Alex AkulovDear colleagues
Below are pictures of some samples of Orbiliaceous fungi.
Please advise me which of them - are trivial, and which samples should pay more attention in the nearest future. To overview quickly about 400 packages is hardly succeed, so I want not to waste time on simple species :-)

Thanks in advance,
Alex

Re : Orbilia/Hyalorbilia
Hi Alex,
first 5 & 6 & 24 look Mollisioid to me, 12 can be Pezicula but you should test microscopy, asci IKI red and rather large multiseptate spores, if not also Mollisioid.
25 1 Hyalorbilia and 2 Hyaloscypha, 13 Hyaloscypha too, if hairs blunt and with resin, asci arising from croziers - aureliella the most common one on Coniferous wood.
among the rest is a lot of inflatula or fusispora.

cheers.

Re : Orbilia/Hyalorbilia

N4 - spores immature, bacilliform, very small: 2,3-2,4 x 0,4-0,5


N5 and N6 - Mollisia spp.


N7 - ? Orbilia xanthostigma (see photoes below)

Re : Orbilia/Hyalorbilia
I assume you have a mixture here: the macro probably shows Hyalorbilia inflatula, but the spores look for me like belonging to Orbilia aurantiorubra (an orange-red fungus).

Re : Orbilia/Hyalorbilia
I also think you have mainly H. inflatula: 1 3-4 8-10 15 16 (why fusispora?), 21

perhaps 11 is worth to check, or is also inflatula, likewise 23 or 25
 
and O. leucostigma (= delicatula): 7 14 17 18 20

22 is difficult to say because only 1 apo

Microscopy is now quite worse because you dried your specimens. Much better would have been to keep them fresh, but I know it is difficult with so many samples.

Re : Orbilia/Hyalorbilia
Dear Zotto 
Thank you for help! Comparing the data about samples, your comments to them, as well as files with descriptions of species that you have provided, I began to understand a little bit. I'm still familiar with discomycetes unsufficient, but would like to know more about them.

Can I ask you to send my file with your publication "Monographic revision of Gelatinopsis and Calloriopsis"?

Please tell me where were published the data about synonymy of names O. delicatula, O. xanthostigma and Orbilia leucostigma? In Mycobank and Index Fungorum indicated that there are three separate species.

Tomorrow morning I will try to overlook samples N 11, 22, 23 and 25.

Grateful before,
Alex

Re : Orbilia/Hyalorbilia
Hi Alex,
you should have the Gelatinopsis file from me already.
n12 is clearly no Pezicula, about the larger spores i think they are the few ones that are still alive because they still have their oil guttulation pattern.
cheers,
Stip

Re : Orbilia/Hyalorbilia
Hi Alex

I think the Gelatinopsis paper is on my DVD, do you have the DVD?

The synonymy of the three Orbilias you mention will be publshed in our monograph. Ellis & Ellis separate between the white (leucostigma) and yellow form, but there is hardly any reason to do so, because the microscopy is the same, and I have cases where both grow densely intermingled, though this is not a proof, I admit.

These names have been applied in very different senses. We lectotypify O. leucostigma because it is the type species of Orbilia, and abandon to use xanthostigma, for which we so far do not intend to make a lectotypification (it will become a nomen dubium).
