Tobias, Some macrofungi from Sweden.

Does this Californian Jurupa Oak qualify as a veteran tree ?
-
Trees "eat" pollution better than expected.

Hamadryads diary- a new chapter
Fungus replied to Tony Croft aka hamadryad's topic in Fungi Pictures
Not an uncommon combination in The Netherlands either and sometimes even on the same trunk, leaving behind a black demarcation line where the two mycelia and types of rot meet and compete. IME Piptoporus is the faster (cellulose) decomposer causing the tree sooner to fall. -
, atypical and with big FB's because of the richness of the substrate.

Tis the season to see Fungi, fa la la la la....
Fungus replied to David Humphries's topic in Fungi Pictures
In New Zealand it's Pycnoporus coccineus. And did the other bracket fungus have fine whitish to greyish pores ? If so, it might be Trametes hirsuta. -
Dave, Me too, so I already challenged this IMO unlikely hypothesis.
-
Far too big umbrella far such a small toad .
-
Pat (jammydodger) asked what chemical or compound triggers advantagous buds to develop. The plant hormones mainly responsible for directing the growth of trees are the auxins.

Sure : © Tony Sorensen (2011) .

Tony, ... if so, wouldn't this mean, that in future all climbers should be banned from trees and only platforms and high altitude camera's should be allowed ??? Don't tell this to David .

inonotus hispidus decay Sratergey on Quercus cerris
Fungus replied to Bart's topic in Tree health care
Just as the also biotrophic parasitic Meripilus giganteus : soft rot = sap wood (parasitic), white rot = dead wood (saprotrophic). -
Tobias, Some pictures of macrofungi from Sweden : 1. Clavariadelphus sachalinensis. 2. Lactarius scrobiculatus. 3. Lactarius zonarioides. 4. Phaeolepiota aurea. 5. Phellinus populicola. 6. Cortinarius (= Rozites) caperatus. 7. Thelephora caryophylla. 8. Amanita virosa.
-
In Dutch, it's called the Gaudy or Show off stiped bolete.
-
Yes, I found it twice on Acer in The Netherlands and both times fruiting from/inside a large wound/cavity.
-
No, not to the tree, but more competative than A. mellea because of its better resistance to resins (coniferous trees) and acids (Quercus robur, Castanea sativa).
-
No, on spruce.
-
1. Acer is not capable of compartmentalisation of the from the central wood column through the radial rays outward development of the soft rotting mycelium of K. deusta. 2. No, the difference is, that it would have died without becoming unstable at the same time.

Clearfell vs Selective cutting -myco impact?
Fungus replied to Xerxses's topic in Forestry and Woodland management
Tobias, Illegal ? I've seen several plots of these selective cutting trials in spruce forests in the Finnskoga area close to Höljes, where one healthy and vital tree out of 15 spruces was left behind around which the young spruces were replanted. The newly planted areas - and my wife and I once - were then "sprinkled" with nutrients and lime by helicopter. This method is preferred over clearfell because of better drought resistance, lower erosion risks, keeping the greater part of the soil food web intact and the presence of spores and hyphae/mycelia of ectomycorrhizal macrofungi attached to the roots of the left behind tree, that easily and rapidly colonize the roots of the planted trees through root-root contact, protecting the roots against pathogens in an early stage of their life cycle. -
It's Armillaria ostoyae producing the black oozing.
-
Dave, 1. On the basis of what research data do you assume that this actually is the case ? 2. In different situations (city versus rural) all things are not equal, because of the differences in density of trees and the associated infection chance by short or long distance travelling spores from the infected sources, air and water pollution, the lack of or poor association with mycorrhizal fungi by city trees altering the defensive system of the roots and the tree as a whole, etc.
-
I would sooner expect this to be caused by the intense simultaneous white rot of the mycelium of Phellinus tuberculosus.
-
Tom, Yes, it (probably) would, just as layers of woodchips do.
-
Or Oxyporus populinus.
-
So here are some photo's of rare macrofungi, I found in the Eifel region in the period 2007-2010 : 1. Amanita submembranacea. 2. Boletus junquilleus. 3. Boletus calopus. 4. Cantharellus friesii. 5. Hygrophorus pustulatus. 6. Leccinum griseum. 7. Lepiota clypeolaria. 8. Porphyrellus porphyrosporus. 9. Pycnoporellus fulgens. 10. Strobilomyces strobilaceus.
