Many thanks for the reply Neil. Those conidia were examined under the microscope in a drop of K so I've just done another in water but similar measurements - 11-15 x 3.5-5 um most c12.5 x 5um, microconidia present 5-6 x 1. The conidiomata size in the linked paper is much larger than that given in th...

Lichenicolous on several Ramalina lacera thallii on a Horse Chestnut in Co. Limerick, Ireland. Conidia abundant, 1-septate 12.5-15 x 5 µm. Is this Mixtoconidium canariense? From the lichenicolous draft keys: "Conidia 1-septate, ellipsoid, often slightly constricted at the septum, 10-13 x 3.5-4(-4.5)...

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?

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...

Thanks Chris - my notifications must have gone awol as I hadn't realised you'd replied. It was compost from municipal green so heaven only knows what was in the mix!

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, ...

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

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...

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!

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...

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.......
