Crocicreas culmicola(?) on herbaceous stem

Yatsiuk Iryna

Hello, Friends!


In my old collections (no vital taxonomy, sorry) I've found this tiny asco. It was collected in a steppe region, in spring, on herbaceous owerwintered stem. 


Apothecia bearing scanty "teeth", no hairs observed. 


Asci with crociers, 110-135*11-14 um, euamyloid.


Paraphyses 1,5-2 um wide, swollen at the upper part, up to 4 um , often curved, branched, septate. In IKI paraphyses look like granulate (see photo).


Spores most often 3-septate, 19-24*3,5-4,5 um size. 


Ectal excipulum textura oblita(?) porrecta(?) - see photos


With best wishes,


Irina
