Bernard CLESSEBonsoir à toutes et tous,J'ai trouvé ce matin ce
I am working with Zotto in an important manuscript in order to finish my PhD, we are trying to delimitate a new family, and we are reviewing several genera, but we would like to include several types, but it is not easy to find them. I would like to know if somebody can help me to find where is deposited the Types or Isotypes of the following species, and if I can request in loan:
Claussenomyces prasinulus
Claussenomyces atrovirens
Can somebody help us?
Zotto told me that C. atrovirens type is deposited in Leiden, but this type cannot be requested in loan, only can be examinated there, somebody know a mycologist in Leiden, or know an isotype that I can request in loan. Now, I cannot travel to review the morphology of this species.
About C. prasinulus, I have trying to find the type in different herbarium that I usually consult, but any of them have type or isotype.
Thanks in advance,
Luis.
since Peziza prassinula was described by Karsten in 1869 the type material, if preserved, should be in Helsinki (Luomus).
Regards
Martin
There's this specimen of C. atrovirens at Kew with some sort of type status - maybe real, maybe not! I'll have a look for you when I'm back from fieldwork on Monday.
http://apps.kew.org/herbtrack/accession/30943
Edit: I suspect for now that it's a duplicate of the holotype of Claussenomyces hydnicola, which is currently a synonym of C. atrovirens.
Cheers,
Brian
Hi Brian, also yesterday, I saw this information in KEW herbarium, C. atrovirens (30943 as type) and I wrote to Begoña Aguirre-Hudson, to see if it possible to have this sample. In Korf and Zhuang drawing of C. hydnicola, primary ascospores appear only with transversal septa, cylindrical, and secondary ascospores are clearly alantoid. C. atrovirens, in the concept that I have has primary ascospores with transversal and longitudinal septa, clavate-fusoid, and secondary ascospores are straight more or less cylindrical to ovoid. To be sure if they are synonyms it will be necessary study the morphology of both types, but I have specimens that I collected under C. hydnicola and I think it is a good species.
Thanks to both!
from KEW I received the following data:
Collections K(M) 30943 and K(M) 30945 have been annotated respectively as type of Patellaria nigra (=Claussenomyces atrovirens according to Nannfeldt) and as authentic for Belonidium clarkei in Brian Spooner's hanwritting (=Claussenomyces prasinulus according to T. Iturriaga).
Then I do not believe they are useful for the study that I am doing.... :(
