Scutellinia minor?
Chris Johnson, 06-06-2014 14:20
Greetings,

Found in moisture-retentive calcareous soil.
Apothecia up to 8mm across.
Hairs brown at the rim, yellow to hyaline tipped lower down. 330-625 x 26-40 microns, mostly 3-4 septate. Predominantly simple rooted.
Spores from spore-drop: 19.2-20.9 x 18.5-20.1 microns, tubercules approximately 1 micron tall, in cotton blue (small sample)
Asci 276-288 x 29-37 microns
Paraphyses 320-330 x 4-6, clavate apices 10-12 microns across, several bifurcated near the apex.
This keys out to Scutellinia minor with Schumacher, but it's rare in Britain.
Any thoughts or other suggestions welcome.

Regards,


Chris

Re : Scutellinia minor?

Chris, can it als be the Scutellinia legaliae? I had a couple of them overhere

Re : Scutellinia minor?
Hello Hannie

Thank you for considering this for me.

According to Schumacher, S. Legaliae has 3-5 µm long spines which far exceed my measurements.

Re : Scutellinia minor?
I don't recognize spore ornamentation of S. minor. In this species, warts are more heterogeneous and less dense.
S. barlae and S. hyperborea have hairs < 400 µm.
What is the height of warts?
Chris Johnson, 07-06-2014 09:50
Re : Scutellinia minor?
Hello Nicolas

The warts average 1 µm in height (I called them tubercules in my original message).

The Schumacher key also took me to S. hyperborea but it's currently unknown in Britain.

Regards,

Chris

I can't add much other than to say it has not got the same spores as this S legaliae example. It seems to fit in all physical aspects of S hyperborea and it is only the habitat that is (partly) wrong.
Just because it has not been found before in the UK does not mean it is not here.

Thanks for your thoughts.

I had eliminated S. legaliae on the basis that the spores were wrong, and the shorter hairs and habitat really exclude S. barlae.

This leaves S. minor and S. hyperborea and Nicolas's experience with S. minor suggests the tubercules are not correct.

Re : Scutellinia minor?
Just a minor update on this specimen.

I have taken a larger range of measurements of the hairs and am unable to replicate the 625 µm in the last series, which must be regarded as exceptional.

The new series: 240-496 x 19-30 µm. Me + 388 x 26 µm.

I don't think this alters the position we are at.

Chris
