rounded, bent sidewise; a small stalk-cell clearly distinguished. Peri- 

 thecium 38 X 10 m- Appendages 6 X 2.5 m- Total length SO X 24 m- 



On the tip of the abdomen of Coproporus latus Motsch. No. 2381, 

 Mindanao, P. I. 



Three specimens of this species have been examined in which the 

 spores are not fully matured in the asci. It is most nearly related to 

 the two preceding species, especially to R. introvcrsa, from which it is 

 distinguished by the finger-like termination of its anterior cell-series, 

 its differently shaped perithecium, more numerous cells, etc. More 

 fully matured perithecia may show some fvu'ther modification of the 

 tip.' 



Rickia inclusa nov. sp. 



Nearly symmetrical, except for the prominence of the distal cells 

 of the anterior series; spathulate in habit. Receptacle subhyaline, 

 except the lower appendiculate cells, triseriate, the basal cell short 

 and stout: anterior series consisting of about twenty-five cells all, 

 except the three terminal ones, cutting off distally and externally 

 single triangular cells; the lower of which are flatter, broader and 

 more sharply pointed inward, becoming deeply suffused, contrasting, 

 and not differentiated from the bases of the appendages; the cell just 

 below the base of the perithecium larger than the rest; the thirteen 

 cells above it in contact with the perithecium, subequal, the two sub- 

 terminal cells equal, flattened, obliquely tilted; the terminal one 

 pointed inward distally and externally, forming a rounded free promi- 

 nence: posterior series resembling the anterior in general, consisting 

 of twenty subequal and subtriangular cells, the last cell cutting off a 

 relatively large basal cell which, together with its appendage, is bent 

 inward against the base of the primary appendage, the lowest cell of 

 which is rounded and somewhat larger than the uppermost cell of the 

 median series which it terminates: median series consisting of twenty 

 cells, the six lying below the perithecium larger, irregularly rounded 

 and subequal, the rest in contact with the perithecium, much smaller, 

 rounded and subequal. Appendages small and appressed, blackish 

 brown externally, bent upward at the more deeply suffused base; 

 the cells which bear them, from below up to the base of the perithe- 

 cium on the anterior side and to its middle on the posterior, also opaque 

 and contrasting. Perithecia a little anterior in position, straight, 

 erect, nearly symmetrical, fusoid-elliptical, broadest in the middle, 

 completely enclosed by the receptacle, except the partly free short
