Apothecia very, very young 0,4 mm-0,5 mm above wood indeterminate (probably quercus) worked as part of a fence.
The micro is perfect with the plates DVD Baral HB_3562, HB_3864-1, HB_3864-2 and HB_7014_7015
I guess that it is correct.
Best regards

Re : Diplocarpa bloxamii
Also reminds me of Trichopezizella cf subsulphurea .
The hairs appear to be too differentiated for the Diplocarpa.
cheers

Re : Diplocarpa bloxamii
The microscopy is clearly Diplocarpa bloxamii, but the macro not.
This species is presently under work by Kadri Pärtel and me. How abundant is your sample? Important would be a median section to see the excipulum, and a KOH test whether red.brown pigment extrudes upon contact with KOH.
Although Kadri gained a sequence of this species, it might be that she is interested for a further analysis.
Where did the conidia come from?
Great record! I am interested in the collection data. Also please have a closer look at the broken wood, is it obviously ring-pored (typical of Quercus)? A macrophoto of the cross-broken wood would be helpful.

Re : Diplocarpa bloxamii
I found this species (teleomorph + anamorph) also in the Netherlands in 2013: 1st record for the country. Please let me know if you are interested in further details.

Re : Diplocarpa bloxamii
Oh yes, if you have photos etc. please send to me. Also the collection data. The anamorph was never reported in the literature, at least I never found a matching description.

Re : Diplocarpa bloxamii
Hallo
Im Prinzip ja, ich denke die Art ist weit verbreitet, aber doch selten auftretend und nur durch Zufall zu finden.

Re : Diplocarpa bloxamii
Hi
I would like to see if it is possible to photographs of the species, at different stages of growth, both the telemorfo and the anamorph.
Thank you all.

Re : Diplocarpa bloxamii
Hi
Sending pictures with KOH, I believe that the apothecia are very young and therefore very little developed to give the right response.Only there is a dissolution of the yellow pigment of the hair.
Best regards

Re : Diplocarpa bloxamii
Yes, I think aölso that the apotehcia are unsually little developed. The extruding yellow sap is typical indeed. maybe it would be more brownish in higher concentration.
Did you test the separate anamorph heaps for conidia and conidiophores?

Re : Diplocarpa bloxamii
The species was found on 10/10/2013 in the Raaphof (Bunnik, near Utrecht), 52.03N 05.13 E. It is a small deciduous forest on river clay, mainly Fraxinus, Quercus and Populus.
The substrate was a rotten piece of unidentified wood, the ascocarps were hidden in a crack, but the yellow anamorph accompanying it was striking (the reason for collection).
The hymenium was olive green with beige margin, outside dark brown, hairy.
Largest ascocarp 3 mm in diameter, spores 6-8,5 - 3-4 micron, apices of paraphyses fusiform and septate. Conidia in chains, about 5 x 4 micron.
I made only some microscope photos of paraphyses and spores.

Do you know the paper of Ribollet (UN ASCOMYCETE A RECHERCHER: DIPLOCARPA BLOXAMII (Berk. Ex Phill.)Seaver, Cahiers Mycologiques Nantais N° 14 - juin 2002)? The paper describes both teleomorph and accompanying anamorph.

Re : Diplocarpa bloxamii
Thank you very much for drawing my attention to this paper which I did not know. Actually these stalked stilboid conidionata closely resemble those I have drawn in 1988 and 89. It seems incredible that this anamorph might be undescribed and unknown.

Re : Diplocarpa bloxamii
Hi
Thank you Eduard for the information, did not know, I have searched internet and already have consulted it.
At the moment I seen the telemorphos, we will continue looking to see if we are with the anamorph.

Re : Diplocarpa bloxamii
Hi
In this new collection the apothecia are already growing, and there are enough anamorphs? or at least that stage initial conidiana.
Best regards.

Yes, this is obviously the anamorph I also saw. But yours are sessile, are they?

Re : Diplocarpa bloxamii
Hi
I would not say foot, is a "central column" that leave the conidiophoros, this very well described in the lamina HB 3864 but with hair up to the substrate.
Removed very easily from the substrate.
Best regards.
