Added new tree

with additional Gyromitra sp from IN that looks close to G. korfii.

I’ve added a tree using sequences from the 3 most recent

molecular studies with the addition of the subject sequence, the Oregon G. montana sequence and the G. korfii sequence from Indiana. It looks like G. montana is more closely related to the Eurasian taxon G. gigas than it is to G. korfii from eastern North America. And G. korfii looks to be synonymous with G. ticiniana with the name G. korfii having priority I think. And it looks like the G. montana material from Oregon and Arizona are the same.

G. korfii ITS sequence

Steven Russel has kindly donated an ITS sequence of Gyromitra korfii. It is indeed quite a bit different than both G. montana and G. gigas.

This is the sequenced collection: https://www.inaturalist.org/observations/24704538

Right, sure would be nice to have ITS on G. korfii

That may be definitive. Pretty surprising that it hasn’t been done by now by someone for the most recent molecular studies or one of the eastern clubs. I’ll check around.

If G. montana and G. korfii have the same LSU

Then we definitely need to get ITS from G. korfii. Also TEF1 from both G. montana and G. korfii.

G. korfii season is over, not sure who saves those things.

LSU is coming.

This may be the same as Jonathan’s material from Oregon. Neither are G. gigas. Hopefully LSU will tell us more though Methven et al. 2013 looked only at LSU and concluded that G. montana=G. korfii.

Interesting sequence!

I think this matches Jonathan’s sequence in Genbank, except that his sequence has some noise in it.

Too bad all of the sequences for G. korfii in Genbank are LSU – if you could have them run LSU on this too we could see for sure that this is different from G. korfii. Based on habitat and how the two species look, I am pretty sure the sequences would differ by a significant amount.

This definitely shows that G. montana and G. gigas are not synonymous.

I initially proposed G. montana for this obs but MO listed it as deprecated

with G. korfii as the preferred name. From discussions on other postings it seems that G. montana may be the name for western specimens and G. korfii for eastern specimens (G. gigas for Euoropean) but I can find no study to support that assertion. Anyone have any information to help clarify this?
