In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores fo ...

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
Mycelium (: mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Its normal form is that of branched, slender, entangled, anastomosing, hyaline threads. Fungal colonies composed of mycelium are fo ...

basidia and may also contain
capillitium threads.
Gleba found on the fruit body of species in the family
Phallaceae is typically gelatinous, often fetid-smelling, and deliquescent (becoming liquid from the absorption of water). It is formed on the exterior face of the cap or the upper part of the fruit body. The foul smell helps to attract insects that help disperse the spores. Chemicals that contribute to the odor include
methylmercaptan and
hydrogen sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is toxic, corrosive, and flammable. Trace amounts in ambient atmosphere have a characteristic foul odor of rotten eggs. Swedish chemist ...

A subgleba is a "sterile, filamentous or chambered tissue which supports the gleba".
