Observation 86102: Suillus sibiricus (Singer) Singer
When: 2011-09-03
No herbarium specimen
0 Sequences

Suillus sibiricus, the Siberian slippery jack, was found on a hike up to Mt. Wrightson in Arizona. Among the ranks of the first few fungi that I’ve found and documented, my notes were very simple and the images don’t focus much on the mushroom’s features. (Don’t worry, I’ve made progress.)


Cap: viscid and sticky, with orange and yellow tints. This one was 5.5 cm across.

Stalk: yellow and non-smooth.

Pores: fairly large.

Substrate: this was found a couple of centimeters near a tree, growing from leaf litter. The tree was most likely a conifer, a white pine or limber pine typial of S. sibiricus growth in the Southwest.

Spores are shown in one image along with the flesh, and then the flesh is shown again after it naturally dried.
