Adio Zaca,
How are you ?
For this collection, impossible to say without spores in BC...
Probably around nigrohirtula complex, but spores seem to be not mature...

Hi Beñat,
I hope everything is right with you as well.
I suppose that by BC you mean "Bleu de Crésyl". I posted some photos of it in the 4th group; The stain was not very effective; Maybe I have to let the blue act for a litle longer. Anyway, I will do it again (in the last apothecia I have, the collection was really short) and post here the results.
Best regards,
zaca

The usual stain for Scutellinia spores is Lactophenol Cotton Blue.

Re : 2014-02-07-Scutellinia
Thanks, Malcolm, for the warning.
But, I experienced the same problem with Lactophenol Blue than before with Crésyl Blue, the stain is poor and is unevenly distributed. I upload the result of this try.

Re : 2014-02-07-Scutellinia
Hi Zaca
but as Beñat has pointed out the spores are immature and therefore cannot be of any help. See if you can make a spore drop - with a (thin) marker pen draw a small circle on a microscope slide; turn the slide over and place the hymenial surface of the Scutellinia directly over the circle.
If you leave that for a good period of time you can check the dry microscope slide for ejected (mature) spores in the area within the circle under the compound microscope at x100 or x200; if you see spores, mount in Cotton Blue in Lactophenol, heat gently and show the results.
I hope Beñat does not disagree too much with this procedure I often use . . . .

Re : 2014-02-07-Scutellinia
Thanks, Chris,
for your detailed explanation that certainly will be helpful in future.
Unfortunately this time it didn´t work: in fact, after an entire day I was not able to see any spore. The material was already very scarse.
