Rob, My mistake, I thought ermine moth meant leaf mining moth, so : yes, the Ermine moth Hypenomeuta padellus is the species specializing in completely defoliating Prunus species including P. padus, and Lyonetia prunifolia is a leaf mining moth living on/in the leaves of Prunus species without defoliating the tree.
-
What tree species ? Beech ? If so, Ischnoderma resinosum ?
-
Matt, With such an impressive number of devil's eggs, there must have been lots of witches around at dawn, "creating" new offspring with the sperm of the devil .
-
Yes he was, just as his wife Dien, who was an expert on Pholiota and inspired me to "photo collect" and document all species, she described in her book. Frans taught me never to look for the obvious, but always to expect the exception with fungi.
-
Didn't you warn Spidy, that he might be in danger of falling on the ground together with the old annual bracket of Grand Master Pipto, because of the extra weight he put on it ?
-
Matt, What's this with you and the "impudent phallus" : you took them (as an aphrodisiac) ?
-
Rob, Hyponomeuta padellus is not an ermine moth, in The Netherlands, the ermine moth living on Prunus padus (and P. spinosa) is Lyonetia prunifolliela.
-
Because P. pygmaea is an often overlooked look-a-like, which sometimes "hides" in clusters of C. disseminatus. Once I started checking for P. pygmaea, I found this (IMO not so) "very rare" species three times.
-
I don't want to spoil the fun, but as my old mycology professor Frans Tjallingii used to say : "Never call all "individuals" of a cluster of small ink caps Coprinus disseminatus, if you have not first checked whether there are no Psathyrella pygmaea among them ."

Among taxonomists you have lumpers and splitters and depending on who's in "charge" at a specific time, species names change to former names or are given "new" names. Besides, if one really wants to "score", one must try to name complete genera after oneself, like Kuehner did, in changing Pholiota mutabilis to Kuehneromyces mutabilis (= Kuehner's mushroom, which is under mutation of names), thus provoking taxonomists to rename it again, which they - of course - did.
-
Definitely the plasmodium of a myxomycete or slime mould such as Badhamia utricularis or a Trichia species .
-
You wish, the trees don't .

After first finding it on Acer in Poland, last week in Austria alongside a river passing Aurach (near Kitzbühel), I again documented Fomitopsis pinicola on six old Acer's, some still living, some dead, standing within one kilometre on the riverside. I was surprised by the differences in colours of the brackets, ranging from orange red to pale brown and even entirely grey. ---

As I said before, G. lipsiense was an older and thus originally valid name, so they had to change it back from G. applanatum to G. lipsiense. It is only a matter of taxonomy rules mycologists have agreed on.
-
Alongside the rivers in eastern Austria, all Prunus were completely defoliated by the caterpillars of the moth Hyponomeuta padellus. The branches and trunks of the trees were covered with shiny silvery spinnings, which even "bridged" the spaces between branches and/or the trunk. ---
-
In Austria (Kitzbühel), last week I found several Aesculus with Bleeding Canker caused by Pseudomonas syringae. The photo's are from a horse chestnut, which was severely damaged by the infection at one side of the trunk, but still full in foliage. ---

Rob, In The Netherlands, after Quercus, Robinia is the second tree species most often colonized by L. sulphureus. In Robinia, the mycelium completely brown rots the central wood column, after which the tree holds itself up by strengthening the connecting zones between the outer wood columns, which in their turn each connect a major root to a major branch, creating a "bouquet" of several single one root-one branch "trees" with a hollow inside. Photo L. sulphureus on Robinia. ---

V.T.A symptoms "the chatty trees"
Fungus replied to Tony Croft aka hamadryad's topic in Tree health care
Two days ago in Germany, I spotted this Prunus avium with very obvious "compensatory" body language. ---
-
The only two recent name changes are Ganoderma lipsiense, was G. applanatum (applanatum = flattened) and G. australe (australe = from the south), was G. adspersum (adspersum = scattered). And the reason for changing a species name always is, that the "new" name was given to the species long before the "older" and because of that no longer valid species name.

Drew, A Peziza species from the Peziza cerea sensu lato (incl. P. varia) group, probably Peziza cerea s.s.

.
-
You can add Ulmus too.
-
In my database, I've once documented P. squamosus fruiting from a pruining wound on the trunk of a Carpinus. As far as the extent of the white rot could be evaluated without damaging the tree, it seemed comparable to what P. squamosus does to beech.
-
With only the bark as a reference, if you would have said it was Aesculus or Carpinus, I would have believed you too.

On Prunus ?
