Scutellinia erinaceus

Scientific name:  Scutellinia erinaceus (Schwein.) Kuntze
Derivation of name:  Erinace- pertains to a hedgehog.
Synonyms:  Patella erinaceus (Schwein.) Morgan;
Peziza erinaceus Schwein
Common name(s):  Orange eyelash cup
Phylum:  Ascomycota
Order:   Pezizales
Family:   Pyronemataceae
Occurrence on wood substrate: Saprobic; clustered on
decaying wood of deciduous trees; July through October. 
Dimensions: Fruit bodies are 1.5-3 (4) mm in diameter.   
Sterile outer surface:  Dull brownish-orange with a fringe
of long brown hairs around the perimeter of the cup. These
marginal hairs are less than 1 mm long.       
Fertile inner surface: Yellowish to pale orange-yellow
when young to dull orange at maturity.
Edibility: Inedible.
Comments:  According to Denison, the combination of small
size, gregarious habit and yellowish pigmentation make this the
easiest member of the genus to identify in the field. Even so,
confusion with related species is possible. Scutellinia
erinaceus
may be difficult to distinguish from small specimens
of Scutellinia scutellata although S. scutellata usually has
a deeper red color. Scutellinia setosa, a species similar in
size to S. erinaceus, is orange-red rather than orange with
yellow overtones. All these related species differ in
microscopic traits and study with a microscope may be
necessary to confirm species identification with certain
specimens.
