Growing on fallen twig of Picea sitchensis

Post by Chris Johnson » Sat Mar 14, 2020 11:20 am

Apothecia dry and incurled when found; hydrated as images – possibly erumpent. Inamyloid in Melzer’s.
Spores 5.6-8.6 x 2.1-2.6 µm, smooth with two guttules.
Asci 35-41 x 5-5 µm
Paraphyses filiform with some branching.
I’ve failed to key this out and would welcome any suggestions.

An update: Brian Douglas suggests it could be Ionomidotis fulvotingens. This was the closest I got but was discouraged by the texts suggesting a broadleaf species. He goes on to say: "... I'd recommend vouchering it and keeping it safe, and keeping an eye out for more, in case anyone is doing a DNA based revision of this group in the near future. I suspect the different host might indicate it's a distinct and undescribed species."
There is very little of it and it may be safer at Kew. I'll as Paul Cannon if he would like it.
