Do you know this fungus? I have to say spores are fusiform with 45-60 micrometer long and Asci are cylindrical?.

Re : unknown discomycete

Hi Reza,

It looks like a Microstoma and size of spores could correspond to macrosporum but whitish apothecia is a special characteristic. Bad exposition ?
I have the Harada article if you want.

Re : unknown discomycete

Hi Benat
Thanks for reply.
Yes, there are some differences with Microstoma floccosum. As you see, color of cups are truly white to cream, also hairs are just in margin of cup and NOT in all exterior surface.

Re : unknown discomycete

Hi.
Where did you found it ? When ?

Re : unknown discomycete

Hi
I found it from South Caucasus forests in North of Iran, in fall (september and October).

Re : unknown discomycete

It may be Boedijnopeziza insititia??

Beñat Jeannerot, 11-07-2011 22:27

Re : unknown discomycete

Hi Reza,

Sorry for hairs, I have seen with speed and no attention. Sorry.
Perhaps, you are right.
But it's certainly a species of Cookeina, C. insitiata, proved by phylogeny of this genus (see Weinstein & Pfister, 2002).
Your fungus seems to be very closed to this taxon.

Re : unknown discomycete

Salut Benat,

Tu es sur que la combinaison Cookeina insititia existe ?
Par contre il existe bien :
Microstoma insititium (Berk. & M.A. Curtis) Boedijn 1951 Sydowia 5(3-6): 212

Guy Garcia, 11-07-2011 23:49

Re : unknown discomycete

Tu as raison c'est une combinaison de Kunze !

Beñat Jeannerot, 11-07-2011 23:55

Re : unknown discomycete

Adio Guy,

Oui, c'est dans l'article de Weinstein sur la phylogénie des Cookeina.
J'attache une capture,

Re : unknown discomycete

Oupss, tu as répondu entre temps, désolé.

Reza Shaian, 12-07-2011 05:57

Re : unknown discomycete

Hi Benat and Garcia
In monograph of Cookenia (Iturriaga and Pfister 2006), there is Cookenia insititia (Berk. & M.A. Curtis) Kuntze, but in Index of fungi and Mycobank, we cannot see it !!! and just there is Boedijnopeziza insititia (Berk. & M.A. Curtis) S. Ito & S. Imai 1937 as valid taxon.

Guy Garcia, 12-07-2011 08:03

Re : unknown discomycete

De nombreuses combinaisons réalisées par Kunze dans son "Revisio generum platarum..." (1891-1898) sont encore absentes de l'Index of Fungi.

Les ouvrages de Kunze sont disponibles sur le net.

Amitiés, Guy

Re : unknown discomycete

Taxonomical position of Cookenia insititia / Boedijnopezizeae insititia is ambiguous.
But, is my fungus C. insititia? I read species descriptions, but I feel some differences (such as spore size).
