surface layer, which is not strigose hairy. Stereum versicolor Swartz, 

 to which authors have referred this species, was collected in Jamaica 

 and has a smooth surface (Lloyd, Myc. Notes 33: 429. 1909). My 

 plants have been seen by Burt, who determines them as above.

Caps small, shelving from a more or less resupinate base, petal- 

 shaped or shell-shaped, often fused laterally, usually projecting 3-17 

 mm.; surface zoned, smooth and silky-shining except near the base 

 where it is covered with white, gray or tawny fibers, or the hairs 

 may occur on some of the zones more than half-way to the margin, 

 or very rarely all over; color when quite fresh and damp a light och- 

 raceous on margin, passing through ochraceous to reddish ochraceous 

 at base, when dry a deep chestnut brown with paler zones, or when 

 old. and weathered the color may fade to much lighter. Hymenium 

 smooth, strong, uniform ochraceous when fresh and damp, changing 

 to a creamy flesh color when dry. When on horizontal branches the 

 under side of the branch may be completely covered by the resupinate 

 part, which gives rise on the sides to a long fringe of the projecting 

 caps. On drying the plant contracts so much that the resupinate 

 portion is often split and torn. 



Spores (of No. 3863) faint smoky flesh-color in a good print, 

 smooth, rod-elliptic, 2-2.8 X 5-7^1. Hymenium (of No. 3802) about 

 35[JL thick. 



When damp the hymenium also is faintly zoned but when dry 

 it is not zoned. The dorsal surface is on the contrary more con- 

 spicuously zoned in the dry state. A very pretty little plant which 

 often occurs on small twigs and wings them on both sides if they 

 are horizontal, also appearing in large numbers on larger branches.
