Reticularia lycoperdon

Aethalia sessile, isolated, up to 8 cm long, subglobose to irregular in shape, silvery white to dark brown depending on development, with a smooth, thick, persistent peridium dehiscing irregularly, without columella or true capillitium, occurring on dead decaying wood on the ground.

Pseudocapillitium yellowish, formed by membranaceous, irregular and branched plates connected by fine filaments only 1 to 4 µm in diameter, frayed, with some branches, loosely attached to the peridium.

Spores globose to subglobose, pale yellow under the microscope, 6.5 to 7.5 µm in diameter, reticulate over two-thirds of their surface, with the remainder practically smooth.
