Bonjour Please can someone help me with this id

Peziza on woodchip (Rhododendron)

Pollard Adam, 08-06-2015 22:02

Bonsoir!

Can anyone help ID this Peziza please?
Spores are smooth 15-18 x 9-10µm. No guttules.
Asci only blue at very tip in Melzers.
Paraphyses slender, sparse and fragile. Simple, and septate with slightly inflated ends.
The brian Spooner key takes me to P.micropus, except these fruit bodies were very large (up to 150mm diameter)

Re : Peziza on woodchip (Rhododendron)

In my opinion, the best option is P. varia, but it would be useful to see content of paraphyses (in water) and to provide information on the structure of the flesh.

Re : Peziza on woodchip (Rhododendron)

I agree, your Peziza is certainly consistent with Peziza varia. With P. varia the lower and middle cells of the septate paraphyses can be up to 20 microns wide in a high moisture environment. The apical tips are slender and slightly clavate.

Re : Peziza on woodchip (Rhododendron)

Hello Nicolas,
can you explain or tell me literature on the complex Varia - repanda, cerea incl. muralis and micropus are difficult to separate and maybe the same. Where can I learn more?
Regards from Lothar (I fear I am not fully actual here ...)

Re : Peziza on woodchip (Rhododendron)

thank you very much!

I always thought that it is highly arbitrary to divide the varia-complex. Very nice!

Best regards from Lothar

Re : Peziza on woodchip (Rhododendron)

Thanks / Merci to your help! Perhaps it was hard to see in the photos, but none of the paraphyses were swollen except the tips. This is why I ruled out P.varia as I assume monoliliform refers to swelling away from the tip.

Re : Peziza on woodchip (Rhododendron)

.. yes, the "old" P. varia ss. str. was defined with moliniform paraphyses. But this character, as others, seems to be highly variable and influenced by environmental conditions.
