Calvatia Sporocristata
''Calvatia sporocristata'' is a species of puffball in the family Agaricaceae. Found in Costa Rica, it was described as new to science in 2003 by Spanish mycologist Francisco D. Calonge. Fruit bodies are top-shaped to roughly spherical, measuring by . The outermost tissue layer, the exoperidium, is brown and has a cork-like texture; the endoperidium is thin and paperlike. Inside the puffball, the gleba is initially yellowish-brown before changing to dark brown and woolly as the spores mature. The specific epithet In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ... ''sporocristata'' refers to the crest-forming spines on the spores. Similar '' Calvatia'' species include ''Calvatia lepidophora, C. lepidophara'' and ''Calvatia longicauda, C. longicauda'', but these lookal ...

Puffball
Puffballs are a type of fungus featuring a ball-shaped fruit body that bursts on impact, releasing a cloud of dust-like spores when mature. Puffballs belong to the division Basidiomycota and encompass several genera, including ''Calvatia'', ''Calbovista'' and ''Lycoperdon''. The puffballs were previously treated as a taxonomic group called the Gasteromycetes or Gasteromycetidae, but they are now known to be a polyphyletic assemblage. The distinguishing feature of all puffballs is that they do not have an open cap with spore-bearing gills. Instead, spores are produced internally, in a spheroidal fruit body called a ''gasterothecium'' (gasteroid 'stomach-like' basidiocarp). As the spores mature, they form a mass called a gleba in the centre of the fruitbody that is often of a distinctive color and texture. The basidiocarp remains closed until after the spores have been released from the basidia. Eventually, it develops an aperture, or dries, becomes brittle, and splits, and the spo ...
