Re : Geoglossum second try
Hi Malcolm:
is very difficult to give an opinion with only those data. Macroscopic characteristics? Asci reaction with IKI?
Dirk, your photography is a different species, perhaps G. cookeanum.
Regards.
Sabino.

Re : Geoglossum second try
Yes Dirk, but in the typical form, the parahyses of G. cookeanum can be highly variable. G. barlae ss. orig. = G. cookeanum, see Benkert.
Regards.
Sabino.

Re : Geoglossum second try
The descriptions of the paraphyses of these two G "barlae" differ so much we must be talking about two different species.

Re : Geoglossum second try
Yes Malcolm, clearly. The interpretation of Priou (and most authors) is another species.

Re : Geoglossum second try
Thanks Sabino
We will have to wait until all these species are included in a new key.

Re : Geoglossum second try
Hi all,
my key 1992 is of course obsolete after the good job by Arauzo & Iglesias. In Errotari 2014.
When I look my plate, puff! I learned to draw after... then Zorro is arrived, pardon when Zotto is arrived
At this time, , the authors for exemple Nannfelt 1942, Maas-Geesteranus 1956 and Benkert 1976 give barlae with hooked- crozier-like paraphyses. But after 1996 Benkert synonymises it with cookeanum, we need to give a new name for the specimen with such paraphyses.
In his key Sabino brings new features to separate Geoglossum species, IIK reaction and the extern cells shape of sterile part, nethertheless , with these characters, we are often "assis entre deux chaises " French lession !

Re : Geoglossum second try
Hi All
I see a lot of Geoglossum cookeanum with the paraphyses consistantly multi-septate, slight constriction at the septation, and often with capitate heads. The third cell from the apex is often elongated but I have never seen it distorted as depicted in some images of the perceived G. barlae.

Is the "Sabino" key available online?

Re : Geoglossum second try
Yes clearly cookeanum. look on sterile part you have the same cells on ectal part.
