Polyporaceae 



Poiyporus. times with a short stem. Very occasionally a single pileus will protrude 

 from a tree like a giant yellow tongue shaded with reddish-orange. 

 Usually the pilei are in clusters united in a solid base, white-fleshed and 

 rich in color. I have seen clusters two feet across. On an old willow 

 at Mt. Gretna, a cluster 18 in. across afforded a dozen meals. When- 

 ever a meal was wanted a pound or two was broken off. It lasted until 

 January. If P. sulphureus is cooked properly it is a delicious fungus. 

 Cut fine, stew slowly and well, season, add butter, milk with a little 

 thickening. 



P. macula'tus Pk. having macuttz-spots. Pileus of a cheesy con- 

 sistence, broad, flattened, sometimes confluent, sessile or narrowed into 

 a short stem, slightly uneven, white or yellowish-white, marked with 

 darker zones and watery spots. Pores minute, subangular, short, 

 whitish, sometimes tinged with brown. Flesh white. 



Pileus 4-6 in. broad, 6-8 lines thick. 



Prostrate trunks of trees in woods. Worcester. July. 



In texture and shape this species is related to P. sulphureus, but the 

 pores are smaller than in that species. The plants are sometimes cespi- 

 tose, sometimes single. The spots in the dried specimens have a 

 smooth depressed appearance. Peck, 26th Rep. 



Angora, West Philadelphia. September, 1896. Mt. Gretna, Pa., 

 September, 1897-1898. On white oak trunks. Mcllvaine. 



Several specimens of different ages proved good eating. Like P. 

 sulphureus it must be well cooked. 



P. hetero'clitus Fr. Gr. one of two; Gr. , to lean. In many ces- 

 pitose layers, coriaceous. Pilei 2*2 in. broad, orange, sessile, ex- 

 panded on all sides from a radical tubercle, lobed, villous, zoneless. 

 Pores irregularly shaped and elongated, golden-yellow. Fries. 



On the ground under oak. Rare. 



The flat pilei extend horizontally from the tubercle. Irregular, ec- 

 centric. Stevenson.

Haddonfield, N. J., Hopkin's woods. June to July, 1890-1896. 

 Mcllvaine. 



Of all fungoid growth this is the most showy. Its clusters, often a 

 foot and a half in diameter and spread like mammoth dahlias, are gor-
