Observation 4759: Suillus pseudobrevipes A.H. Sm. & Thiers
When: 2007-11-05
No herbarium specimen

Notes: Having trouble with these. They have some characteristics of S. caerulescens but the caps are darker and seem more viscid. The veil is very minimal. The pores are fairly small and dirty goldish with no discolorations noted on any part of the specimen. The spores were reddish brown, medium sized and somewhat sub-oblong.
They were growing near pine and maybe tanoak but not Douglas-Fir.

S. pseudobrevipes probably right.

Initially I had rejected S. pseudobrevipes because of the very weak annulus and the references(Thiers and Arora) stated brown spores. These definitely had a red element to them. Now I see Bessette etal in North American Boletes describes them as cinnamon-buff and oblong in shape. That matches much better with my specimens. Also the annulus quantity seems less important in re-reading the descriptions. However, how does Bessette come up with variations on a species described by Thiers?

The annulus, tight pores and lack of strong glandular dots are the hallmarks of this one. Check out Suillus pseudobrevipes.
