michel bertrandBonjour, Malgré de nombreuses recherches, je n'a
Any help on this one is welcome:
Habitat: On the poroid hymenium of decaying Trametes versicolor.
Macroscopic description:
Apothecia up to 0.3 mm in diameter, especially in the centre with a grey colour (from the coloured Excipulum), waxy. Margin whitish, translucent, smooth. Apothecia very crowded, in parts seemingly forming a confluent layer.
Microscopic description: Asci 48-65 x 5-6 µm, often somewhat stalked, pleurorhynch, IKI negative. Paraphyses filiform, diameter about 2 µm. Excipulum consisting of textura globosa to textura angularis, cells grey-brown with sometimes thickened walls. Spores hyaline, with a big variety in size and shape. Usually assymmetric, often nearly club-shaped, aseptate or one-septate, size ranging from about 7x2.5 µm up to 13x3 µm.
Many thanks,
Stefan
This could be Gelatinopsis fungicola: at least colour, spore form and spore size match very well. Moreover, the substrate of this species is Trametes. The species and the other species of the genus have been extensively described and illustrated by Baral & Marson (2011, Monographic revision of Gelatinopsis and Caloriopsis (Calloriopsideae, Leotiales)).
Eduard
It would be a great opportunity to take the first sequence of a Gelatinopsis! This would be especially important because we have a sequenced undescribed species that could be Gelatinopsis but we are not sure about the genus.
Stefan, you don't have this possibility?
Regrettably, the type species G. geoglossi seems never to have been recorded in Europe.
Zotto
If you dont have the posibility, you can send it to me.
regards,
Stip
I do not have the possibility for sequencing myself. It would be great if you could do it Stip.
I will contact you by Email.
Stefan
@ Zotto, you can occasional advise me on a article ;-)
Stip
I fear that LSu would be helpful in addition to ITS in this case. because closely related sequence are possibly absent so far.
Both of you got an email with a sequence of Gelatinopsis hysteropatellae.
Enjoy,
Guy
although it is not the group I am studying I think it is very much in interest of fungal taxonomy if a sequence of the type species came available, from when is your collection? If you have some macro and microphotos of your finding to share with us would be wonderfull, I have never seen this species alive.
For sequencing we need at least 20 fruitbodies of this size and there is no guarantee for success especially when it is so interwoven with the host.
cheers,
Stip

these are good news but I am surprized about only one apo. Long ago i studied the type and remember there was plenty of minute apos on the Trichoglossum. At that time I did not have a Digicam but I noted there were over 1000 apos! See here my drawing of a sample from 1938.
And as Stip says, we urgently need micro-docus of the vital cells of spores, paraphyses etc. This species somewhat resembles a small Hyalorbilia, and perhaps vital taxonomy could give a hint on its true relationship, or more probably molecular data.
Zotto
Yes, my apologies, I meant to write that I had apothecia of the HOST fungus Trichoglossum bearing myriad ascomata of the parasite. I am looking at my collection now from August, 2011 and find that I actually have two parasitized ascomata of Trichoglossum and a note saying that the parasite fruited on the apothecia and stipes of my collection. Sorry no other data for this one.
Like I said, anyone who is seriously interested in working on this genus is welcome to this collection. I may be able to spare some time and try to recollect (the locality is 45 min north of Boston) and if I am lucky I would be pleased to ship the collection overnight for examination in the living state.
Such an interesting genus and I had no idea there were other species.
Please, let me know if I may be of any assistance.
Kind regards to all - Jason
Anyhow - just an idea! :)
This sounds better :-)
It depends a bit if Guy is willing to do the molecular work, then he could do also the microscopy in living state. It will not be cheap to send fresh material so fast.
If you are interested I will send you our paper on the genus, published in 2001 (I have it only as jpg).
Zotto
Best, Jason
lets wait what Guy's answer is

Stip
Hi Jason,
If you wanna send material, chose the following address:
To the director of the Museum of natural history,
c/o Guy Marson
1a rue Plaetis,
L-2338 Luxembourg-City
Luxembourg
Considering the customs declaration: --- Please send only dry material --- and declare it as "dried specimen for scientific use only". Declare the value of the material as $ 0.00 ("zero"$).
Thanks a lot and best regards,
Guy
