Observation 145835: Gomphus clavatus (Pers.) Gray
When: 2013-09-15
No herbarium specimen

Notes: Initially thought these were small, fragile Gomphus clavatus. After seeing multiple other fruitings in small tight clusters and investigating in Mushrooms Demystified/Mushrooms of the pacific Northwest I am leaning more towards Polyozellus multiplex. Not positive. All specimens we handled and encountered had this white mold covering the lower portion of the fertile undersurface and inside of caps.

Not distinctly blue. Greyish in color with light purple tips. Underside deeply grey and veined- almost identical to the bottome image in Trudell’s book on pg. 47(minus the white mold).

Anyone encountered this with P. multiplex or Craterellus sp. before?

Elevation: 4,501ft.

Trees in canopy- Douglas fir(mostly old growth), Mountain Hemlock, Spruce and Ponderosa pine.

Temp: upper 60’s.

Will monitor these collection spots over the remainder of the season to positively confirm species.

was correct. The color is great for G. clavatus, but I’ve never seen that rosy violaceous color on P. multiplex. They are blue-black with a whitish coating of ripening spores. Also P. multiplex are almost always compound instead of single. Spore color is different if you could get a print.
