Hymeonoscyphus?
Malcolm Greaves, 03-07-2014 21:51
Malcolm  GreavesHi
Can anyone suggest what this might be.
Small 2mm yellow capped Hymenoscyphus? species. The stalk is pale/white with hairs especially towards the base.
The ascii tips are blued in Lugol and the non-septate spores are averagely 20 x 6. They are asymetrical and look like a section through an aircraft wing.
It was growing on a twig in alder/willow wet woodland.
Thanks
Malcolm

Re : Hymeonoscyphus?
This spore shape is a weak variant of the common scutuloid spores of Hymenoscyphus s.str.

From spore size and ecology it could be H. calyculus. Necessarly would be to clarify whether the asci arise from croziers. But even then the H. calyculus complex is difficult.
