Notes: Getting back to this question, and the clamp connections. Now spent enough time look or not looking for clamp connections, I almost trust myself (almost). But getting back to these, this verifies the id of A. retiruga.
The first micro-shot is of a broken hyphae in Congo red at 1000×. Here you can see the connection between the cells in the hyphae, and there is no clamp connection. Ok, its hard to take a photo of something that is not there, this is just an example of all the connections, after looking around and around for clamps, and there aren’t any here.
The second micro-shot is of a basidia broken away from the connective tissue, with 4 spores still attached, in Congo red at 1000×. I grabbed this shot because it a good shot of the sterigma and spores. It looks like Arrhenia has nice big sterigma for photos.
So, the question was between A. lobata and A. retiruga, and the clear difference between the two was that A. lobata has clamps, and A. retiruga does not. There were some macroscopic difference, but they were variable, so this was an open question. Now the name for this obs. is confirmed.
