There was a catch-all “or something” at the end of my speculation as to the cause. :)

Hey, at least I can definitely blame this “bug” on user error! No dissing “my” site; not my fault if users like this so-called “jason” character don’t know how to use it right, heh.

Not with whole chunks of information missing. It did indeed look like you were talking about two or more different things to compare and contrast them, but without any apparent point of reference. I see the original comment has been edited and is now quite legible; thanks.

It was only missing the names of the genera. Couldn’t you guess what I meant? (I slipped into the syntax I use in my private notes, where I use angle-brackets instead of underscores to indicate names. Oops?)

“The key to distinguishing , and is the lobe tips. " and so forth … what? I’m afraid this isn’t very understandable as written. I wouldn’t comment except that it’s so thoroughly garbled as to be impossible to determine your exact meaning, and your English is normally very good. Either you got really sotted on the Memorial Day weekend or something went wrong with the site that mangled the word order or something.

just a guess

The key to distinguishing Physcia, Physcia and Tephromela is the lobe tips. Tephromela has no lobes (purely crustose); Dirinaria has well-defined lobes, but if you pry them off you’ll find there are no little rootlets attaching it below; Physcia also has lobes, but they should be somewhat looser with obvious (generally pale) rootlets. (Pyxine is also similar, but if it has apothecia — as this one does — they would be pure black without a gray rim.)
