Observation 94309: Boletus edulis var. grandedulis Arora & Simonini

When: 2012-05-09

Collection location: University of Washington, Seattle, Washington, USA [Click for map]

Who: BlueCanoe

No specimen available

Growing directly beneath Pinus rigida with Cedrus deodara nearby; both tree species are non-native ornamentals planted in a landscaped area.

Update: on May 24 (15 days after first observation), found a second specimen near the same individual pine tree. No significant precip in Seattle from May 5 to 20, showers and rain from May 20 to 24. This second specimen was partially buried by pine duff and measured 14 cm high, 15 cm wide, and weighed 595 grams. No bluing observed. A friend told me that fresh porcini are going for $50/lb at Pike Place Market right now, making this mushroom worth a bit over $65 at that rate!

Recognized by sight: not certain this is the native Boletus edulis var. grandedulis only because it is in an urban environment associated with planted, non-native trees; Boletus rex-veris also a possibility

I brought this one home for the table. There may be more in the future, but I only saw one. This was near the Waterfront Activities Center.

Despite the weird time of year, I think this is more likely B. edulis than B. rex-veris. Brown & cream color on this specimen, versus more reddish-brown and yellow/tan on B. rex-veris. And I haven’t heard of B. rex-veris occurring in the lowlands of western Washington. Although anything’s possible, I suppose.

Mind divulging the location?

I promise not to eat them, only shoot them!
