Keizer's Fungi Q & A.

[sloth]

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a species name always is, that the "new" name was given to the species long before the "older" and because of that no longer valid species name.

 

Thank you but if for example, lipsiense and applanatum are the same fungi, what was wrong with applanatum? Who decided on the change, and in light of what new info?

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.

Oh, I misread and didn't realise lipsiense was the original name. So why was it changed to applanatum, why not leave it as it was all along!? Am I being awkward? it just seems odd to me to change, then change back? Sorry if I am just being dumb!

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.

What a state of affairs! If it where up to me, a name would be a name, full stop thanks!

found this today on an acer platanoides, i think its xylaria hypoxylon but would it grow this high up and is it the right time of year, and what would it be doing to the tree if it is?

Rob,

You're right on this , it's Xylaria hypoxylon, a "year around" fruiting ascomycete, which in its imperfect phase is producing whitish conidiospores. Xylaria's normally live on/of dead wood or other substrates, in which the mycelium causes a superficial soft rot, on or partially immersed in the forest floor. In this case you have documented an exception, I have only once seen before by X. polymorpha on a wound on the trunk of a beech at two meters height.

Not read all the post yet and q & a's but what a great resource..! Thanks for giving the time to provide answers.

Gerrit my fungoid friend, could you please shine some light on this group for us.

 

A colleague came across them on an Oak stump in Windsor a number of years ago and believes them to be a Cantharellus species ?

 

Over to you
