subtruncate and distinguished only by its paler color. Spores about 

 35 X S/JL. Perithecium, including opaque area, 100-130 X 18 fx. 

 Longer appendages to tips of branchlets 50-70 X 5 fx. Total length 

 140-175 jjL. Main body of receptacles about 50 X 28 /x, including foot. 



On the elytra of llijliofa Chilcnsis. No. 1490, Corral, Chile. 



This species is closely related to C cylindrocarpus, and may prove 

 only a compacted variety of this species, although its appearance is 

 very different. The general form of its receptacles is very similar to 

 that of species of Tcratomyccs, and the cells are so closely associated 

 that the details of their arrangement are very difficult to determine. 

 Its fundamental structure, however, is entirely similar to that of other 

 species of the genus. The basal cells of the primary branches appear 

 to produce secondary branches, or perithecia, on both sides. The 

 antheridia are of the usual type and commonly terminal. 



CucuJOMYCES CYLINDROCARPUS Spcgazzini. 



This species was found in abundance at Corral on Hyliota Chilensis, 

 and differs from the preceding form in its free normal secondary re- 

 ceptacles, which develop right and left in the usual fashion. The 

 branches are entirely similar in general character, and the basal cell 

 ordinarily produces a branch or rudimentary perithecium which may 

 eventually develop, on both sides. The pel'ithecium is similar, but 

 more slender and cylindrical, its stalk hyaline, well developed and 

 distally rather abruptly constricted below the small opaque area which 

 subtends the perithecium and involves the small secondary stalk- and 

 basal cells. The antheridia are similar in both cases. 



CucuJOMYCES MELANOPUS Spegazzini. 



Numerous specimens of a form which appears undoubtedly to belong 

 to this species were found for the most part on the antennae of Hylioia 

 Chilensis at Corral, No. 1452 d, and although it does not correspond 

 in all respects to Spegazzini's figure and description, its resemblances 

 are too striking to be accidental. The banded perithecium with its 

 opaque base and stalk-cell, as well as the hyaline bulbous base of the 

 latter are entirely similar. The basal cell is colored, and forms a 

 broad, free, rounded, tongue-like projection lying posterior to the 

 subbasal cell; which bears not only the primary appendage and
