280 DECADES OF FUNGI. 



globose tissue, hyaline, thougli appearing black from the abundant uni- 

 serial sporidia, which are subelliptic, -^ ^qq of an inch long. 



This species is totally different from anything with which I am ac- 

 quainted. The pale substance, and absence of all carbonization, seem 

 at first to indicate H^pocrea rather than Xylaria or Hypoxylon, The 

 walls of the perithecia are rather thick, perfectly hyaline, and consist 

 of a finely reticulated tissue.

The spores of this species attain a length of ^-^ of an inch.

 liquis infundibuliformibus ; extus stipitibusque tenuibus ramosis sca- 

 briusculis. Spruce, n. 85. (Tab. X. fig. 5.) 



Hab. On decayed trunks. Panure. 



Tufted, vinous-brown, about \ Inch high. Stems slender, scabrous, 

 branched ; cups oblique, funnel-shaped, rather rough externally and 

 slightly venose ; sporidia elliptic, ^Jq^ of an inch long. 



This is nearly allied to Feziza concrescem^ Schwein., of which I should 

 have considered it a small form, but for the smaller sporidia and smooth 

 hymenium. 'The latter character however might not hold good with 

 better and more abundant specimens. I have not seen asci in that 

 species, but they are evident enough in the present. 



620. Thamnomyces fuciformis, n. s, ; stipite crassiusculo filiformi 

 flexuoso, ramulis brevibus rectis thecseformibus regulariter vestito. 

 Spruce, n. 150. (Tab. IX. fig. 3.) 



Hab. On decayed trunks. Panure, February, 1853. 



Stem cylindrical, filiform, 1 line thick, flexuous, dark brown, beset 

 everywhere with short, perpendicular branches, about 3 lines long, 

 swelling in the centre, so as to assume the form of the theca of some 

 Moss, and enclosing a single oblongo-elliptic cavity. 



This curious species at first sight resembles some seaweed rather 

 than a Fungus.

Var. similis. 



Hab. On rotten trunks. Panure. 



Differing in nothing from Dr, Montague's plant, except in the ab- 

 sence of a beaked ostiolum, a character very variable amongst Sphcsri/^- 

 It is by Dr. Montagne's advice that I refer the specimens to his species.
