial layer. The hymenium consists of asci (otherwise thecæ or thekes), which are the sporebearing organs, usually intermingled with slender erect filaments (paraphyses).
