... in the vicinity of Wiesbaden-Kohlheck, Germany, Hessen, on a decaying log of Populus tremula, 6.11.2016, leg. Anna Wulfgramm
The specimen (dried) is a little bit premature, I found a lot of unripe asci and only few ripe spores. Those have a form that is fitting better with G. ambigua than with G. infula as it seems to me, but the spores are quite small. This could be due tu the early development stage?
The habit of the ascoma doesn`t seem to be typical for infula/ambigua, but what else should it be ... in autumn?
Who can confirm my suggestion of G. ambigua - or tell a better solution?
Best regards from Lothar
Yes, this is an unusual aspect for G. infula or G. ambigua, but the spore shape agrees with those species... Keep this sample in you herbarium, it could be useful for a future monographic work on the genus Gyromitra.
Hi Nicolas,
surely the specimen will be kept - but if you want, I can send you a part of it or even the whole specimen for fuirther investigations. I don`t necessarily have to keep it myself.
So - don`t you think you can decide between ambigua and infula with the spore shape?
Best regards from Lothar
thanks, Nicolas!
