Morganella subincarnata

Scientific name:  Morganella subincarnata (Peck) Kreisel
& Dring
Derivation of name: Sub- means "somewhat" or "almost"
and incarnat- means "flesh-colored." Subincarnata, then,
means "somewhat flesh-colored."  
Synonyms:  Lycoperdon subincarnata Peck
Common name(s):  Ruddy puffball.
Phylum:   Basidiomycota
Order:   Agaricales
Family:   Lycoperdaceae
Occurrence on wood substrate: Saprobic; scattered or in
groups or clusters on decaying (often moss-covered)
deciduous logs and stumps; August through October.   
Dimensions: Fruit body 1-3 cm wide.    
Description: This puffball is nearly globose to pear-shaped
and attached to the substrate by white mycelial strands
(rhizomorphs). The pale pinkish-brown spore case (peridium)
is covered with purplish-brown to reddish-brown spines and
warts. An irregularly-shaped apical pore develops at maturity.
The internal spore producing tissue (gleba) is white and moist
at first and becomes purplish-brown and powdery at maturity.
Edibility: Unknown.
Comments: Compare with Lycoperdon pyriforme which
differs in coloration of the spore case and mature spore mass.
