This page will cover some of the basics for the genus Strobilomyces, within the family Boletaceae. This genus is known for its black scales that cover the cap and most of the stipe. The name comes from the Greek root 'strobilos', meaning pine-cone, and 'myces' being mushroom/fungus. You may notice that the exceptionally large scales look almost like a young pine-cone in texture.
Strobilomyces are a unique bolete in that they are almost only black and white in color and have a remarkable texture from their large 'woolly' scales that is easily spotted from far away.
The coarsely scaled cap is almost always white or light grey, but sometimes the scales are large enough to obscure the cap surface. This older specimen also dried out and darkened with age.
The stipe will have the same wooly scales and often a ring, or ring zone that the hanging sterile tissue around the margin (edge of cap) were connected to. The stipe is approximately the same width from top to bottom. You may also see some reticulation at the apex (top) of the stipe.
When sliced, the context and inside of the non-hollow stipe will be white but may slowly bruise into a dark red color.
Make sure you cook these thoroughly.
