CRYPTOGAMIA, ALGE. Byssus. (1) Thread-like. «4143 
upon an old elm chair which received the drippings from a 
water cistern; and J am indebted to the kind attentions of her 
Ladyship for fine specimens in the highest state of perfection. 
The Byssus barbata when fully grown resembles this species 
in colour and in height, but that is marked by transverse lines 
shewing the growth of each year, similar to what we see in 
the tubes of the perennial Boleti, and the stems split at the 
ends into a number of capillary fibres. 
Dr. Smith in E, bot. is of opinion that this plant is the 
same as B. barbata,  —s_- a 
Moist rotting wood, and tubs used to catch rain water. 
pepe eS A. July—Aug. 
B. Threads tawny, nearly upright, and of the same barba’ta, 
length ; the ends branched.

_ _ When young yellow, short, densely compacted, spreading 
wide, resembling a fleece of wool. When older it attains the 
height of 2 inches, grows upright, but closely crowded toge- 
ther, the top of each filament dividing into numerous very 
fine fibres so as to appear downy. It is then tawny or saffton 
coloured. The growth of each year is marked by a transverse 
line. Diuw. coe ; 
Rotten wood and rotten trunks of trees. A. Jan.—Dec.

_ Substance tender, woolly, closely pressed to the surface on => 
which it grows; white, or livid, or yellowish. From a broad- 
ish woolly and mucilaginous base arise many slender branches, © 
spreading more in width than in height; elegantly divided and 
subdivided, the extremities ending in capillary fibres or an ex- 
panded surface. Dit. 
On rotten leaves, rotten wood, and half rotten leather.

* Micheli, cited by Linnzeus, and Hudson; and Dillenius referred to 
by Hudson, describe them as xo? draxched. Hudson gives two synonyms 
from Ray. The first appears to be the plant of Mich. and Dill. the se- 
cond, which is described as ramrosissimus seems to be what fell under Mr. 
Hudson’s immediate inspection.. Mr. Woopwaan. = :
