On damp decaying wood. Not uncommon, according to Dr. GreviUe. 

 —Fries informs us that the present plant, when young, has a peridium, 

 and that he has consequently referred it to the present Tribe. ^. setosa, 

 Grev. appears to me to possess quite a different structure, and to belong 

 to the genus Psilonia. 



Tribe 5. Perisporiace^. ('^rsfi, around, and tfTooo?, seed). 

 — Peridiu?n thin, submemhranaceous, bursting. Sporidia immersed 

 in pulp, free or included iji j^eridiola. 



101. Racodium. Pers. Racodium. 

 Peridium suhcorneous, rigid, scarcely bursting spontaneously, 

 suhgelatiuQus witliin. Sporidia arranged more or less in a 

 moniliform manner. Thallus abundant, between cottony and 

 spongy. — Name, ^«3ioj, li7if. 



1. R. celldre, Pers. (mouse-skin Byssus) ; thallus very thick 

 and abundant lax composed of septate flocci olive-black, peridia 

 globose seated upon the thallus and supported by simple flocci.

On casks, bottles, &c., in cellars, often hanging down a foot or more 

 from the roof, in almost every close cellar. — Persoon noticed the 

 appearance of granules upon the thallus and suspected that they were 

 the fructification. The name Antennaria, applied to this genus by 

 Fries, on account of the heterogeneous nature of Persoon's Racodium^ 

 is not admissible, being preoccupied for a genus separated from Gna- 

 phalium. This, as far as 1 know, is the only British species, for what is 

 marked in the Appin collection by Klotzsch Antennaria pinophila is 

 certainly something else, having distinct globose moniliform flocci, 

 throughout very different from those of the true plant, in which they 

 are rather torulose than moniliform. I have gathered the same pro- 

 .duction in Scotland on the bark of fir-trees, not on the small branches, 

 ?,nd believe it to be a species of Agardh's genus Chroolepus. 



102. Lasiobotrys. Kunze. Lasiobotrys. 

 Peridium carnoso-corneous, collapsing at the top, filled with 

 a ffranuloso-gelatinous mass contained in a solitary peridiolum. 

 Sporidia globose, filled with sporidiola. Thallus consisting of 

 short simple radiating fibres.— Name, J.umg, shaggy, and /3or^y,-,
