History, Use, Propagation, Culture, 
2396. Cryptomyces. Upon this curious addition to the British Flora, Dr. Greville has the following remarks. 
" This very curious plant, I have little hesitation in placing as a new genus among the true Fungi. It is 
difficult to say, with what it has nearest affinity. In general habit, it might be supposed to resemble some 
species of Thelephora, but there the comparison stops. Our plant, besides being produced under the epidermis, 
seems to belong to a more perfect group, when its structure is examined. The hymenium is a quite distinct 
substance from that of the receptacle. The fructification is fully and beautifully developed, a good deal similar to 
that of the Helvellee. The receptacle is carnose and white ; and the whole exhales a very strong odor, precisely 
like what is universally known under the name of a fungus-like smell. Till the plant is perfected, it remains 
concealed beneath the epidermis ; and on this account, I have named the genus Cryptomyces. The epidermis, 
in fact, scarcely seems to crack by the swelling of the fungus, more than by the natural consequence of being 
killed by its separation from the subjacent bark. A cluster of willows, which was attacked in the beginning of 
the season by this plant, has been nearly destroyed by it; and, from the rapidity of its progress, I have no 
doubt that a whole plantation might, in the course of a couple of seasons, be rendered good for nothing. At 
a little distance, the affected branches look as if they were dry, scorched, and rotten." 
2397. Tremella. Large or middle-sized fungi, rooting at the base, which is considerably contracted between 
the bark and the wood of trees. Dillenius named the genus on account of its soft, tenacious, tremulous sub- 
stance, but his name was applied in a far more extensive sense than at present. The section called Phyllopta 
is an aberrant form of the genus, and should perhaps be separated. 
2398. Exidia. From £|£/a<./, to proceed from a thing ; with reference to the manner in which the sporidia 
exude as it were from their receptacle. This genus differs from Tremella, to which it is nearest, in its hori- 
zontal Peziza-Uke receptacle ; in its hymenium being superior, the lower surface being dissimilar and either
