Calycina?
Khomenko Igor, 02-12-2021 18:30
Khomenko IgorHi, this fall around Ottawa, ON, Canada I found a few Calycina species that I couldn't identify or uncertain with id. If someone is familiar with these species and could help, I will be very appreciative.

#1348 - Calycina alni-viridis? - on Populus twig (https://inaturalist.org/observations/101297805);

#1338 - Calycina subparilis? -  on hardwood log (https://inaturalist.org/observations/101035601);

#1243 - Calycina scolochloae -on Phragmites australis. I almost certain, but I couldn't find any report from North America (https://inaturalist.org/observations/97930955);


#1124 - Calycina sp.? - on herbaceous stems (https://inaturalist.org/observations/93768577).


Thank you,
Igor

Re : Calycina?
Hi Igor

The first could well be alni-viridis, also the second seems to be C. subparilis, yes, the third is Calycina scolochloae, the fourth sounds very interstung, no idea.

For better comparison I would be happy if you send me the images by mail. I see no batch download option, and single is time-consuming.

Re : Calycina?
Now I am processing your finds.

C. alni-viridis seems correct, not very yellow but otherwise o.k. The LBs in the spores appear to vary in size.

C. scolochloae: I see the spores are shorter than what I see. E.g. the sample from Spain (17.I.2016) had spores 12,5-18,5 x 3,5-4,5.

The others later.

Re : Calycina?
C. parilis fits very well I think.

But the Calycina sp. I do not know and cannot name.

Re : Calycina?
Thank you, Zotto

Calycina alni-viridis specimen was found covered by fallen leaves and we had freezing temperatures during the nights, so it could explain the lack of bright yellow color.


Did you mean C. parilis or C. subparilis? My specimen is lacking croziers and I see you saved it to C. subparilis folder.


Regards,
Igor

Re : Calycina?
Yes, the yellow is variable on each disk, quite strange. But the paraphysis vacuoles are nicely yellow.

Of course I meant subparilis, sorry.
