Psilocistella ?

Hola:

I found these apothecia growing on a sheet of Quercus.
Marginal hairs are grouping as teeth. They are smooth, I do not see any ornamentation or incrustation.
The asci are amyloid and with croziers.
I have reviewed the literature but I can not identify it. I thought perhaps it is Psilocistella quercina.
I would like your help for determination.
Thanks in advance.

Susana

Re : Psilocistella ?
Dear Susana

look here:
http://www.ascofrance.fr/search_forum/25641

This is a very similar one, differeing mainly in the absent croziers. There I compare one with croziers which seems to fit yours, though spores are a bit larger. Could you please supply more measurements? Apothecial size and hair size would be welcome. This seems to be a very rare species, or species complex. Also please keep the material in your herbarium. It may well be that someone would like to sequence it.

I would also be interested in the collection data because I am going to publish this as a new species. the problem is that the genus is still not clear.

Re : Psilocistella ?
Hi Zotto:

Apothecia size is 300-550um
The marginal hairs are up to 130um. The width is 3-3.5um
I have noticed that on the wall of the hairs appear small oileaginous deposits.
I send you the data coleccion.
I have stored the sample for if someone wants to study it.

Thanks, greetings

Susana

Re : Psilocistella ?
Thank you very much!

these drops are difficult to interpret. I suppose they are inconsistently present.

Maybe Teppo Rämä is interested in sequencing, I will tell him about this.

Dear Susana

Teppo is indeed very interested. Now, depending on the abundance you must decide whether to send him the whole or part of the collection. I think 3-5 apothecia are enough. 

Thank you very much!

His address is:

Teppo Rämä

Kvaløyvegen 30
NO-9013 Tromsø
