A Gyromitra from Iran
Reza Shaian, 18-10-2011 07:41
This Gyromitra collected last week from Iranian North forests under Carpinus betulus and Fagus orientalis. Spores are ellipsoid 18-22 x 6-8 with 2 dropletes, without apiculus. Its like G. infula, whats your opinion?

Re : A Gyromitra from Iran
Cher Collègue,

Cette espèce a le faciès de Giromitra infula et de G. ambigua. Cependant ces deux espèces présentent, à maturité, des appendices polaires de forme arrondie et les ascospores sont plus grandes, surtout chez G. ambugua. La question est, les ascospores observées et mesurées étaient-elles matures ?? Si oui il pourrait s'agir d'une espèce particulière, et il faudrait creuser. Si non, je vous invite à retourner à cet endroit pour effectuer une nouvelle récolte afin d'observer et de mesurer des ascospores matures !


Cordialement


René

Re : A Gyromitra from Iran
René is right, but your specimens look like G. infulata (on my own collections, spores measure 20-23.5 µm in length). G. ambigua has larger spores with apiculi more evident; it's also a boreo-arctic species.
You can freely download the first issue of Ascomycete.org dedicated to the genus Gyromitra, subgenus Gyromitra, to get more information, here: http://www.ascomycete.org/en-us/journal/volume1.aspx

Re : A Gyromitra from Iran
Thanks Nico and Rene. Yes, I have paper and also, I think it is G. infula. This is the first from G. infula/ G. ambigua in Iran.
