    As anyone found cilia, spinules, or isidia on the rim of apothecia of Melanohalea subolivacea?  I collected it on a coniferous branch along with Melanohalea elegantula on the Helena-Lewis & Clark National Forest in Montana.  I'm attaching photos.  I counted the spores and there are 8 in the ascus.

    I am not sure I have seen exactly those little skinny things, but I see all sorts of lumps and things along the rims. I would think they are not isidia or spinules but just the equivalent of the sort of isidioid lumps one finds all over the thallus on some thalli.

    Very cool looking!

    I saw them on several specimens from different plots.  I think they are actually rhizines.
