Observation 191950: Butyriboletus persolidus D.Arora & J.L. Frank
When: 2014-12-05
No herbarium specimen

Notes: Found in leaf litter near base of what appeared to be a small dead/dying manzanita shrub, otherwise in an area of predominantly live oaks with some gray pine interspersed.

Notably bulbous stipe (~7 cm long, 7 cm diameter) nearly as wide as cap (9 cm diameter). Cap surface moist, tan with brown patches that tended to be slimy (note: it has rained recently). Underside of cap pale yellow, dense, firm, assumed to be tubular (no obvious gills). Top half of stipe yellow, similar to cap underside; lower half that would have been below soil level more tan-colored.

A large, roughly spherical protuberance (~2.5 cm diameter) off base of stipe on one side, that itself appears to have several smaller protuberances off of it. Possibly a separate fruiting body forming?

Faint localized blueing of presumed tubes with very firm pressure or slicing, but not striking.

A dense, ~10-oz specimen.

Taste raw cap: mild, not at all bitter.

Note: I ate this mushroom (cooked, sauteed in butter) gradually over several days and noticed no ill effects. Great texture, tasty!

Lab photo is best in this case, showing yellow underside of cap, yellowish stipe transitioning to tan, and apparent
protuberances at base.

In situ (field) photo without flash is closer to actual predominantly tan color of cap with brownish patches. Leaf litter has been dug away to reveal protruberance below stipe

Cross-section reveals reddish tinge toward base of stipe. Specimen was notable for its firmness in slicing, akin to cutting a raw potato

After sauteing in butter…no remarkable color changes.
