Chestnut Mushroom Liquid Culture 10cc syringe

Gyroporus castaneus, or commonly the chestnut bolete, is a small, white-pored relation of the Boletus mushrooms. It has a brown cap, and is usually found with oak trees. It differs from the true boletes in that the spores are a pale straw colour.

The cap is from 3 to 10 cm in diameter, and pale to rusty brown in colour, which becomes darker with age. The stem is a similar colour, although it may be lighter at the apex. If the stem is cut vertically, it is usual to find several cavities of differing sizes inside. Both the cap and the stem have a tendency to crack or split in dry periods, or with age. The pores are small and white; they become dirtier with age, and are not attached to the stem. They darken slightly when pressed. The tubes are also whitish, and the spore print is pale yellow to straw. The flesh is firm, and does not change colour on cutting.
