Oss. These plants when young lie flat and are closely attach. 
ed to the substance on which they grow, the upper surface being 
smooth, but the under surface shaggy with hairs which serve the 
purpose of radical fibres. After some time the attachment 
formed by these fibres loosens, and the plant turns up more or 
less, but remains still attached in some one part, either central 
or lateral. The smooth upper side is now become the under one ; 
and from this the seeds are discharged. ‘The fibrous surface, 
now uppermost, continues shaggy or woolly, often becomes 
streaked or zoned in concentric stripes, and frequently assumes a 
variety of colours. A process similar to this takes place in 
some of the stemless Agarics and Boleti, See Ag, quercinus 
and Bol. versicolor. ; «Se ae

Grows very much tiled. The zones more apparent on the 
upper than on the under surface, about 1 or 13 inch wide, and 
half as much in breadth. M. Bulliard observes that if a por- 
tion of the under side be dissected from the upper coat, it ap- 
pears perforated in the microscope.
