Lasiobelonium variegatum?
Garcia Susana, 28-01-2014 13:10
Hi

I found these apothecia growing on Hedera helix.
Hairs to 140x4.5um. thick-walled, hyaline and finely encrusted apex.
Sizes asci 40-48 x 4.5-6um. IKI +. croziers +
Lanceolate paraphyses, x 3-4.5um


I think it could be Lasiobelonium variegatum, but I would like someone to confirm or reject it.


thanks, greetings


Susana

Re : Lasiobelonium variegatum?
Hi Susana
Was it o a branch on the ground? Or decorticated and still attached?

I don't think that it is variegatum. Could you look near the base of the apos whether the hairs are straight also there? L. variegatum has strongly undulating hairs.

Hi Zotto

It was a small branch, which was on the ground, detached.
He still had the bark, but was very damaged
I have noticed that the hairs on the basal part are straight.

Re : Lasiobelonium variegatum?
Very unusual that the marginal hairs are ochre-brown and those on the lower flanks hyaline!! 

This is impossibly L. variegatum. 
I see some similarities  to Lasiobel. pseudocorticale, but that species is on coniferous wood.

Re : Lasiobelonium variegatum?
Hello Zotto

The last photos I sent was not much seemed at first. It is true that the hairs appeared hyaline (not only the basal, apical too). Do not know that this may be due: they are losing the pigments, they were contamination ...
I have returned to rehydrate apothecia and I looked under the microscope. I send new photos to see if you can conclude anything more.


Thanks,


Susana
