Ciboria?
Hans Adema, 07-04-2016 16:10
A friend of mine found these Cup Fungi on barren soil in a parc in Amsterdam. No Dumontinia, the spores are those of a Ciboria I think. They grow on a soft black sclerotium wich is pure white inside. Can anyone help me?

Re : Ciboria?
Is the fungus of a similar size as D. tuberosa?
I need to see the spores in water, then it is possible (not easy) to discern if there are two or four nuclei in each spore. D. tuberosa is 4-nucleate.

Did you notice any plants around?

Re : Ciboria?
They are smaller than Dumontinia. Plants in the surroudings were Corydalis, Cheledonium, Betula, Adoxa and Lysimachia nummularia. There is a Ciboria on seeds of Betula, but i do not know if that species has such a big sclerotium.

Re : Ciboria?
When there is Corydalis then I suppose this is the host plant. The apo diameter is probably around 5 mm, or?

On Corydalis and Ficaria occurs an apparently undescribed species which is very easily confused with D. tuberosa.

Re : Ciboria?

This is no Ciboria - Ciboria species do not have sclerotia but only sclerotize the substratum that may become black for instance. Ciboria betulae is a very small species with warted spores and has nothing to do with your specimen.


Regards from Lothar


P.S. the plants around. No Anemone nemorosa - o.k.


What about Ranunculus ficaria, Polygonatum, Paris?

Re : Ciboria?
Or Corydalis :-)
Hans Adema, 08-04-2016 14:29
Re : Ciboria?
Paris and Polygatum don't occur in the surroundings of Amsterdam, so Corydalis en Ficaria are left as possible host
