  1. Sadly no, Harry passed away a few months ago. .
  2. Ta Mick Wee little stonechat .
  3. Yeah that's a good one, stands out nicely in the landscape as it sits on a hill. Here's a version of it I took a few years back .
  4. Cheers Paul, Lunge was a tame efort really Matt's an inspiration, has travelled through Africa and Canada taking amazing wildlife images. One to watch as his talent and career take him across the Natural world. Can see him presenting at some point. Hampstead Heath | Award Winning Wildlife Photographer | Matthew Maran .
  5. Agent Arb and I went to the launch of Matt Marran's stunning new book yesterday which is jam packed with images taken over 4 years across the seasons on Hampstead Heath. An absolute pleasure to have played a small part in helping Matt acheive his goal, by getting him access to being at height for some of his images and for showing him some of our great trees and fungi. Here's a small selection of some of the images across near 200 pages of what is a very fine book. Last image is Matt's shear relief at coming to the end of an epic photographic journey. I learnt loads about photography along the way and owe Matt a debt of gratitude. Can't recommend this book highly enough. Even if you don't know of Hampstead Heath, it portrays the natural cycles here in London's urban countryside brilliantly, and is a really nice book for anyone who appreciates the natural world .
  6. Brown is ok, but yellow is really mellow man Go find some and report .
  7. Oddly enough, I found something that has very similar X.f symptoms (outer leaf necrosis) on a grape vine just today. Will be sending a sample to Alice Holt. We'll be focusing on X.f as well during this summer's Ceratocystis platani surveys across the London Boroughs. .
  8. Not entirely sure, but would look at the cup fungi, something like Paxina leucomelas. May even be desiccated Sarcoscypha Possible that it's come with the trees from the nursery. .
  9. Thanks for the post John, very useful. Though no Xylella fastidiosa on the Observatree Signs and Symptoms Calendar ? .
  10. Mmmmmmmmm, reminds me, should have a cup of cocoa .
  11. It won't be the primary agent that's caused the dysfunction. It's there as a saprophyte on the deadwood volume. .
  12. Technically it's Arbtalk's 'splendid fungi directory' Jules, but I appreciate the sentiment. Like a lot of the species listed on the directory, the information is garnered by looking through as many of the usual text books and resources I have at hand. This then gets backed up by field observation over the last 10 years or so. Pretty much all the texts state that it's a saprophytic fungi. Lonsdale, Butin, Mattheck & Webber etc.... A couple of these talk of it as an opportunist, invading considerably weakened trees. This is generally where I see B. adusta develop, specifically in circumstances such as directly after fire damage, branch failures, large prunning wounds and more often than not on dead standing trees where there are root issues. I think it chases/invades dehydrated wood volumes. .
  13. Brackets in the top two images squidgy Andrew? If so, I'd imagine these are Ganoderma resinaceum .
  14. Yep, Xylaria for the first one, but may be X. longipes rather than X. polymorpha. X. longipes is generally more slender. Second looks to be Bjerkendera adusta, the smokey bracket. .
  15. Interesting pattern of decay and dysfunction in this pond side sycamore. We had to raise the canopy for access (which will make it more hospitable to bats) The base of the stem and the cavity have fruiting bodies of Kretzschmaria deusta The disc was taken from a collar of a side branch near to the top of the cavitation. .
  16. I bet Dire Wolves could hose a bracket at 2m Wouldn't be at all suprised if your hound could do it .
  17. Depends entirely on whether it's been marinated in 'essence of canine' .
  18. Yep, as both Paul, Matty and OakStag have already confirmed. Surprised you've not come across it before Mike, particularly when you were working in the UK back in the day. Laetiporus sulphureus - Chicken of the wood/Sulphur Polypore - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists Have you get the Arbtalk Fungi App? .
  19. Wiki has it listed as Cerioporus squamosus and says its been named so since 1886 https://en.wikipedia.org/wiki/Cerioporus_squamosus The British Mycology Society lists its taxonomy here.... Species data - British fungi Polyporus squamosus (Huds.) Fr., Syst. mycol. 1: 343 (1821) Polyporus squamosus f. erectus anon. Boletus juglandis Schaeff., Fung. Bavar. Palat. 2: 101 (1763) Boletus testaceus With., Bot. arr. veg. 2: 770 (1776) Boletus cellulosus Lightf., Fl. Scot. 2: 1032 (1777) Boletus squamosus Huds., Fl. Angl. Edn 2 2: 626 (1778) Boletus rangiferinus Bolton, Hist. fung. Halifax 3: 138 (1789) Grifola platypora Gray, Nat. Arr. Brit. Pl. 1: 643 (1821) Polyporus rostkovii Fr., Epicr. syst. mycol.: 439 (1838) I haven't heard of any name change, so I stick with Polyporus squamosus .
  20. Is it 'poor' Paul? Any crown symptoms? .
  21. I would tend to agree with that. Tackling them small deals with any future problems with as small a cut/wound as possible. .
