Rob, May still be wrong ? The Armillaria I told Tony about is an endemic American species .
-
Both, but can you show me pictures of authenticated Amanita fulva with the A. ceciliae characteristics as described by me and depicted in your photo's ? And did you microscopically identify (differing spore sizes) any of your Amanita fulva specimen including the one in your last pictures ?
-
They're at one end of the spectrum, you can find lots of examples of the other end of the spectrum, that resemble your and Andrew's pictures under Amanita ceciliae.
-
What more needs to be said : false claims and plagiarism on top of it ?
-
David, See : pictures 10/11, your own pictures and Amanita ceciliae.
-
Andrew & David, Because of the size, the lack of a volva and the horizontal flocculose whitish zones on the stipe, I think this is Amanita ceciliae too. This specimen, however, has lost its scales on top of the cap.
-
I disagree, no distinct volva (because of easily falling apart of round cells), cap ochrous brown to dark grey-brown, with striate margin and large patches, stipe with 2-3 ring-like zones at the bulbous base : Amanita ceciliae (= A. inaurata).

Rowen, 1/4. Hypholoma fasciculare. 2. Beech with ??? 3. On dead wood ? If so : Lycoperdon pyriforme. -

Rowen, 1. Leccinum species, with Betula, Quercus, Populus or Carpinus ? 2. Amanita fulva. 3. Hypholoma fasciculare. 4. Hymenochaete rubiginosa. -

Rowen, 1. Russula species, probably R. ochroleuca. 2. Russula nigricans. 3. Coprinus picaceus. 4. Amanita muscaria. -------------------- 5. Russula species. 6. Daedaleopsis confragosa. 7. Laccaria amethystina. 8. Russula species, maybe R. fragilis. -
Terry, Correct .

Rob, I have a Bresser USB microscope digital type E102012 from Meade Instruments (Germany) of 49 Euro with 20, 80 and 350 x magnification and these are some of the 20 x pictures, I took with it. 1. Leaf of Wisteria with natural decoloration. 2. Mite or tick on pores of Coriolopsis trogii. 3. Spines of Hydnellum spongiosipes with sand grains on top. 4. Rust on willow leaf. 5. Myxomycete Physarum cinereum. ---

Rob, See the Meripilus thread.
-
Rob, There is only one parasitic Armillaria species, of which is documented, that it mimics feromones (not enzymes) of ectomycorrhizal macrofungi, and that's a non-European, i.a. an American species.
-
Rob, Yes, I have one record of M. giganteus on Ginkgo biloba from The Netherlands.
-
Last two pictures : Amanita ceciliae/inaurata ? And for an answer to your question, see the synopsis of my article in Der Tintling.
-
1. You mean, one has to understand the biochemical and molecular triggers, that regulate the balanced biotrophic parasitic relationships of these fungi with their tree partners ? 2. Sure, immediately after your first time registration on this forum reactivating a thread after a period of silence of almost a year is only out of merely taking an interest in an open discussion and totally lacking commercial motives :lol: ? 3. So to demonstrate, that you don't need the advertising space, you repeat your website address for the third time, to which you drew attention by invading this thread in the first place ?
-
And definately no Phellinus igniarius or Bjerkandera adusta in these images too.
-
Nick, Yes, they are : Ganoderma australe used to be named G. adspersum and Ganoderma lipsiense used to be named G. applanatum.
-
Bjerkandera adusta or B. fumosa. Oxyporus populinus looks like this, see photo. ---
-
See the Meripilus thread.
-
... some of them are extremely bitter or lethally poisonous.
-
Ganoderma species don't cause simultaneous white rot (or brown rot), but white rot with selective delignification.
-
It may be counter intuitive, but research on the effects of air pollution on urban and roadside trees has shown, that these trees function as dust filters "storing" particulates, pollen and spores on their foliage until the rain washes it down and transports it to the sewer system and that's why urban trees are more than just the lungs (oxygen) of our cities .
-
I share this observation. In a Dutch woodland dominated by birches on poor sandy soil I've been monitoring, a month ago I found hundreds of Amanita fulva, which also were very variable in size. And there were a lot of Amanita muscaria, Russula betularum, R. claroflava and R. aeruginea present too.
