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



corresponding with the sides of the aperture. Asci more slender and longer than in 

 the last ; sporidia elliptic, smaller, separated by a granular mass. The flesh in the 

 full-grown plant, which alone I have seen, is mottled, consisting of branched flexuous 

 filaments. There are a few black granules about the base. 



This species is clearly very distinct. I have described the asci and their 

 contents as observed in specimens preserved in spirits. They are very different 

 from those of Cyttaria Darwinii. The colour of the cuticle in the preserved 

 specimens is brown, so that they strongly resemble potatos. In the other spe- 

 cies the preserved specimens are nearly colourless.

EXPLANATION OF TAB. IV. 



Cyttaria Darwinii. 



Fig. A. Cyttaria Darwinii, in various stages of growth. 



a. Young specimen. 



b. Large specimen, before the hymenium is perfected. 



c, c. Specimens in which the hymenium is perfected but the epidermis not yet rup- 

 tured. 



d. Elongated form, in which some of the cups are perforated. 



e. Full-grown specimen, with all the cups exposed. 



1. Section of (a.) magnified. 



2. Portion of the substance, highly magnified. 



3. Section of stem, magnified to show the granules. 



4. Section of specimen resembling (6.), in which the hymenium is scarcely perfected. 



5. Section of a small specimen in which the hymenium is perfected and the cups 



perforated. 



6. Portion of substance of ditto, from between the cups, with a fragment of the epi- 



dermis attached ; highly magnified. 



7. Section of one of the cups magnified, in which the hymenium is just perfected, 



showing that the cup is lined with it nearly throughout. The part above (;8,/3) 

 is at length confluent with the epidermis, and bursts.
