the antiseptic fluid, which, on being admitted, thoroughly pene- 

 trates the object to be preserved, impregnating even the marrow of 

 the bones. He adds, that the process is useful not only for the 

 prevention of putrefaction, but also in arresting its progress, the 

 gases generated during putrefaction being expelled from the re- 

 ceiver along with the air, and their place supplied by the antiseptic.

Read " On an edible Fungus from Tierra del Fuego, and an allied 

 Chilian species." By the Rev. M. J. Berkeley, M.A., F.L.S. 



Mr. Berkeley describes these two species as constituting a new 

 genus, which he characterizes as follows : — 



CYTTARIA. • 



.Receptacula carnoso-gelatinosa in stroma commune subglobosum, epider- 

 mide crassiuscula vestitum, aggregata ; basi stipitiformi granulata. 

 Cupula peripherica, primo clausa, gelatina distenta, demum epidermide 

 rupta aperta. Hymenium, margine excepto, separabile. Asci ampli, 

 demum libcri, paraphysibus immixtis. Velum persistens, demum 

 ruptum, margine plus minus reflexo. ijporjWia pallida. 



Genus Bulgarice affine, sad stromate pulvinato ex variis individuis com- 

 posite SphcBriam concentricam quodammodo referens, et hymenio sepa- 

 rabili valde diversum. Certe ad seriem Pezizarum pertinet, perithecio 

 spurio non obstante. Confer Sphceriam monocarpam, Sebum. adPezi- 

 zam rkizopodam a clar. Friesio ascriptam. Nomen dedi a xvrrx^os, 

 ob superficiem fungi alveolatam. 



1. C. Darwinii, vitelliua globoso-depressa, cupulis parvis ore irregular] de- 

 mum apertis. 



Hub. in Fagum betuloidem in Tierra del Fuego, Dec.-Jun. 



2. C. Berteroi, pallidior irregularis, basi subelongata, cupulis majoribus ; 

 , ore pentagono ; margine fisso reflexo. 



Hab. in Chili in Fagum obliquam, vere et a2state. 



The first species is noticed by Mr. Darwin (from whom Mr. 

 Berkeley obtained his specimens of both) at p. '298 of his ' Journal 

 and Remarks,' forming the third vol. of the ' Narrative of the 

 Voyages of the Adventure and Beagle' ; and Mr. Berkeley gives from 

 Mr. Darwin's MS. notes a more detailed account of his observations 

 made upon the spot. The second species is referred to in a post- 

 No. XII. — Proceedings of the Linnean Society.
