discomycete on Viburnum tinus leaves in Portugal
Lothar Krieglsteiner, 24-04-2019 20:25
Lothar Krieglsteiner

... collected 05.04.2019 in the Algarve, nw. of Loule, Algibre river east of Algibre. The leaves with the discomycete partly hung in the twigs, partly lay on the ground built of pebbles in the dried out riverbed.


The discomycete is quite peculiar in my opinion - mainly because of its very large paraphyses (compared with the small asci and spores) that are strongly lanceolate and have a conspicuous vacuolar body. The spores are about 4,5-5,5/1,5-1,8 µm, the asci IKI-positive (blue) and likely (I became not quite sure) with croziers. The excipulum of textura prismatica ends in elongate hairs that - in my opinion - show excrescences similar to that in Mollisina.


Who knows such a discomycete or has any idea? On the substrate Viburnum tinus I know Trochila tini that is very different - I once showed it in this forum.


Best regards, Lothar

Re : discomycete on Viburnum tinus leaves in Portugal
Esto es una Hysterostegiella, aunque ahora no sabría decirme más.
Se ve bastante similar a H, dumeti y H, quercea, aunque éstas tienen secreciones resinosas en forma de espiral en los pelos.

Hysterostegiella on Viburnum tinus leaves in Portugal

Hola salvador
muchas gracias Nunca he tenido una Hysterostegiella, y tengo curiosidad por ver si se puede encontrar la especie.
Saludos cordiales, Lothar

Re : discomycete on Viburnum tinus leaves in Portugal
Indeed Hysterostegiella, but that genus is a mystery. I suppose there is not much host specificity in some species.  At least I see no real difference to juniperina and lauri in my folders. Also the Smilax sample by Pablo Chacón (http://www.ascofrance.com/search_forum/9180) is very similar, but here no photo of the hairs exists.

I don't see Mollisina-like outgrowths, rather I think about granular deposits.

Re : discomycete on Viburnum tinus leaves in Portugal
Veo las hojas demasiado largas y estrechas. ¿Podrían ser de Laurus nobilis?
En ese caso podría ser H. lauri.

Éste trabajo quizá le pueda ayudar.

Re : discomycete on Viburnum tinus leaves in Portugal
Beautiful collection! Looks there is no sequence for the genus. Not in Genbank not in the unpublished paper of Johnston. So if you have the oportunity you should try to get sequences to see the phylogenetic placement of the genus.
Best wishes,
Luis

Re : discomycete on Viburnum tinus leaves in Portugal

Hello together,


thank you very much for all of your contributions.


Yes, I also think the Smilax collection is very similar - and Smilax is a common plant in the surroundings of my find. For the moment I tend to call the collection H. cf. lauri - even if I don`t think the leaves are Laurus. There was Viburnum tinus growing (and flowering), and no Laurus visible.


No - I have no opportunities for DNA-investigations. If somebody wants to do this, I can send him/her a part of the specimen.


Best, Lothar

I also cannot see a sequence of the genus. Maybe I planned a collection to send, but not sure. There is little doubt that the genus must belong in Cenangiaceae.

I am not sure when I will send the next batch of samples for sequencing, maybe only in half a year....

If you have interesting collections of Leotiomycetes like this I can help you. My email is lquijull@gmail.com. You can write an email and I can help you with that.

Re : discomycete on Viburnum tinus leaves in Portugal
Hello,
I would like to include this very interesting species to our Cenangiaceae multigene study. Until now, I have any fresh material of this genus. If you like to share some apos, it will be great to analyse together with Cenangiaceae we have studied.
Best wishes, 
Kadri

Re : discomycete on Viburnum tinus leaves in Portugal

Hello Luis and Kadri,


so - I should send some apos to Kadri - please tell me your post-adress (I know I once had it but ... - you know :-). Please write lo lkrieglsteiner@t-online.de">lkrieglsteiner@t-online.de


@Luis: thanks a lot for you generous offer. I perhaps come back to this one time.


Best regards, Lothar
