Observation 163564: Pluteus tomentosulus Peck
When: 2007-08-01

Notes: While looking through some preserved materials I ran across these. They appear to be in good condition. Looks like the photo was taken indoors, so color may off. I recall these being almost pure white, because the closest thing I had found was P. semibulbosus, as portrayed by Phillips.

And nice work! A surprise to me that any useful molecular info was retrievable from this sample. It had been sitting inside a jar in my home for several years.

Hi Dave,

I got a sequence for this collection and molecularly it groups with all the other taxa in the Pluteus ephebeus complex.

Morphologically it fits the concept of Pluteus tomentosulus

The nrITS is identical with this collection from the West Coast:

Thanks again for documenting and sending the collection!

You’re welcome, Fredo.

And thank you for taking the time to study the specimen and post remarks.

could be Pluteus tomentosulus

Dave,

Your collection has arrived and I have scoped it this morning.

This is in the Pluteus ephebeus group, the pileipellis is a cutis, composed of parallel septated hyphae and the cystidia are not metuloid. This is a very diverse species complex, the “true” P. ephebeus is probably restricted to Europe but molecular data have uncovered at least 8 other species occurring in North and Central America.

Because of the size of the basidiocarps, the white colors, the microscopical characters and the geographical origin this collection could very well represent Pluteus tomentosulus.

I will try to obtain molecular data from this to see where it fits in the phylogenies

Thanks again for sending this over!

Okay Fredo.

I will have look at these if you send them over
