no, too fat by a long stretch, dead mans fingers polymorphas:001_cool:

 

How can you possibly make that assumption without knowing the scale of the subject ???

 

 

These were very small, were talking milimeters.

sorry but as Gerrit says, it is limited to sycamore, which apart from fagus is the most common ground for polymorpha in the u.k too IME.

 

the two common names give away some morphological clues, the dead mans fingers, and the fingers of his unfortunate moll, the mans fingers being more robust than the unfortunate and delicate ladies (molls fingers) 2nd image.

Just as the Latin names do, polymorpha meaning with (lots of) different shapes or forms and longipes meaning with an elongated foot or base.

Are we saying his pictures & description of hosting on syc & "other" broadleaef trees, as being completely wrong ???

you know what I think, even with his book yours are polymorpha, and you can bank that 100% and I dont do 100% often these days as you know!

Not convinced at all.

Your going to tell me you're right & all these people are wrong ?

Just as is the case with the 100 % certain identification of Ganoderma lipsiense and G. australe, which only is valid after checking the spore size, the 100 % identification of either Xylaria longipes or X. polymorpha can only be done by using the microscope and not by evaluating it's macroscopical morphology.

So yes, X. longipes is sometimes found on other substrates then Acer, but how many of these identifications are valid, because they have been checked microscopically and how many are false, because the observer thought, he could distinguish X. longipes from X. polymorpha by its morphological characteristics ? For example : I documented X. polymorpha 7 times from Acer, but only after I checked the material microscopically, because from its macroscopical properties I could not determine whether it was X. longipes or X. polymorpha.

And the same goes for many other species with look-a-likes, which only can be identified by their microscopical features. I once checked 50 herbarium collections of K. deusta, with the result, that 8 of them were of 3 other (saprotrophic) species. So then one starts wondering what happened to the trees they were collected from.

[David Humphries]

Thus mine could be longipes or polymorpha, and should be left as undetermined until checked (unlikely)

Food for another thread perhaps.

 

Thanks for the info & thoughts Gerrit

I do believe one of your frequently used sayings is quite apt here...........pot/kettle
