The gleba is a solid mass of spores, generated within an enclosed area within the sporocarp. The continuous maturity of the sporogenous cells leave the spores behind as a powdery mass that can be easily blown away. The gleba may be sticky or it may be enclosed in a case (peridiole).
It is a tissue usually found in an angiocarpous fruit-body, especially gasteromycetes. Angiocarpous fruit-bodies usually consist of fruit enclosed within a covering that does not form a part of itself; such as the filbert covered by its husk, or the acorn seated in its cupule. The presence of gleba can be found in earthballs and puffballs. The gleba consists of mycelium, and basidia and may also contain capillitium threads.

- "gleba definition". Mycological Glossary. Illinois, United States: Illinois Mycological Association. Retrieved 2008-10-24. "As the spores mature, the sporogenous cells often liquify and/or disintegrate, leaving just the spores behind as a powdery mass that can easily blow away... In other cases, the gleba may be sticky, as in Sphaerobolus stellatus; or it may be enclosed in a case (called a peridiole), as in the Nidulariaceae."[dead link]
