Talk about being put on the spot!

It’s hard to tell from photos, but when I see this sort of thing the wrinkles are usually somewhat hollow and fragile. If so, that would make these pustulose. I think I see some soredia. The question is whether the pustules rupture and break down into flakes (dactyls) or powdery/granular fragments (soredia). I’ve seen the latter called pustulose-sorediate. An example of this is Aspicilia simoënsis (on rock in west, therefore works for neither of your observations!)

As for areoles… I’m not so much seeing cracks separating this into separate units. I suppose the opposite of areolate should be “continuous” but that doesn’t really conjure up the right image for me, so I’ll just skip that dimension altogether! :) Instead how about let’s just call it verrucose or rugose?

I’ll put my gloves on…

And wait for him to swing first!

I ask because I saw a somewhat similar crustose like lichen (at least in form) on live oak bark yesterday that had no apothecia, no obvious soralia or isidia, it was just sort of lumpy and bumpy, contiguous, not aereolate or verrucose, and I didn’t even know how to describe it at a basic level.

I am just an amateur suddenly caught in the middle of the adult game :-)

Whether it’s areolate, squamulose, chinky areolate, verrucose or any other of those funky terms – you have to duke it out with Jason :)))

What’s going on?

With this lichen I mean, not those lazy admins…
So how do you describe the form of this lichen, it’s not aereolate, not squamulose is it?

Blame it on those lazy, good-for-nothing admins…

I’ve been struggling with uploads to MO for a long time; today is just obscene.

Was this a mistake?

I think MO may have been having troubles with traffic and failed uploads recently… but I’m afraid I just deleted a whole stack of error reports without even opening them… :(
