Observation 83899: Suillus fuscotomentosus Thiers & A.H. Sm.

When: 2011-12-01

Collection location: near Georgetown, El Dorado Co., California, USA [Click for map]

Who: fewteeth

No specimen available

Under ponderosa in clumps, sometimes solitary, but mostly with near neighbors, flesh is yellow; with tubes removed and cap decorticated, very tasty. We have eaten a number of these without ill effect, but I would really like to know what they are. Can’t find them in any of my books.


reticulated stipe is common
yellow flesh

Very typical S. fuscotomentosus

This is one of the firmer members of the slippery jacks. Has fooled many people for being a Boletus, but it is not.

The stalk is definitely reticulate, though how you would know this from the pictures is beyond me. Better pictures next time. Flesh is reminiscent of the European B. Edulus which we collected on Mt Etna many times, firm and not the least marshmallowy, as one would expect from a Bolete. Most Suillus have very soft flesh. I stick with Boletus.

I looked up your reference book and they do not list Suillus fuscotomentosus. A good rule of thumb is if the stipe has a reticulate netting it is a Bolete and if it has dots it is a Suillus. A great book is Mushroom Demystified by David Arora, a local Californian author.

It is a good idea

to not eat anything until it has been properly identified. It could kill you and whoever else is joining you for dinner, or cause severe vomiting, or it might just make a fine meal. If you don’t know, don’t risk it.

Flesh texture?

Is the flesh soft and squishy, or firm? Are the caps always dry? It could be a bolete or a suillus.
How about Suillus fuscotomentosus?
