It’s my opinion…

that anything that looks like a lichen or fungus, or is frequently mistaken for such, has a home on MO. That includes liverworts, algae, even parasitic/saprophytic members of the Ericaceae like Monotropa. Maybe even spraypaint. :)

I wonder if I should keep it on MO

Since it’s not containing anything fungal, technically it doesn’t belong here. But others posted some non-fungal stuff too – including Trentepohlia and other algae (I recently posted it too – see observation 103972). Perhaps there is some value in it being referenced as non-fungal but looking fungal to untrained eye?

I’d go with Nostoc commune, too

Like you said, you should see at least a few isidia and/or apothecia if it were a lichen.

Lichen or Algae?

Can’t figure this one out myself. I don’t see any obvious (to me) lichen structures. The thing consists of what looks somewhat like needle chrystals under the microscope – thick mat of them. I lack experience and tools to furhter disect the thing and figure it out. I think the algae verdict is more likely here (or alien organism?:-)
