The capillitium becomes segmented through white to yellowish, partly perforated limestone plates, which are overgrown on the edge of the peridium.

The formation of calcium oxalate crystals stretches the layers of the outer walls, pushing the inner and outer layers of the peridium apart.

In contrast, the peridium of " Nidularia " have tinted, rigid, spiny, aseptate hyphae that continue into long threads.
35.
The solid or membranous peridium is yellow, often transparent om thin areas, thickened and deeper beneath, surviving as an initially shallow calyculus.
36.
The hypothallus is here part of a morphologic unit with peridium and stem, which serves as a membranous surface of the whole structure with the spores.
37.
The mouth in most species of " earth-stars " is quite prominent, often arising as a small cone at the apex of the inner peridium.
38.
The related genus " Mycocalia " was segregated from " Nidularia " in 1961 based on differences in the microscopic structure of the peridium.
39.
The surface of the peridium is hydrophobic, a feature that helps keep water off the growing hymenium during its development, and gives the fruit body buoyancy.
40.
In most species, the peridioles are dispersed by rain, but they may also be free in the peridium, surrounded by a jelly-like mucilage.
