Lachnum / Lachnellula

Miguel Ãngel RibesHi again

This another one is 1-1,5 mm, subsesil, in Pinus sylvestris, hymenium yellow-orange, outer surface covert with apparently white hairs. Microscopically it remembers me Lachnellula subtilissima, but it is too small and all the apos are very closed, not completly open at maturity like L. subtilissima.

Thank you,

Miguel Ángel

Cylindrical-fusiform spores.

Re:Lachnellula / Lachnellula
It is incredible, but I have only see one asci, in water, so I don't know it has croziers or not, nor the IKI reaction. It has 47,4 x 6,6 microns.

Re:Lachnellula / Lachnellula
But it has a lot of septated paraphysis, cylindrical, but frequently branched and with several bubbles. This one not branched.

Re:Lachnellula / Lachnellula
This another structure I am not sure they are paraphysis again or hairs.

Re:Lachnellula / Lachnellula
And finally, I have not see a clear hairs. Apparently it has very clear white hairs, but the best image I have obtain about it is this amorphous hyphal mass with external granules.

Thank you in advance,

Re:Lachnum / Lachnellula
Your apos are quite big and open, typical of Lachnellula subtilissima when rehydrated. Also from the substrate there is nothing else to be excpected. Lachnellula subtilissima is variable, having usually hemiamyloid but also inamyloid asci, even the croziers vary. Lachnellula calyciformis has more fusoid biguttulate spores and always inamyloid asci.

You should try a section with a sharp razor blade then you are sure which are the hairs. they must be distinctly rough-warted,

Cheers

Re:Lachnum / Lachnellula
Thanks Zotto, I never had seen so small L. subtilissima...

I made more than ten sections at the margen with a razor blade, taken only "white material", but all the times I only obtain an amorphous mass. The best one is the photo I attached yesterday, so I am very surprised because all the otrher Lachnum sp. hairs I had seen before were very easy to recognize and to make a photo... :( Mistery :)

Thanks again
