I would say this is likely to be S olivascens possibly a smaller spores variety given the name var minutospora by B Jannerot

Malcolm, thank you!  Is there anything that you can see that would exclude S. crinita?  I just used the key in Schumacher, T. 1990. The genus Scutellinia (Pyronemataceae). Opera Botanica. 101:1-107.  I landed on S. crinita.  As something that Seaver knew from North America (as Patella fimetaria) I thought it had some potential.  What do you think?

On second thought I retract that idea (S. crinita).  It doesn't appear to occur in my range.

Malcolm (and others as well), I wonder if you could have a look at another collection, a very similar--probably the same--species of Scutellinia as my earlier one. A friend just showed me the online Tom.bio tool which is certainly a time-saver, but it gives rise to a few questions.

The new collection...

Apothecia up to 5mm in diameter
Spores from spore drop (in cotton blue): 18-20 x 12-13 (15) µm.
Q value = 1.46
Spore shape: Ellipsoid
Spore ornamentation: "Small to medium often amoebic warts with some interconnections" Question: Would you agree with that assessment?
Asci: 230-250 x 12.5 (17.5)µm
Marginal hairs: 1114-1243 x 32.5-42.5µm
Marginal hair wall thickness: 5-7.5µm
Marginal hair septations: 4-11
Marginal hairs: some bi- tri- and multi-furcate.
Question: When some roots are simple, some bi/tri-furcate, and one or two multi-furcate, one should opt for multi-furcate, yes?
Marginal hairs: With pointed top. Color brown. Question: would you suggest "Hairs of differing length" or any other options? (Though it doesn't seem to alter the top selection of outcomes.)
Substrate: wood.

The automatic result suggests S. olivascens. But when I scrutinize the "knowledge base" synopsis, the data for S. scutellata seems more apt... especially comparing spore shape and size, hair length and other hair features. Am I missing something? What could be weighing the result toward S. olivascens?

Again, many thanks for your help and comments.
