I found this tiny pyrenomycete in Brooklyn. Tiny black roughened ascomata, less than .5mm, superficial on bare wood (probably Quercus). Red around apical opening. 1, 2 & 3-septate hyaline spores measuring 16-20µm by 5-5.5µm.
Any help would be greatly appreciated.
Thanks!

Re : Byssosphaeria ?
Hi Ethan,
your fungus seems to fit well Byssosphaeria rhodomphala. Are you on the tropical side of Brooklyn?
Cheers,
Jacques

Re : Byssosphaeria ?
Hi Jacques, I was just looking at Ethan's photos and notes on this and following your lead. It really does seem to be Byssosphaeria rhodomphala! We looked at a paper Algunas especies del género Byssosphaeria (Melanommataceae, Pleosporales) de Veracruz, México by Santiago Chacón-Zapata y Fidel Tapia-Padilla. Revista Mexicana de Biodiversidad 84: 739-745, 2013. The taxon is given from Mexico and Ohio in the United States. We feel like this is a good determination given that information, but we wondered if you have much experience with the genus and might offer additional input?
Thank you!
Thank you!
