Dear friends,

 

last December I collected in the highland cloud forests of Ethiopia. There where a few ascomycetes, among them half a dozen operculate ones.

 

One of them is posing me problems (the others too, to be honest ....):

Macroscopically it looked like a Peziza with a short, thick stipe, the hymenium colour deep violett, the exterior much lighter, rose coloured.

Microscopically the spores with thick longitudinal ridges are surprising.

Judging from the asci, this species should belong into the Sarcoscyphaceae, and the spores hintz towards Cookeina. But the ascocarp was completely without hairs, and the hymenium colour dark violett also is not known in Cookeina.

Has anyone an idea, in which other genus this species could belong?

 

thaqnk you and best regards,

Andreas

Re : Cookeina spec.?

Maybe Phillipsia?

Re : Cookeina spec.?

Hello,

 

ah, yes, of course!

I should have come to that myself *shame*

 

Has anyone a monograph of the genus?

best regards,

Andreas

Re : Cookeina spec.?

Hallo Andreas
I don't think there is a monograph, just treatments from different parts of the world. Here is a paper dealing with Central American species; it may not help you directly, but may give some useful context.

Re : Cookeina spec.?

hi andreas,

this looks like a "classic" p. domingensis to me, because of the relatively few and big ridges (3-6). the most common species. but its a complex with a lot of different forms, especially concerning the colour. hansen, pfister and hibbett made a phylogenetic study especially about the domingensis-complex.
whats about spore-measure?
as you know i'm preparing a paper to p. carnicolor for next zmykol, which was found in a warm-house in nurnberg. so i have some material that i can send you. very important is le gal (discomycetes du madagascar). i think you will have that ...

best

Re : Cookeina spec.?

Dear Chris, dear Dirk,

 

thank you a lot for your helping.

And yes, no matter which key I use, I always end up at P. domingensis. Only thing not so perfect fitting is the pure violett hymenium colour and the pinkish exterior. You can even see the ectal excipulum being pinlish coloured in a KOH preparation in the light microscope.

 

But I will file it as Phillipsia domingensis agg. now.

 

In some moments I will present a Cookeina cf. colensoi :-)

 

best regards,

Andreas

Re : Cookeina spec.?

This might help a little - clearly possibly a widespread taxon . . . .
