Distribution of European Pear Rust

I had a conversation last week about how European Pear Rust (Gymnosporangium sabinae) has apparently become much commoner in Cambridge over the past 2-3 years In Notts I've tended to find it whenever I've come across a pear tree, and similarly in Berkshire. It so happens I have two or three records ...

Re: Dual posts - UK Fungi and ABFG/FCT

I can't comment specifically about BMS/ABFG, but dual posting is generally frowned upon. In various other (non-wildlife) forums it seems common practice for someone (usually a moderator) to tag or annotate a post as a dual post. This has two effects: no-one answers the post and further posts will be...

Re: Rhytisma ulmi?

Hi Jenny,

Chris wrote a really informative piece of this a few years ago on WAB: IIRC in response to a query of mine very similar in tenor to yours. One of the biggest losses are many of these in-depth answers from Chris.

Re: Phragmidium rosae-pimpinellifoliae I think..

There was rust on more or less every plant of Burnet Rose in Northern Ireland in June (White Sands Bay, The Umbra, Binevenagh). I've assumed this was Phragmidium rosa-pimpinellifolia, but not sure that my records have been accepted by the NI Fungus recorder. (That being said I managed a few new VC r...

Re: Rust on daisies

These days it's most likely to be Puccinia distincta, see the sections written by Brian Spooner in the FSC Plant Gall book. There was an epidemic of this rust in the 1990s (see http://www.sciencedirect.com/science/ar ... 6208610138).

Re: Thyme-leaved Speedwell growing on rock

It self-seeds from the lawn very well amongst the brick pavers of our driveway, so why not on rocks!

Re: Advertising UK Fungi

It may also be worth posting something like the fungus of the day (or similar) on twitter. BSBI have a publicity officer who is social media savy and there is now an excellent flow of tweets (largely of orchids I havent seen :( ) from wildlife folk. Guardian country diarists, Phil Gates (Durham) and...

Re: Urocystis ranunculi?

It's a gall causer. Had it at Burroughs Wood (VC55) https://www.flickr.com/photos/mausboam/14991477619 and (in your neck of the woods) Tandle Hill Country Park (VC59) last September.

Re: A common smut to look out for

I note my records in SK53 aren't on NBN. I've found it several times at Attenborough Nature Reserve, and on one occasion measured the spores after and NFG Foray.

Re: Taphrina pruni on Blackthorn

It's actually quite rare for the wizened 'pocket plums' to stay until the Autumn: diligent searching will usually reveal one or two. Taphrina pruni in my experience is much commoner on Prunus cerasifera Cherry Plum appearing almost immediately after flowering (mid-April onwards). The fungus causes t...
