Lost and found rust

Post by alindsay » Sun Jul 31, 2016 3:10 pm

Inspired by the Kew Lost and Found project, I took myself off to Houghton Regis Chalk Pits nature reserve, Bedfordshire, where there are thousands of Gentians at this time of year, ranging from Chiltern Gentians, through hybrids to Autum Gentians ...... and there it was, all for the want of looking, what I think, is possibly Uromyces gentianae.

I cannot do the microscopy, but it looks very similar to authoritative photos of this rust. I am drying samples to send to Kew for confirmation.

So not lost, just not found if no one looks.

Good find - hope Kew are able to confirm! I've been looking for Puccinia cladii and Chrysomyxa pirolata in Glamorgan so far without success. Also a few other fungi on LAFF list. Hypoxylon fuscoides Woodwart on Alder has been found by one of the Glamorgan Fungus Group and confirmed by Kew so we have a success!

This is surely the rust - excellent stuff. I suspect Gentianella germanica (and the hybrid) might well be new hosts in the UK? Unless more recent finds than those listed on FRDBI have been made. I assume it was on those as well Alison? those broad leaves look to be those of G. germanica . . .
best wishes

PS I was going to say "welcome to UK Fungi" but see you have been a silent partner for a while ;)

Hi Chris

Glad to be back in the fungus (or is that fungi :D ) world.

The rust was on all the types of Gentians, but not every plant. In fact the majority were rust free.

Regards Alison

Kew are on the case to confirm the identity of the rust found in Houghton Regis, grid ref TL 00528 23698 and they are very hopeful.

Meanwhile, today' I found more rust on Autumn Gentians at Knocking Hoe nature reserve, Bedfordshire, grid ref TL 13068 30922. Sample being prepared to send to Kew.

Looks like it thrives in Bedfordshire.

Brian Douglas from the Lost and Found project at Kew has confirmed the finds at TL 00528 23698, Houghton Regis Chalk Pits on Chiltern Gentians, Hybrids and Autumn Gentians and also at TL 13068 30922, Knocking Hoe on Autumn Gentians, both sites in Bedfordshire.

The FRDBI will be up dated shortly.

I have also been looking at several well known Autumn Gentians sites in Buckinghamshire, looking at hundreds of plants, but found no signs of infection.

So pleased to be helping the growth of knowledge in this field.

Wonderful stuff Alison! How strange that it has not been noticed before - scarcely unknown sites. That Houghton Regis quarry looks fabulous in the photo here http://www.houghtonregis.org.uk/houghton-regis-quarry - positively Mediterranean under that blue sky . . . .

Bedfordshire Wildlife Trust only took on the Houghton Regis chalk pits site a couple of years ago, so it is now safeguarded from the motor cycle lunatics. Hopefully, the flora & wildlife will now flourish.
Rather than the Mediteranean, it looks to me, more like being on the moon, see photos!!!
However it is 23deg in S Bedfordshire today, so maybe you are not so far off.
