Hello,Found by Laurens van der Linde, nov. 2019, The Netherlands, on stems of Alchemilla spec. (family Rosaceae).
In the material I got, I only found 2 perithecia with rather long necks (teleomorph), almost all the black spots I tried where anamorph.
In the end I tried some little black spots ....... luckily the teleomorph (with short necks).
- asci with 8 ascospores
- perithecial necks central
- ascospores lacking appendages
- ascospores 1-septate, submedian
- perithecia about 375 µm
- asci: 28-6-37.6 x 4.3-5.7 µm
- ascospores: 8.6-10.0 x 2.9-2.9 µm
Greeting,
Riet
Hi Riet,
Yes, you're right. Probably G. comari s.l. (cf Monod). You can check in Systematics of genus Gnomoniopsis / Walker & al. (Mycologia, 2010). They established that Gnomoniopsis are generally host specific. Especially several species occur on Rosaceae. But no one on Alchemilla has been sequenced. So ...
Best wishes,
Alain
I'm glad with all this information!
Best wishes,
Riet
