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