Acanthostigma multiseptatum ?

Hello,
In the Bronx, New York City last Saturday I found these setose superficial pyrenomycetes on a branch of hardwood. I think they are Acanthostigma multiseptatum, mostly based on spore features. I used the paper by Andy Miller and Itthayakorn Promputtha (2010) to reach this tentative ID.
The hairs are brown measuring 86-112 x 5µm. Asci bitunicate and IKI-, 111-116 x 17-24µm. Spores multiseptate measuring 84-89 x 7.5-9.9µm. I counted up to 14 septa, the spore slightly constricted at some of the septa.
The description in the Miller/Promputtha paper says the spores should not be constricted at the septa, but the length/width seem to fit and other features seem mostly within range. Am I correct that this is A. multiseptatum, or am I mistaken?
Thanks in advance.
Ethan

Thanks Andy! By the way, if you don't mind I'd like to contact you by email about a (sort of) related matter.

Sure thing. amiller7@illinois.edu
If you have sufficient material, we should try to sequence this collection... or maybe even culture it.
Cheers,
Andy
