Lachnum sp. on leaves of Berberis vulgaris

HI to all


This a an older friend of us that grows persistently on previous years leaves of Berberis vulgaris at the montane/subalpine regions of Asturias.


I'd like to know your opinion about it that not fits well with any species known by us


Thanks again

Re : Lachnum sp. on leaves of Berberis vulgaris
Dear Enrique,

This is very close (but still rather distinct) from ours Capitotricha from other Berberis species and it could be very interesting to join our material and continue the research together. We were very near to close this case and started to think towards the publication! It is nice to know about closest relative on time! Please use our e-mail for further communication on this item if you're interested!

Cheers,
N.

I believe that I and Anne Molia has collected the same species as shown here on Berberis vulgaris leaves on the coast of Oslo Fjord, Norway. Material can be forwarded if you are interested

Thank you very much for your kind offer, Neven, but we are making a paper on the mycological flore of Somiedo and we would like to decribe this species in this work


 


Regards


Enrique

Re : Lachnum sp. on leaves of Berberis vulgaris
Hi both of you

I want to say that I am not sure whether this species can be accomodated in Capitotricha. I also see similarities with Lachnum rhytismatis/microsporum.

I looked in my database. Two species are found on Berberis with such spores:

Dasyscyphus albopileatus: differs in rather long apothecial stalks and no crystals mentioned. Also hairs apically not at all widened, so probably not closely related.
(Haines et al. 1980, Nova Hedw. 32: 699). 

Lachnum subauratum: has stronger clavate spores and also no crystals mentioned. Also here the stalk is said to be rather long (élancé). Asci are said to have croziers.
(Raitviir & Garcia 2000, Bull. Soc Myc. Fr. 116: 155)

Probably the two are different from yours, but I am not sure.
