Spore size is a bit large but I suspect L. subtilissima.

Re : Lachnellula subtilissima ?????
Hola Zotto.
la mayoria de esporas esta entre 8--10 x 2,6--3, luego hay algunas que llegan a 12--13 micras,
Que otra opcion podria acercarse ????

Re : Lachnellula subtilissima ?????
Hi Zotto,

if I see an IKI-reaction of the ascus porus at all, it is blue in picture no. 13. Shouldn't it be a hemiamyloid reaction for subtilissima (red)?

Martin

Re : Lachnellula subtilissima ?????
I see no other option for your fungus.

What Martin says is probably because your Lugol is yellowish rather than red-brown, i.e. diluted. Then you get blue in that species (type RB, blue at low concentration). 

I attach my key to the species of Lachnellula.

Re : Lachnellula subtilissima ?????
Yes you are right Zotto. Rafael's IKI-pictures are very pale and the iodine concentration possibly too low.

Regards
Martin
