Tis the season to see Fungi, fa la la la la....
David Humphries replied to David Humphries's topic in Fungi Pictures
Fine collection of images Rupert. Likewise, it's a good way to put a collection of fungal highlights together https://www.instagram.com/mycoappman/ -
You're confusing me with a cast member from the Detectorists

Ha, actually looks like that. No, common or garden green bottle glass.
-
Interesting find under a small girdling root on a maple.

Anamorph or teleomorph ?

Happens all the time, that one catches me out constantly

Just a heads up to a new book that's just been published by Andy Overall Fungi, Mushrooms & Toadstools of parks, gardens, heaths & woodlands http://www.fungitobewith.org/fungi-book/ Andy's a field mycologist but has published articles on tree specific fungi among many other things The new photographic guide is not specifically aimed at trees and fungi (more generalist) but you can find most if not all the usual associated species. We've been helping Andy for a few years with various bits and pieces and in return he's done a lot of our microscopy and general identification work as well as our survey work. A very symbiotic relationship that's been fruitful in developing my own understanding of the kingdom of fungi. I can highly recommend this resource.

Yep, that's an example of felling for highway safety .

The highest % of imported sawn softwood into the UK comes from Sweden, Finland and Estonia and the majority of sawn hardwood comes in from France, Germany and Latvia (FC stats) To my knowledge, the U.K. Is not one of Polands export destinations for timber. we do get lots of their apples though.

From talking to friends who care, It's quite apparant that due to changes in legislation there has been a significant increase in the number of trees being felled across Poland, both in urban areas and nature conservation sites like Bialowieza. There is a concerted effort by activists and citizens to lobby against the removal of so many trees but these passionate groups need help both nationally and internationally in raising awareness. If you have the time and you're interested please take a look at the crowd funding website below for more information on the campaign https://www.indiegogo.com/projects/save-poland-s-trees-nature#/ Thanks for reading

Willow looks like it would go on working as a coppice if put on to a 5 - 10 year cycle. The sycamores look to have good potential for bats, I'd be looking to pollard them.
-
The galls of Dryomyia lichtenseinii all over the leaves of this Holm oak in the Basque region of Spain Each gall has a larva of a mosquito from the Cecidomyiidae family.
-
Perhaps, it's definately a possibility, but I haven't seen the fruitbodies of the Armllaria so not able to identify which species, it may just aswell be one of the more benign species like gallica/bulbosa taking advantage of dysfunctional wood volumes.
-
Roadside beech which has had the fruiting of the giant polypore (Meripilus giganteus) for at least the last 5 years. Not one of my trees but I spoke with the owner and the neighboring Tree Officer about my concerns over the last couple of years, particularly as the canopy vigour was starting to decline. The owner eventually got a team in to dismantle it. The decay still had a while to go but not one to take chances on. Interesting to note that the rhizomorphs of Armillaria are also associated.
-
Fine example of aerial rooting on this oak pollard in the Sierra Andia region of the Basque. Can trace the 'roots' from the inside of an old occluding wound at the end of a hollow scaffold, right down to the soil.
-
Not on these ones, they only hold the trees unique identifying number.
-
Is the bracket soft (ie; an annual fruit body) or hard as in perennial?
-
I talked to Ashtead about our trial in about 2008 but I don't think that they or Epping went ahead with it.
-
Blimey it was 10 years ago, but I seem to recall that the chips were about £3.50 each and the scanner about £400. Considerably more than conventional metal tags, but may have the potential to last longer and not be seen.

Trasmochos (pollards) of the Basque
David Humphries commented on David Humphries's blog entry in David Humphries
It's a hard slog Josh, but someone had to step up and volunteer Higher vitality trees (ones with lots of dense photosynthetic material) which are subjected to smaller sized cuts, (because the regrowth is younger and less size in diameter) can occlude and compartmentalise the wounds more effectively than lower vitality trees with large wounds. This will hinder fungal colonising species with wound entrance strategies (not including the dormant endophytic species though) The older lapsed pollards (with large diameter wood volume and tall old-growth poles) can end up having large tear outs which open large wounds which get colonised more readily. -
Relatively recent Fomes fomentarius snap out, interesting to ponder on the profusion of epicormic growth below the fracture point. (in comparison to the adjacent trees without the brackets and less epicormic growth) Did the tree sense it coming and its pollarded itself !?!

looks like resinaceum

Kretzschmaria deusta and Pleurotus ostreatus

Kretzschmaria deusta and Pleurotus ostreatus
David Humphries replied to MarkJR's topic in Fungi Pictures
A. tabescens for reference Rarely noted (never seen it personally) on the stem of trees unlike some of the other Armillaria species.
-
Just back from a return trip to the Basque region of Spain, and saw a few bits and pieces whilst there but it has been dry for most of the Autumn so not a good showing for mycorrhizal species. Fomitopsis pinicola on a douglas fir stump Fomes fomentarius on just about every dysfunctional beech tree Ganoderma australe on beech Ganoderma pfeifferi on beech Cyathus spp Hydenum repandum Phellinus spp on oak (possibly P. robustus)
