Found in a New York City park in a marshy area growing on damp muddy soil. Apothecia about 5mm in diameter. Spores with isolated warts sometimes coalescing and connecting into irregular blobs. Spore size: 17.1 - 20.4µm x 10.3 - 13.2µm (25 spores measured). Q=1.67. Hairs brown. The four longest marginal hairs measured between 1041 - 1265µm x 30 - 44µm. Hair wall averages around 6.8µm wide near the base. Hair roots simple, bi & tri furcate. Wide variation in number of septa, 12 - 22. 3 different keys give me three different answers. Anyone have any ideas?

Re : Scutellinia
Hola Ethan, con estos pelos y estas medidas esporales diría Scutellinia scutellata, presente en todos los continentes, aunque tampoco me hagas mucho caso.
Saludos.

Re : Scutellinia
Hi Ethan
It could be S scutellata but the hair roots don't look complex enough for me. Unfortunately the hairs are a bit long for my next choice which would be S olivascens. I have also run it through my own and other keys and S scutellata seems to be the outcome with most.

Re : Scutellinia
Thanks to both of you. Malcolm, it seems that I am finding many Scutellinias that approach S. scutellata, but are not conclusively that taxon. Do you think sequencing future collections from my area would be helpful, or is there not enough sequenced material to compare?

Re : Scutellinia
Hi
Looking at genbank (other DNA databases are available) and there does seem to be quite a few collections on there. Unfortunately I have not used any DNA testing so don't know how well different species are covered and how acurate the sequences are. If you have ready access to DNA testing I think it would be fascinating to see the outcome.

Re : Scutellinia
Dear Ethan,
B. Jeannerot wrote some time ago on this forum that S. scutellata is a complex of (three?) species. If I recall correctly, he didn't write whether he was able to distinguish them morphologically or if he sequenced any extraeuropean collections as well. Those collections I've seen had a bit longer ridges on spores, but they were just a few, it's probably an uncommon species in our country. Anyway your collection is sure closer to scutellata than to the other species in that group.
