Re: Parmotrema robustum?

Thanks Neil, I just thought it worth asking as those thallii just looked larger and a bit different but no specimen or measurements

Re: Mixtoconidium canariense on Ramalina lacera?

Just heard back from Javier Etayo - "yes, no doubt, it is Mixtoconidium insidens, really a good finding".

I've a couple specimens so I'd like to send one to Kew (who should I contact?) and one to Howard Fox at the Botanic Gardens, Dublin

Parmotrema robustum?

Four different thallii from Co. Limerick, Ireland on a wooden table and chairs that had been in a small orchard for 30+ years - but I had no books or chemicals with me and unfortunately didn't collect specimens! Could they be Parmotrema robustum? w Parmotrema Q1 1909 Q1.jpg w Parmotrema Q2 1909 Q2.j...

Re: Mixtoconidium canariense on Ramalina lacera?

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...

Mixtoconidium canariense on Ramalina lacera?

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)...

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!
