marginate apothecia
Stefan Blaser, 29-01-2013 12:15
Hello everybody

I do have one more "burden of the past" where I don't get to an identification and hope for your help.


Description: Apothecia dark, hymenial disc almost black, up to about 0.7 mm in diameter. Margin distinct, raised somewhat above hymenium. Margin and Excipulum brown. Hymenium very densely agglutinated, gelatinous. Brown epihymenial matter. Spores are 15-18 x 4-5 µm, brown, smooth(?), two-celled, somewhat thick-walled. Subhymenium brown. Excipulum with mostly globose to ellipsoid or sometimes nearly rectangular cells, mostly hyaline to somewhat brownish. Margin distinct in microscopic composition from Excipulum and Hymenium, very gelatinous, with very indistinct prolonged elements (see photo).


Substrate: Decorticated deciduous wood, most probably Alnus or Corylus


To me it resembles some lichens with its margin, but I recognize no thallus.


Any help is welcome


Stefan

Re : marginate apothecia
Dactylospora? Gib mal IKI zu.

Re : marginate apothecia
Hallo Zotto

Da ist noch ein Schnitt in Melzer (Habe erst ab Donnerstag wieder IKI zur Verfügung). Auf die Gattung Dactylospora bin ich auch mal gestossen, habe aber kaum Literatuir gefunden.

Re : marginate apothecia
Da wäre ich jetzt nicht sicher, ob das Jod überhaupt an den Asci ankam. In Dactylospora sollten die Asci auch in Melzer sehr stark blauen.

Probably D. stygia var. stygia ?
Zotto knows it very well and will be ok after iodine reaction, I suppose.

Re : marginate apothecia
Hello Zotto and Alain

I can detect no evident blueing reaction of the asci. Even if squashed and also not after waiting for some minutes. I can try fresh IKI tomorrow evening, but as you said, Zotto it should also work with Melzer.

What other options are there?

Re : marginate apothecia
Yes, but the yellow iodine should be visible on the photo (plasma staining), otherwise I cannot believe :-)
If yours is rather thin, please try directly in a drop of MLZ.
