Hello everybody!


I collected this Gyromitra in pine forest, Left-bank Ukraine, 21 May, 2011.Could it be G. gigas? 


Spores 31-35*12-14um, with (1)2-3(4) oil drops of different size, with solitary apiculi. 


Grateful before,


Irina

Re : Gyromitra species
Did you test the spore ornamentation in cotton blue? This is important to verify if your collection can be determined as G. gigas, although this is problably the case.

Re : Gyromitra species

Thank you, Nicolas!


I din't do that (but, of course I will do). In the key, which I used it was asked only about spore ends and size of spores. It seemed that I saw spore ends well without staining. Could you advise me some more specialized keys?? What are the distinguishing microscopic features of this species? I will be very grateful for the reply.


Best regards,


Irina

Re : Gyromitra species
About the genus Gyromitra you can take a look to the articles I've been published, with P.-A. Moreau, in Ascomycete.org journal in 2009 :
