Observation 11220: Peziza Dill. ex Fr.

When: 2008-09-15

Collection location: Forest near Elgin St., Pembroke, Ontario, Canada [Click for map]

Who: Paul Derbyshire (Twizzler)

No specimen available

This delicate little cup fungus was almost overlooked, growing near one end of a fallen branch that also sprouted the mushroom of obs. 11219.

It looked brownish to my eye; imagine my surprise to find that it’s actually a lovely, delicate pink in the bright white light of the camera flash. Some photos show this cup as it appeared to my eye, and some as it appears in bright white light.

Size of my fingertip.

The general area contained about six species of agaric; besides obs. 11219, obs. 11221, 11222, 11226, 11227, and 11228 were all from the same small area.

The fifth photo shows the cup three days later. It has doubled in size and the pink tones are more muted and “dusty”, but more visible to the eye in natural light, too. The sixth photo is after an additional three days. It’s larger again, but only slightly. The seventh is after four more.

Recognized by sight: The opening in the side suggests Otidea.
2% (3)
Used references: Web search. Only species I found described as sometimes being pink.
15% (3)
Recognized by sight: Otidea has a smooth exterior surface. This looks like Helvella or Peziza.
44% (2)
Recognized by sight: Looks more like a Peziza to me than either an Otidea or a Helvella. However, it is most likely to be one of the myriad other genera of small cups. But as Debbie points out you’d need a scope to get any further.

Helvella or Otidea

Had it been much more brown, I would have suggested Helvella acetabula. But there is no obvious veining under the cap. The older specimen looks like a mis-shapen Otidea, so I guess I’d have to go with that as a preferred name.

Otidea onoticia are also known as “donkey ears”, and look like them.

To get a species for this pretty little cup, you’ll need a scope, and the literature to back it up!
