2 Gyromitra species

Hello, Forum!


I have 2 findings of Gyromitra, collected on 2 May, 2011. As I'm a beginner in operculate discomycetes, I ask for your verification and guidance. 


The first sample is probably G. esculenta. It was collected in a mixed oak-pine forest on the sand soil. It has spores with 2 oil drops, 18-25*10-11 um. The first and the second photos correspond to this species.


Irina

The other species was collected in young oak forest. To my mind it is close to Gyromitra fastigiata, but it has relatively smaller size of spores (18,5*25-9*11,5um). Spores contain several oil drops (many small drops and/or 2-3 large drops).


The next photo corresponds to this species.

Re : 2 Gyromitra species
Hi Irina,

macroscopically, they indeed look like G. esculenta and G. fastigiata. I think the fruit body of the latter species is not fully mature and therefore the spores are too small. Fully mature ascospores of G. fastigiata also posses small finger-like apiculi and a reticulate ornamentation.

Best wishes,

Gernot
