Guepiniopsis buccina

Scientific nameGuepiniopsis buccina (Pers.) L.L. Kenn.
Derivation of nameBuccin means a "trumpet," perhaps in
reference to its trumpet-like shape.
SynonymsPeziza buccina Pers.  
Common name(s):  
Phylum:   Basidiomycota
Order:   Dacrymycetales
Family:   Dacrymycetaceae
Occurrence on wood substrate: Saprobic; scattered to
grouped on dead branches of deciduous trees; summer.  
Dimensions: Stalked, up to 1 cm tall with apical portion
about as wide, cup-shaped to cone-shaped.   
Sterile outer surface: Yellow or orange, ribbed.         
Fertile inner surface: Yellow or orange.
Edibility: Unknown. 
Comments: While resembling ascomycete cup fungi, this
tough, gelatinous fungus bears tuning-fork basidia, making
it a basidiomycete. This specimen was found near Hickory
Run State Park, PA. Ellis and Ellis describe G. buccina as
the only one of three species in the genus that grows on
deciduous wood. Apparently not common in the Northeast,
it is the only Guepiniopsis species recorded during NEMF
forays and it was only found two times (Kerhonkson, NY
and Rindge, NH).
