Ascocoryne sarcoides

Scientific name:  Ascocoryne sarcoides
(Jacq.) J. W. Groves & D. E. Wilson
Derivation of name:  Sarc- means "flesh" or "fleshy" and
-oides means "resembling."
Synonyms:  
Common name(s):  Purple jelly drops.
Phylum:   Ascomycota
Order:   Helotiales
Family:   Helotiaceae
Occurrence on wood substrate:  Saprobic; on deciduous
stumps and fallen logs; September through October.  
Dimensions:  Individual cups 0.5-1 cm wide, forming
larger masses when coalesced.  
Description: Purple lobes initally emerge out of wood,
swell into cup or disc-shaped ascocarps which typically
coalesce to form a violet to purple to reddish-purple
gelatinous, irregular mass.
Edibility: Unknown.
Comments:  Ascocoryne cylichnium is very similar in
appearence to A. sarcoides and the two species can
only be differentiated with certainty by the spores. Based
on spore measurements, the fungus in Figures 1 to 4 is
A. sarcoides. When occurring as irregular masses, both
species resemble basidiomycete jelly fungi. Unlike the
jelly fungi, Ascocoryne species produce ascospores, not
basidiospores.

Figure 4. The individual ascocarps of Ascocoryne
sarcoides
are disc or saucer-shaped. It's only when the
fruit bodies grow close together in larger masses that they
assume an irregular jelly fungus-like shape. Because of this
variation, Ascocoryne sarcoides will key out using either
the "cup and saucer" key or the "jelly" key in the initial
shape key used at this website. Photo © John Dawson.

the bark. As they grow and coalesce, clusters of ascocarps
come to resemble irregular, gelatinous masses such as the
