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 (;

#1338 - Calycina subparilis? -  on hardwood log (;

#1243 - Calycina scolochloae -on Phragmites australis. I almost certain, but I couldn't find any report from North America (;

#1124 - Calycina sp.? - on herbaceous stems (

Thank you,

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.
