40 Mr. Berkeley on an edible Fungus from Tierra del Fuego, 



lost their expulsive property, and rotted. It perhaps forms a new genus, ap- 

 proximating to the Sphwrice. Its vulgar name is Digntnes. Some persons eat 

 them, but their insipid and styptic taste is disagreeable." 



Cyttaria. 



Receptacula carnoso-gelatinosa in stroma commune subglobosum, epidermide crassiuscula, 

 vestitum, aggregata; basi stipitiformi granulata. Cupula peripherica, primo clausa, 

 gelatina distenta, demum epidermide rupta aperta. Hymenium, margine excepto, sepa- 

 rabile. Asci ampli, distincti, demum liberi, paraphysibus immixtis. Velum persistens 

 demum ruptum, margine plus minus reflexo. Sporidia pallida. 



Genus Bulgarian affine, sed stromate pulvinato ex variis individuis composite SpliEeriam con- 

 centricam quodammodo referente, et hymenio separabili valde diversum. Certe ad se- 

 nern Pezizarum pertinet, perithecio spurio non obstante. Confer Sphieriam mono- 

 carpam Schum. ad Pez. rhizopodam a clar. Friesio ascriptam. Nomen dedi a ^rrapo, 

 ob superficiem fungi alveolatam.
