A small group of this Scutellinia was found on wet and rotting wood in a local woodland.Only 5mm across with pale brown hairs up to 830 x 25 walls 4.9
The spores are broadly elipsoid (18.9)19.75 (21.2) x (13.8)14.92(17.4) with quite large warts some confluent.
I think this is S olivascens.
Thanks for you thoughts.

Re : Scutellinia olivascens
Hello Malcolm.
Could you check the width of the hair? They seem narrow on your photo. Also, have you observed only a kind of hair?
The ornamentation of spores actually resembles S.olivacens.

Re : Scutellinia olivascens
Hello Michel
I have taken samples of the hairs from the most mature fruit bodies and although they are the right length and "s" shape I can find none of the much thicker hairs I have seen in S. olivascens before (or what I took to be olivascens). The widest I can find is 28um.
The receptacular hairs are little different from the marginal ones just smaller.

Re : Scutellinia olivascens
The underside of the apothecia is quite pale which is something I have seen noted for olivascens by Benat.

Re : Scutellinia olivascens
I did not know that detail interesting signaled by Beñat. I believe that indeed you can go to S.olivacens.
