I tentatively identified this find as Scutellinia

Two more Scutellinia
Malcolm Greaves, 10-10-2012 01:31
Malcolm  GreavesI thought with a good Key they might become a little easier but it does not seem that way.
Found on a log which had been kept artificially wet. Small at 1.5mm
Spores 17-19.2 x 11.36-11.94 with small warts with noticable connections.
Hairs max 666 x 38  multifurcate.
This leads (me) to S vitreola which does not look much like my find.
Thanks as ever
Malcolm

Adio Malcolm,

Typical hairs bases, typical sporal ornementation and form of spores. In my mind, this is Scutellinia crinita, a young specimen, so that explains the short hairs.
S. vitreola is different.

Thanks again.
When the length of the hairs cannot be counted on as a defining feature it does make it difficult but noone said it would be easy.

Re : Two more Scutellinia
Beñat?
I went back and collected another more mature sample (3mm across). the hairs are still mostly under 650 um (after some searching the longest I could find was 730)
If you are still convinced it is S crinita I will happily log it as that. Unfortuntately the British Checklist (supported by an article by Brian Spooner) has this as a synonym of S scutellata so it will be recorded as that but with a note that I believe it is S crinita.

Thanks
Malcolm

Re : Two more Scutellinia
Adio Mal,

I'm not sure that represents S. crinita. It's not possible because I haven't seen the specimen and it's difficult to see sporal ornementation with just one spore.
In fact, hairs are typical, but other species are possible with this form of hairs.
About your hypothesis, S. scutellata : it's a long work, not finished today for a lot of reasons :
- S. scutellata was the name most used in the past but this is not a common species and it must come to identify specific limits.
- Currently, we have clearly identified S. crinita, very common, and S. pilatii (Svrcek typus + Schumacher's collection + DNA of personal collections from Pyrenees).
- Several other collections (herbaria + personal) refer to something else, which I call "scutellata complex" for now.
- In addition, like you say, Yao & Spooner proposed synonymy (crinita and scutellata), which is not a good idea, in my mind.

But, now, I'm unable to say what is S. scutellata precisely...
It's a long work and we have the same work in "umbrorum" complex and "nigrohirtula" complex...

Thanks again for the comprehensive reply. This can join my growing collection of unknown specimens.
