The genus Gyrocephalus differs from the other Tremellineae in having the fruiting surface on the lower side of the fruit body, while the upper side is sterile.
Gyrocephalus rufus. Reddish or reddish yellow (natural size).
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 flattened and thinner. It is more or less spatulate, the upper side somewhat 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 208 represents the form of the plant well, from plants collected at Ithaca. The plant is quite common in the damp glens and woods at Ithaca during the autumn.
