Herpomyces Paranensis nov. sp. 



Male individual similar to the simpler forms of H. tricuspid atus, but 

 the terminal cell distally modified to form a long slender flexuous taper- 

 ing unicellular prolongation extending above the tips of the autheridia. 

 Total length to tip of terminal prolongation 250 /x ; the prolongation 

 185 ft. Antheridia about 60-70 p. 



Female individual. Primary receptacle very small, the distal cells 

 rounded, the uppermost prolonged as in the male. Secondary recepta- 

 cles developed on either side of the primary, the cell series apparently 

 turning inward from either side so that the perithecia are more or less 

 clustered (younger ones appearing behind the two primary ones), and 

 protected by a shield-like structure external to the base of the first fertile 

 cell, developed like a buttress, the outer and upper margins of which are 

 free, consisting of sterile cells which are greatly elongated vertically 

 and very narrow, similar and successively fewer-celled buttresses being 

 formed behind the primary one in connection with each of the remain- 

 ing perithecia, of which there may be from four to six. Perithecia very 

 similar to those of the preceding species, but with the following differ- 

 ences : the greatly elongated fertile cell of the receptacle extends nearly 

 to the base of the perithecium, the posterior stalk-cell extending down- 

 ward beside it nearly to its base, covered by the protective shield except 

 at its distal end, which is connected by a narrow isthmus with an abrupt 

 short broad terminal enlargement ; the anterior stalk-cell small, short, 

 subtriangular in outline ; the base of the perithecium abruptly somewhat 

 broader, its cells protruding more or less distinctly ; the ascigerous region 

 thus somewhat clearly distinguished, especially posteriorly, relatively 

 distinctly larger than in the preceding species, somewhat inflated ; the 

 conformation of the distal portion similar in general, but the third wall 

 cell of the anterior row is not modified to form a prominence at the base 

 of the anterior spiniferous cell, the upper half of which forms a free spi- 

 nous process slightly incurved distally and equalled or even exceeded by 

 the lateral spinous process : the free tip of the perithecium about twice 

 as long relatively, slightly incurved, the erect incurved spinous process, 

 which subtends it externally, more than twice as long as that of the pre- 

 ceding species and sublateral ; the tip between the base of this spine and
