Observation 205699: Gyromitra Fr.

Fruiting on a large fallen conifer.

Small stem evident(note in 1st image). Always reminds me of a Gyromitra or Helvella that never fully finished growth.

Elevation: 2700ft.

Temp: mid 70’s.

Hey Debbie-

Totally agree with you that all Gyromitra should have microscopy added in each post. I usually have had some good success in the past with just the macro features and brought this one right along with out a closer(microscopic) look.

Not very useful if it doesn’t prove the species from the jump ;-)

Thanks again,

I get that mushrooms change over time, and that this is one you have collected and successfully IDed before. But to those of us at home, wherever that home is, the photo is not enough to make that ID.

It is always good to test what you think you know. You could well be right. But with the micro, we’d all know for sure, and even learn something, like the range of colors and morphology, right along with you.

Sorry for the sans microscopy Debbie…

I have collected what I still like to call Discina prelata or Discina ancilis in multiple locations, and at multiple different ages here in the PNW for years. All exhibit flat appearing(almost like cup fungi from a distance) and truly do appear red initially.

These were stiff, old and faded(high elevation as well have light color expression to begin with).

Fellow TESC alumni, Dr. mike Beug will no doubt clear things up( or gladly share his opinion) if you contact him via MO.

I will no doubt contribute more microscopy( as I have with most posts for years here at MO) and be clearer with context of images in the future.

Thanks for continuing to strip away the chaff guys!

Thanks again,


even the macro …

doesn’t seem like a good match to ancilis, which Beug describes as reddish brown and undulate/rugulose.

Hard to name a Gyromitra species

Gyromitra species previously assigned to Discina are very difficult to identify only by their morphology. Microscopic characters, especially spores ornamentation on mature ascospores, are required to propose a correct name. So G. perlata (= G. ancilis s. auct.) is an option but it could be also another species (e.g. G. melaleucoides).
