De B<iiyhas described the complex peridiumof Geaster in the following terms:— Geaster hygrometricus is up to theperiod of perfect maturity a roundishbody, which may be of the size of ahazel-nut, and remains beneath the surface of the layers may be distinguished in the peridium in a verticallongitudinal section a sliort time before the compound sporo-phore is mature (Fig. 66). The outermost layer is of a brownishcolour, flaky and fibrous, and is continued on one side into themycelial strands which spread through the soil, and on theother passes into the second layer; a thick, stout, brownmembrane entirely covering the compound sp
