Lasiobelonium corticale?

William SlosseCould this be Lasiobelonium corticale?

I have a slight doubt because of the pointed paraphyses.

Thx for your meaning,

Re : Lasiobelonium corticale?
Hmm, the spores are regrettably too unsharp. Spore size would be o.k. but spore shape not so (should be more heteropolar), and spore contents also not (should be full of oil drops).

With a sharper spore photo this would be better to say.

Re : Lasiobelonium corticale?
Thx for your remarks, Hans-Otto.
I toke a new sequence of pictures.
The free spores seems all to be not hyaline and scarcely filled with drops. Most of the free spores are germinating, perhaps that's a reason?
The spores into the asci seems to be filled with many drops.
Concerning the heteropolar shape, I must admit - eager to learn - that this doesn't ring a bell by me.
I hope this pictures are more usefull for you.
Regards, William

Re : Lasiobelonium corticale?
Ah, what is also missing is the IKI reaction, sorry. Some species react red, others blue.

Heteropolar means that there the spores are attenuated towards the basal end, narrowly clavate. Not here.

The pic with the single large ascus shows non-septate spores with a few drops only. This ascus is alive and mature, and the spores within are representative.

You should also look at the hairs on the lower side, in order to exclude L. variegatum which has strongly flexuous hairs there.

Do you have any idea of the substrate?
William Slosse, 13-03-2017 22:43

Re : Lasiobelonium corticale?
The substrate is an old branch of Salix cinerea in an very moist dunedepression.
Can I use Meltzer or KOH instead of IKI?
Hans-Otto Baral, 14-03-2017 07:41
Hans-Otto Baral
Re : Lasiobelonium corticale?
well, I should say no, but you can try WITHOUT KOH, and afterwards after KOH. If the result is very different (pale vs. deep blue) then we can conclude that it would react red in IKI.

Re : Lasiobelonium corticale?
Hallo Hans-Otto,

I present here some pictures of the fruiting bodies + some pics of the hairs on the lower side.
L. variegatum?

Re : Lasiobelonium corticale?
Yes indeed, these pics clearly point to L. variegatum!

Re : Lasiobelonium corticale?
Thx for the affirmation, Hans-Otto.
Seems to be a very rare species in our region!

Sincerely,

Re : Lasiobelonium corticale?
It is actually a common species, but I do not know its distribution.
