Microglossum rufum

Scientific nameMicroglossum rufum (Schwein.)
Underw.
Derivation of nameRuf- means "rufous" or "reddish" which is
odd considering this fungus is typically yellowish to orangish.  
SynonymsGeoglossum rufum Schwein. 
Common name(s):  Orange earth tongue; Yellow earth tongue.
Phylum:   Ascomycota
Order:   Geoglossales
Family:   Geoglossaceae
Occurrence on wood substrate:  Saprobic; scattered to
clustered in moss, rotten logs, and humus; July through
September. 
Dimensions:  Up to 6 cm tall.   
Description: These orange to yellow fungi consist of a
roughened stalk and a distinctly compressed, longitudinally
furrowed, or spoon-shaped head.

Comments: This species is sometimes confused with
Cordyceps militaris. C. militaris, however, has dark
orange bumps (i.e., perithecia necks) embedded in the
orangish head and if dug up carefully, will be found
attached to the larva of a butterfly or moth.
