 contracted when dry, up to 1 mm. across ; stem very short, 

 firm ; hypothecium and excipulum formed of much inter- 

 laced, hyaline, slender hyphae ; cortex parenchymatous ; asci 

 narrowly cylindric-clavate, 8-spored ; spores irregularly 

 2-seriate, hyaline, smooth, continuous, straight or usually 

 slightly curved, narrowly cylindrical, 6-10 X 1*5 ft; para-

Specimens examined in Fuckel's Fung. Ehen., n. 2078. 

 • Distinguished by the minute, thin, tough ascophore having 

 the margin more or less wavy, and the small spores. The 

 previous existence of Helotium sordidum, Phil., a New Zealand 

 species, necessitated a change in the specific name of the 

 present species, when transferred to the genus Helotium. 

 Saccardo — Syll., vii. n. 1112 — states that the present species 

 is called Helotium sordidum by Rehm, Ascom., n. 414, and if so 

 would have had priority over Phillips's name ; this statement, 

 however, is a mistake ; Eehm calls the fungus Pezizella sordida.
