Species Lists


That apothecium is from L. columbiana growing adjacent to the host L. vulpina/lupina. I’ll add a photo of the twig.
Phacopsis is on L. lupina/vulpina at right, which was intergrown with some L. columbian, and was quite distinct when I removed it from the twig.

Thanks Jason for your comments on Letharia species on the other observation.

This had both ascospores and conidiospores. I’ll try to get back to you on this tomorrow.

Aha! I was wondering…

…why you were posting L. columbianum. :) I’ve seen this before, I’m sure. I had no idea I was looking at a parasite. Does it have spores or conidia? Are there any other look-alikes? Thanks for posting this.
