Hi Malcolm

I do not know what P. plicata is.

I myself would call this P. atrata (P. escharodes ss. Zotto in former times).

The latter is surely a collective species - and I am not a specialist in Pyrenopeziza (nor in anything else ...)

Best regards,

Lothar

Hallo Lothar,
Rehm  kannte eine P. plicata, auch eine P.  subplicata hatte er  bei Ruhpolding aufgesammelt.  Im ATLAS sind beide Arten in BY aufgeführt, W. BEYER hat die Art in seiner Pilzflora, in der DGfM- Kartierung hatte sie R. LEFLER auch in der Obpf. Und in der neuesten RL D ist die Art auch aufgeführt. Habe aber auch keinerlei Ahnung, was das sein soll.
Grüße in die Nacht Peter.

Hallo Peter,

als ich schrieb, dass ich nicht weíß, was plicata ist, meinte ich nicht, dass ich den Namen noch nie gehört hätte (das habe ich).

Aber banal aussehende Pyrenopezizen mit banal kleiner Sporengröße an banalem Substrat (Wie es Angelica ist) würde ich ... nun ja, wenig wissenschaftlich ... eben atrata (escharodes) nennen.

Dir auch ganz liebe Grüße und Gute N8

Lothar

Hi Mal,

again me:

you write hogweed - and you write Angelica

istn`t hogweed (only?) Heracleum?

Or is Angelica hogweed, too?

I know a song of the gigantic group Genesis (in former times with Peter Gabriel) from the gigantic album "Nursery Cryme" where you can hear rhymes about the "giant hogweed" (Heracleum mantegazzianum") brought from the Caucasian mountains as a gift  to the Royal Botanical Gardens of Kew. ... I realy love it and consider it one of the best albums ever produced ...

Anyway - what I say doesn`t contribute anything to the question how to call the Pyrenopeziza ... (I still would call it atrata)

Best regards,

Lothar

I likewise don't know what P. plicata is. I only see in my database that the spores are 8-12 (Hütter, Elis & Ellis) or sometimes even 13 µm long (Gremmen). So this would not fit P. atrata.

Whether P. atrata is heterogeneous I cannot say, much morphological variability I do not recall. There are some sequences by Andreas Gminder under the name escharodes and one by Florian Prell/ Ingo Wagner under atrata (FP269), and they all fall together with not much differences, but the clade is not very well delimited.

Thanks for the responses. I was using Ellis & Ellis and the only species fitting was P plicata.
I could see almost no oil in the spores in water and as it does not have large marginal protudings using Declercq it leads to P chamaenerii. This species is shown (in E&E) as growing on Epilobium but Declercq also includes Angelica.
Is this a possiblilty?

I know that only from Chamaenerium in the literature, but I am not sure about its characters, whether it is different from atrata.
