Perithecia on wood of Pseudotsuga menziesii branch

Michael Haldeman, 04-09-2022 01:39

Hello,

I was wondering if anyone had an idea what this is. It was on wood of a small dead branch of a live Pseudotsuga menziesii in a mesic forest in northwestern North America (USA, Washington). The spores are 8/ascus, hyaline, muriform, and 27-29 x 10-12 micrometers.

Thanks so much for any help,

Mike
