I recently found a very typical "Amicodisca habitat" with slightly dried out water ponds with wet small/medium sized deciduous wood debris. Amicodisca virella was plentiful, but there was also one population of Amicodisca svrcekii. A. svrcekii with clearly less than 15 um long spores with small bipolar vacuoles, so no doubt there.
I am not that familiar with svrcekii so my question is that are the apos really this different in size? The big one is svrcekii and the small ones virella. On the same piece of wood in this case actually.

Re : two Amicodisca
I measured in A svrcekii 0.2-0.35 mm on ?Sambucus and 1 mm on Qurecus, and in A. virella 0.2-0.55(-0.7) mm in two samples on Salix. So I think apo size is variable and not correlated.
From A. svrcekii on Quercus (HB 7022) I have an ITS sequence, while Stip has ITS and LSU from A. virella.They cluster in a clade with rather high distance. So it would be great if we could compare these data with yours if you succeed with this.
Strains of Amicodisca sp. in genBank appear to belong to a Dematioscypha.

Re : two Amicodisca
all right. I kind of thought that they would still overlap sometimes, good to know that it has been recorded. Svrcekii shot spores well and virella too, so we should have material to compare to fairly soon. Also Stip send us A.virella previously and it was exctracted succesfully.

Re : two Amicodisca
I have a recent collection of A. svrcekii from Massachusetts, USA and one of A. virella from New Brunswick, Canada. If someone is working on these and wants North American material you are welcome to them.

Hello Jason,
I appreciate your offer! We (Karen Hansen, Seppo Huhtinen and I) are working on the systematics of "Hyaloscyphaceae". For now, our main focus is the "Hyaloscyphaceae sensu stricto". Arachnopezizas are getting some attention as well. American material is more than wellcome, it's all Eurasian so far - what a bias! I'll write you in lenght once back in the office.

Re : two Amicodisca
Excellent. I also have a few species of Arachnopeziza, Proliferodiscus and others if you would like to use them as well.
