Plate XLV. Figure 324.—Polyporus Berkeleyi. Reduced. Natural size being 2½ feet across.

Polyporus giganteus. Fr.

The Giant Polyporus. Edible.

Giganteus is from gigas, a giant. The pileoli are very numerous, imbricated, fleshy, tough, somewhat coriaceous, flaccid, somewhat zoned; color a grayish-brown in young specimens, the deep cream pore surfaces tipping the pileoli, rendering it a very attractive plant; this cream-color is quickly changed to black or deep-brown by touching it.

The pores are minute, shallow, round, pallid, at length torn.

The stem is branched, connate from a common tuber.
