Observation 212850: Vanderbylia fraxinea (Bull.) D.A. Reid
When: 2015-08-07

Notes: This and another specimen (of different location) will be verified microscopically by Dr. Hans Adema. Based on macroscopic characteristics both are most likely P. fraxinea compared with Poroid Fungi of Europe (Ryvarden and Melo, 2013).

Thank you, Herbert! Your citation clears up this situation alot to me. I will use Vanderbylia in my own database (so here as well). But in the Dutch databases I have to use Perenniporia, since we have to conform to the forementioned Standardlist (Arnolds&Van den Berg, 2013).

Nice find.

I think it is the case that the various databases are simply not up to date here.

“Clade V includes Perenniporia fraxinea (Bull.) Ryvar-den, P. robiniophila (Murrill) Ryvarden and P. vicina (Lloyd) D.A. Reid, and species in this clade are character-ized by pileate basidiocarps, strongly dextrinoid skeletal hyphae, and amygdaliform, non-truncate and strongly dex-trinoid basidiospores. Reid (1973) established the genus Vanderbylia D.A. Reid to accommodate these species. But it was treated as a synonym of Perenniporia (Ryvarden1991). Our analysis inferred from ITS combined LSU sequences data showed that P. fraxinea, P. robiniophila and P. vicina formed a well resolved monophyletic clade with strong support (100 % BP, 1.00 BPP), and it is distant from Perenniporia s.s., and could be recognized as a separate genus of Vanderbylia (MycoBank: MB 18722.”

I will ask my friend to determine the age of the Populus stump it was growing on, so we can make an estimation of the age of the mushroom.
@Herbert Baker, as it comes to the name proposal Vanderbylia, I use the consensus of Index Fungorum and Ryvarden&Melo (2013), where it is still called Perenniporia. Also, here in the Netherlands we use a Standard List of Dutch Fungi (Arnolds&Van den Berg, 2013) to keep the names uniform for our species database. Every once in a while (8 to 10 years or so), a new one gets published. Again, Arnolds&Van den Berg (2013) still use Perenniporia.

It appears to have devoured the collector entirely —

Old enough to be my father.

It does look ancient…

My guess it had probably been growing long before you became a zygote, Dave! :D Sorry, couldn’t resist…

I wonder…

how long has this been growing?

Wow! What an amazing specimen. Great find.
