Good day


I try to make microphotos for some Discomycetes samples, which looks interesting for me. May be you have some ideas about them.

Re : Discomycete from Spirea branches
Thoug I do not know the species very well, I think this could be Godronia spiraeae

Dear Zotto


Thank you!


According Seaver description spores of Godronia spiraeae are 25-35 x 3-4, but in my sample - up to 70 x 1,1. Therefore, I think it is something another.

Re : Discomycete from Spirea branches
Zotto, do you familiar with the article:
Growes J.W. The genus Godronia // Canadian Journal of Botany, 1965, 43:(10) 1195-1276? I have not access to this article. Possible there are more information about Godronia spiraeae there.

Re : Discomycete from Spirea branches
avec de grandes spores voir peut-être Godronia cassandrae f. spiraeicola (Henn.) Groves

Re : Discomycete from Spirea branches

Thank you, Guy.


I can not to verify your idea , because I have not Groves original article from Canadian Journal of Botany:-( But according Mycobank, basionim of Godronia cassandrae f. spiraeicola (Henn.) Groves is Cenangella spiraeicola Henn. In the original description of Cenangella spiraeicola in Hennings paper spores are even smaller - 10-13 x 1,5-2.


May be you have another information?

Re : Discomycete from Spirea branches
Hi Alex,
this sporesize fits good for the imperfect, Groves gives no indication for the sporesize of this forma so i assume it will be the same as cassandrae only differing in substrate.
i will send photos.
cheers Stip

Re : Discomycete from Spirea branches
Thank you very much for advise and sent Groves article!
My specimens really looking like Godronia cassandrae f. spiraeicola (Henn.) Groves. But there are some confusions because visual similarity of macroconidia and ascospores.

Re : Discomycete from Spirea branches
Yes, that sounds better. But the spore  size of G. cassandrae differs with 40-85 x 1.5-3.5 µm (Groves 1965) from yours in the width. How sure are you with that?

For spiraeae Groves says 20-45 x 2.5-4 µm, which is also much wider than you say.

Re : Discomycete from Spirea branches
In my sample most of asci are immature. I've been doing a lot of preparates in order to see at least one spore. And even those individual spores that I could find were not formed. Perhaps that is why their size does not quite equal to the description of Groves.
I plan to be in the same locations in the Carpathian mountains in 2 weeks and try to find a more mature specimens.
