Observation 119220: Butyriboletus persolidus D.Arora & J.L. Frank
When: 2012-12-06
No herbarium specimen
0 Sequences

Found 2 of these large Boletus at the base of a tan oak cluster. Caps are 8" and 9" across. each weighing about 2.6lbs each. The pores bruised blue instantly. these were a tad water logged as it had been raining the day prior.
Mild ‘mushroom’ scent and flavor.


bad spore print
I did not eat them as I am very new to mushrooms. I wanted to further dissect them to take a look inside.
reticulate where stipe and cap meet.

nice attention to detail, this is a thorough observation, welcome to mushroom observer! These sure do appear to be butter boletes, so if you still have them around you could throw them into a tasty meal, i usually find them quite maggot-ridden, especially when they are that size! The santa cruz mountains are popping off right now, happy hunting!!!
