Observation 69288: Suillus pseudobrevipes A.H. Sm. & Thiers

I have been collecting this species off and on for about 10 years in various locations in the eastern Cascade Mts. I am not convinced this is S. pseudobrevipes but is as close as I have been able to find. The differences I have noticed from S. pseudobrevipes are: (1) fruits during morel season (May and early June)not summer (July and Aug., (2) Often a bright yellow when fresh not the honey yellow described by Smith and Thiers, (3) Most often found without any veil remnants on the stipe not as described by Thiers with a distinct annulus. The collection that is pictured shows more remants than I have seen before.

Habitat is mixed conifers but usually with some young pines (10-15 years) nearby.

Blue Canoe,
The edge of the cap of the suillus you observed appears to be more firbrillose than I have seen on any of my collections. Veil remnants or overal cap condition?

Answers some of my questions!

Thanks Noah. I had considered S.vocanalis but discarded because it totally lacked annulus. If they are the same species then it seems that the species must vary a lot depending on enviormental conditions. I feel better about calling it S. pseudobrevipes now. Still have questions about the season and one that I didn’t mention before; the frequent occurrance of multiple fruiting bodies joined at the base.

“Suillus volcanalis is probably not a real species

We’ve sequenced two Thiers collections of volcanalis, including the type, and its identical to S. pseudobrevipes"
