Re: White growth on ornamental cherry tree

Mike is absolutely correct Compare with for example http://champyves.pagesperso-orange.fr/champignons/autres/Myxo/Enteridium_lycoperdon7.jpg Spring is the usual time for this slime mould to appear - sometimes it will "fruit" on worked wood, window sills etc. When it disappears there will have been n...

Re: A rare? zygomycete on dung

Nobert Heine has kindly got back to me from Germany. He tells me he has been studying dung fungi for 20 years, and has recorded over 300 species, but has never come across Coemansia erecta. So I think it has to be considered rare . . .

Interesting Chris
not being a lichenologist I wasn't (to my shame) aware how frequent the host is: https://species.nbnatlas.org/species/NBNSYS0000018579 . . . . I shall keep an eye out for these Vouauxiella spp. (once I've learnt to recognise the Lecanora :oops: )

Re: A rare? zygomycete on dung

Thanks for the kind comments. Enrique Rubio says it appears to be unrecorded in Spain, and Michel Delpont doesn't know it from France either, although it has occurred there - the type location appears to have been from the Paris area - see:

A rare? zygomycete on dung

I got rather excited when I spotted this tiny fungus on an incubated collection of roe deer dung. Under the dissecting microscope it looked intriguing, and under the compound scope its architectural splendour was revealed - the images scarcely do it justice. It was a case of "I've seen pictures of t...

Re: Exidiopsis calcea query

Hi Mal, From description and images this does look like Exidiopsis calcea. I have two collections of E. calcea, both with spores to 18-20 long, width 5-7.5. Oil drops also noted in both collections. In several seperate collections of E.effusa, spores never reaching these dimensions. Cystidiols can ...

Re: Arum maculatum: a full set

Hi Not easy to see but the Ramularia looks to be OK - I think I can make out the white tufts of conidia. I think the dark markings on the other hand are simple anthocyanin pigmentation, very often seen on Arum maculatum ; a good clue is that thin dark margin to the leaf - again due to anthocyanin pi...

Re: Arum maculatum: a full set

Hi
I won't comment until I can see the pics - not your fault, I fully appreciate, Simon. Do you have images of the smut spores?

cheers

Re: Peziza sp.?

Hello, this is most likely Disciotis venosa. If you have a microscope at hand, you can pick a small piece of the hymenium and squash it in Melzers Reagens (or Luglos solution) -> if the ascus tips turn blue it is a Peziza species. If the ascus tips do not turn blue, it is not a Peziza species, but ...
