Hello,

 

found today and at first glance taken for a small Mollisia, but minutely stipitate (seen only under dissecting microscope). The fresh apothecia have a very faint greyish-violaceous hue, so that Ascocoryne or Ombrophila would be fitting macroscopically, though apothecia are only apr. 1 mm in diameter.

Asci without croziers, deep blue IKI reaction (Calycina-type I suppose)
Paraphyses cylindrical, with one cylindrical vacuolar body appr. 20-30 µm long, medium rfractive, strongly stainied by IKI
Spores fusoid to long-elliptic, hyaline, without septae, oil content 5, appr. 25 x 7 µm
Ectal Excipulum a textura oblita from stipe to cup margin, ending in cylindrical inconspicous protrudings with the same small vacuolar body as the paraphyses.

Scattered on bare dead wood of a Salix caprea stem

Any hints welcome :-)

thank you and best regards,
Andreas

Oh, Ich war sicher ich hätte geantwortet: Allophylaria macrospora.

Hi Andreas,

when I followed my idea Allophylaria and checked Zotto's digital collections I found your's under A. macrospora. Maybe he missed to answer you ;-)

Best regards

Martin

Hallo Zotto, 

vielen Dank!

ist das die Cyathicula macrospora aus deiner alten Schlüsselversion (2006)?
Da war ich auch gelandet, aber irgendwas passte nicht so recht. Schön dass es geklärt ist. 
Ist die Art häufig? Ich hatte sie noch nie bisher ...

LG, Andreas

Du meinst jetzt aber nicht C. megalospora? das ist was anderes. Diese Allophyalria hätte ich nie in Cyathicula gestellt, schon wegen der Paraphyseninhalte.

Ich muss daheim nochmal nachschauen, vielleicht verwechsle ich grad was aus der Erinnerung heraus.
