Habitat: coastal oak woodland; dripline of Quercus agrifolia

Substrate: oak duff

Cap: 5-3/4"w/14.6 cm w; reddish-brown; wavy on the edges; almost flat; subviscid when wet; adhering debris

Pores/Gills: orange-red, smooth, slowly bruised to blue, easily separated from cap

Stalk: 5-1/2"/14 cm h x 3"/7.6 cm w; nonreticulate; bulbous toward the base; golden yellow bruising very blue quickly. The next day the blue color had disappeared, and the stalk was medium golden yellow.

Additional Notes: These unusually large (compared to the range in sizes I read about in several descriptions) specimens of Suillellus amygdalinus were formerly known as Boletus amygdalinus. They are usually found under Quercus agrifolia (Coast Live Oak), Arbutus menziesii (Madrone), and Arctostaphylos (Manzanita).
