Enrique RubioHi again
These minute (200-300 microns) erumpent, gregarious, globulose blackish ascomata are covered by an ephemerous greenish blue tomentum and they vertically collapsing when dry.The fungus was collected on decorticated wood of Prunus dulcis in central west Spain, a region with a mediterraneous climate.
The asci have not a conspicuous apical apparatus and the ascospores are cylindrical, straight to allantoid, smooth, hyaline or sligthly yellowish.I think it could belong to the genus Nitschkia.
Have you some idea for this collection?

Re : Nitschkiaceae
This is the same species that was sent to me by Javier Bometon.  He can share his photos if he likes.  I sequenced this for ITS-LSU.  Sequences for this species are not in GenBank as nothing came close.  The closest match was Cryptosphaeria.  This is not a Coronophorales.  If someone would like to identify the species, I would be happy to send them the sequences.  I might even send you a shiny US Dollar coin for a correct name... ;o)

Cheers,
Andy

Re : Nitschkiaceae
Hi Andy
It is strange for a member of Diatrypaceae that the ascomata are not immersed and that they collapse easily.
I, too, join you in your offer.
Thanks!

Re : Nitschkiaceae
It is very strange, but other things outside of the Coronophorales are known to collapse easily such as Thaxteriella pezizula:  http://www.discoverlife.org/mp/20q?guide=Tubeufiaceae

Someone could win US$2.00 - ha!

Re : Nitschkiaceae
Does anyone know if this fungus, which is extremely common on Prunus dulcis bark, has been formally described?
