Both are reported by CNALH for Illinois. Records are from Field Museum of Natural History. Doesn’t give collectors or date, just rough lat/long (which might be centroid for the state and thus bogus). Bruce Ryan agrees with you however, and doesn’t include either species.

Ryan does mention subelliptica as a “northern species”. Oh, and P. neglecta = P. pseudobufonia. Back down to 3 or 4 species, with subelliptica rare at best. Ozarks species are probably considered “southern”, so just ignore.

P. laevigata – silvery white to greenish white, very thin, widespread
P. macounii – olivaceous, perithecia quite crowded, on hardwood bark in Great Lakes area
P. pseudobufonia – grayish olive to pale green, thick and “waxy”, UV+y, widespread in east

So, assuming it really is Pyrenula you’ve finally convinced me it must be P. pseudobufonia. Very easy to verify among these three species: it is UV+ bright yellow, even in relatively long-wavelength “over-the-counter” UV.

Banished species :-)

P.hallii and P.prospersilla don’t have any online presence at all – that’s strange.

Expand the search a bit and you find a couple more in the area

Pyrenula hallii
Pyrenula laevigata
Pyrenula macounii
Pyrenula prospersilla
Pyrenula pseudobufonia

Ozarks have several more. Southern Ontario has P. macounii and P. subelliptica as well as your two. Straights Counties of Michigan also claims P. neglecta.

I think you get the idea! :)

No specimen, sorry.

There are two species found in WI (so far) – P.laevigata and P.pseudobufonia. The former seems like it has light-colored thallus, and is rare in WI, but I couldn’t find any good description of it. The latter seems to fit the bill, visually anyway, and supposed to be pretty common.

Gotta be Pyrenula

Will I get to play with a specimen of this later? :)
