Phallus ravenelii

Scientific name:  Phallus ravenelii Berkeley & Curtis
Derivation of name Ravenelii is named in honor of
Henry William Ravenel (1814-1887) a South Carolina
mycologist and botanist.
Synonyms:  
Common name(s):  Ravenel's stinkhorn.
Phylum:   Basidiomycota
Order:   Phallales
Family:   Phallaceae
Occurrence on wood substrate: Saprobic; solitary or
clustered on wood debris, sawdust, rotten stumps and logs;
August through October.   
Dimensions: Fruit body up to 20 cm tall; head up to 4 cm
wide; stalk up to 3 cm thick. 
Description: Fruit body at first a white to pinkish-lilac egg-
like stage, resembling a puffball. The egg is attached to the
substrate by white to pinkish mycelial strands (rhizomorphs).
The outer wall (peridium) of the egg splits and a hollow,
spongy, whitish stalk expands bearing a head covered with a
slimy, olive-green fetid spore mass.
Edibility: Inedible although Miller states the eggs are edible.
Comments
:  Flies are attracted to the fetid slimy mass and
serve to disperse the spores.
