Torrentispora ? Long necked, partially immersed pyrenomycete
Ethan Crenson, 25-06-2019 21:23
A couple of days ago I found these long-necked, partially immersed pyrenomycetes growing amid a fruiting of Scutellinia erinaceus.  Fruiting bodies are tough and leathery.  The necks do not appear to be sulcate.  Asci are short-stipitate, measuring 82-85 x 8.5-9µm, IKI-.  Spores in water look non-septate, guttulate, smooth, 11-12 x 5µm.  In Cotton blue they look rather thick-walled and 1-septate.  I made a collection similar to this a couple of years ago in the Bronx and there was a very helpful conversation pointing toward Torrentispora, Calyptosphaeria, so I assume that I should look in a similar direction with this collection. But perhaps I do not have enough data here.  I'd be grateful for any help.

Thank you!

Lothar,

Indeed, the Scutellinia in the photos are Scutellinia erinaceus. But I am looking at the black pyrenomycetes that I indicate in the photos with a white arrow.  Do you see the necks emerging from under the damp wood and the partially immersed venter in the first three photos?  It is from those that I obtained the asci and spores in the remaining photos.
