Hello,I guess the best option how to label this collection is Lachnum rhytismatis s.l., right?
Ascospores measure (4.4) 4.5-5.1-5.5 (5.6) × (1.4) 1.5 -1.6- 1.7 (1.8) µm
Q = (2.64) 2.81 -3.13- 3.47 (3.85)
Asci without croziers.
The apothecia grew on decaying leaves of Acer, in a little brook.
Collected yesterday in Moravia.

Hi Zuzana,
There are in Zotto's L. rhytismatis files, collections on Quercus and Acer leaves without croziers .
And your collection seems also comparable to L. microsporum .
I regularly collect on Acer monspesullanum leaves L. ''aceriphilum'' , with croziers.
Amitiés
Michel

Re : Lachnum rhytismatis s.l., H-, Acer
Hi Michel,
thank you very much for your answer.
I saw Zotto's folders, but it seems (also from older discussions here at ascofrance) that the situation is not fully clear.
I also find the Acer species with croziers now and then, this one is my first H- collection.
Best regards, Zuzana

Re : Lachnum rhytismatis s.l., H-, Acer
My folders say that L. rhytismatis on Quercus is H- and that on Acer both H+ and H- occur, with H- being rhytismatis too. I assume Marketa had sequences of both.
My aceriphilum folder is full of collections, so it seems that true L. rhytismatis is much rarer than aceriphilum.

Re : Lachnum rhytismatis s.l., H-, Acer
Thanks a lot, Zotto. I will ask Markéta - anyway, the collection will be deposited in PRM.
