Observation 44133: Gyromitra Fr.
When: 2010-04-04
No herbarium specimen
0 Sequences

Numerous specimens emerging from a flower bed on the south-facing side of my home. See Arora’s description of a “gyrose (lobed and wrinkled)” form in Mushrooms Demystified, p. 795. Mistook it during last year’s emergence for a Gyromitra. Stipe smooth, round and centrally hollow, unlike that of Helvella lacunosa (whose cap this wrinkled form resembles).

Perhaps the additional photos from a few minutes ago will be of some help. The stipe is tubular, with a single chamber containing a loose, white, cotton-like pith. The invariably black caps do not remove easily from the stipe, but rather begin to “unfurl” before removal. The largest specimen I’ve seen to date is the one pictured. All are growing directly underneath Bergenia cordifolia (Heartleaf Bergenia) and, like this specimen, can be difficult to remove without breaking.

Unfortunately, Debbie, I do not have a microscope at home yet. Living in a very rural setting (wilderness on one side, national forest on the other), I don’t have local access to one either. I would be happy to dry these specimens and send them out to someone for spore analysis.

Thank you both for your suggestions.

something called Gyromitra longipes in Scandinavia. Even if ascos usually look fine in the microscope (they are fun to watch there), it’s not easy to separate different species by measuring spores:
http://ddr.nal.usda.gov/... (p. 25)

This collection should be dried and saved for a herbarium, because it doesn’t look like any of the proposed names, and it’s hard to beleive that this is the same as a scandinavian one..

do you have a scope at home?

ascos are great fun to look at under the scope, and their IDs become a lot easier: Verpa bohemica has huge spores w/out oil drops; G.esculenta has smaller but still largish spores with twin oil drops.

Also, for simple in hand ID, the cap attachment in the two species vary…the bohemica cap will pop off easily, gyromitra cap is firmly attached.
