Re: Physcia clementei?

Did you compare your specimen with some of the photographs of Physcia clementei on the Lichens marins website as many of those have similar lobes?

Oomycete - Peronospora chenopodii-polyspermi

I hope its ok to post an Oomycete - Peronospora chenopodii-polyspermi causing noticeable yellow patches on leaves of Chenopodium polyspernum in Dorset yesterday. No idea what the distribution might be as there are no records on the NBN but I doubt if that means much! z Peronospora chenopodii-polyspe...

Re: Two species of Peziza on compost?

Two species of Peziza on compost?

These seem to be two different Peziza's found on woody compost - tentatively are they P. varia and P. vesiculosa? The first (?varia) had spores 20-22 x 12 µm, the second smaller ones (?vesiculosa) spores 16-17 x 11 µm. It was difficult to see whether or not the asci tips of the first were KI +blue, ...

Re: Ampelomyces quisqualis on Podosphaera

Many thanks for the reply Chris, and for your email.
I've come across Eudarluca caricis a couple of times (on Melampsora populnea and M. euonymi-caprearum) but might well have missed or not been able to identify it previously

Ampelomyces quisqualis on Podosphaera

Found on Pyrus communis leaves today and I thought possibly Podosphaera until I looked under the microscope....... Turns out the brown mycelium is Ampelomyces quisqualis, a hyperparasite of powdery mildews z Q 190427 006 Pyrus.jpg z Q 190427 011 Pyrus.jpg z Q 190427 011b Pyrus.jpg z Q 190427-3.jpg z...

Re: Lichenicolous on Ochrolechia parella

Thanks for the reply Chris.

I couldn't understand why I had no spore details but finally managed to find the specimen and realised why - a scrappy collection of rock crumbs with a note on the packet saying "gone mouldy, no spores found".

So not a hope!

Lichenicolous on Ochrolechia parella

I came across this photograph of a lichenicolous fungus on Ochrolechia parella, coastal SW Ireland 2012 and wondered if anyone might have come across anything similar on Ochrolechia to suggest a possible identification? z spC1 1201310012 Och parella.jpg z spC1 1201310012b Och parella.jpg z spC1 1201...

Re: What is the current name for Daisy Rust

Hi Posch - it looks like the answer might depend on the source you use. Here's a link to Bladmineerders where the jury still seems to be out as regards the occurrence of Puccinia lagenophorae on Bellis perennis: https://bladmineerders.nl/parasites/fungi/basidiomycota/pucciniomycotina/pucciniales/puc...

Yes, that's Nostoc - probably N. commune but there are others.......

Re: Help with identification please

Hi Chris - be warned, only taste a very, very small amount as if its Pertusaria amara it is most horribly bitter!

Myxo on Oak leaf

Came across this myxo on an oak leaf today and wondered whether identification (at least to genus) might be possible? Surface was powdery / granular, stipe absent, spore diameter 10 µm. Externally it looked similar to Mike's image of Badhamia macrocarpa but I'm totally ignorant when it comes to slim...
