Lycoperdon perlatum

Scientific name:  Lycoperdon perlatum Pers.
Derivation of name:  Perlat- means "widespread" perhaps in
reference to the broad distribution of this species in North
America.
Synonyms:  Lycoperdon gemmatum Batsch
Common name(s):  Gem-studded puffball; Devil's snuffbox.
Phylum:   Basidiomycota
Order:   Agaricales
Family:   Lycoperdaceae
Occurrence on wood substrate: Saprobic; solitary to
scattered or clustered on the ground or sometimes on well-
decayed wood or mulch; July through October.  
Dimensions:  Fruit bodies are 2.5-6.5 cm wide and 2.5-8 cm
tall.   
Description: This puffball species is round to pear or turban-
shaped usually with an elongate, stalk-like base. When young it
is white and covered with conical white spines with shorter
spines and granules between them. With maturity the longer
conical spines are usually broken off leaving a pattern of pits or
net-like scars on an aging yellow-brown surface. The spore-
producing internal tissue (gleba) is moist and white at first,
turning olive-brown and powdery when mature. A pore-like
mouth forms (the ostiole) at the apex at maturity allowing
spores to be "puffed out" when the outer case is disturbed by
raindrops or twigs striking it.
Edibility: Edible.
Comments:
This species is edible only when the internal spore
tissue (gleba) is completely white and uniform in appearance.
Care must be taken not to confuse puffballs with young stages
of Amanita species which are enclosed by a universal veil.
A longitudinal section of a young Amanita will reveal some
tissue differentiation into gills. Gills never occur in puffballs.
