A Bird’s Nest Montage A collection of four photos showing the maturation of the fruiting body of Nidula niveotomentosa. The upper left photo shows the fruiting body with the epiphragm (lid) inact. The photo on the top right shows that the epiphragm has ruptured exposing the jelly like material within while the photo on the lower left shows the exposed peridium (nest). Finally, the photo on the lower right is a closeup of the peridioles (eggs) which contain the spores. Canada,Geotagged,Nidula niveotomentosa
