Observation 205667: Strobiloscypha keliae N.S.Weber & Denison

Growing on redwood cones and twigs. The same thing as Observation 1993013, which was a single specimen, found on the same spot a week earlier.

Flesh firm. Distinct hairs in only one specimen.

Spores J-, 18-24 × 10-13. Asci ~300 × 17. Paraphyses septate, 3 microns wide, 5 microns at tips.

Thanks to Nicolas Vanvooren for suggesting the name Strobiloscypha (for Observation 199013).

Hi Sava.
Today I revised a similar collection by B. Chapman (http://mushroomobserver.org/176022) and my conclusion is that the species is Strobilosphya cupressina. Of course, I compare my microscopic data with those given for S. keliae (by Weber & Denison, 1995) and the differences are significant: spore size and ornamentation, hairs present on the studied collection. In the other hand, your own sample possesses hairy apothecia, so this character has problably been overlooked in the original collection. Did you check the presence of warts on ascospores? After Weber & Denison, this character can be seen in Cotton Blue at 1000×.
