Gyrocephalus rufus (Jacq.) Bref. This species is sometimes very 

 abundant. It grows on the ground, generally from buried wood, or 

 from dead roots. It is erect, stout at the base, and the upper end flat- 

 tened and thinner. It is more or less spatulate, the upper side some- 

 what concave, and the lower somewhat convex. In some plants 

 the pileus is more regular and there is then a tendency to the funnel 

 form. It is reddish, or reddish yellow in color, smooth, clammy, 

 watery, and quite gelatinous. When dry it is very hard. Figure
