THE GENUS HOLOCOTYLON. 



Since the publication of this genus we have received additional 

 abundant material of Holocotylon Texense from J. W. Stiles, Hunts- 

 ville, Texas. These specimens fully confirm 

 the marked distinction of the genus Holocoty- 

 lon from Arachnion, which at one time we 

 were disposed to doubt on account of their 

 close general resemblance. Fig. 112 made 

 from the ripe gleba (enlarged ten diameters) 

 will give a good idea of the gleba structure 

 of the genus Holocotylon. Mr. Stiles also 

 finds Arachnion album and writes me : "These 

 two plants, Nos. I and 2 (Holocotylon Tex- 

 ense and Arachnion album) very much re- 

 semble each other in external appearance and 

 habits of growth. They were collected within 

 fifty yards of each other but in entirely dif- 

 ferent groups and unmixed." Several 

 years ago we received from Martinez 

 Solerzano, Morelia, Mexico, some young 

 specimens that we were unable to locate. 

 They evidently belong to the genus 

 Holocotylon and the photograph (Fig. 

 113 enlarged four diameters) will give 

 a 1 :cttcr idea of tin- structure of the 

 ^BHH^H^Kj gleba of Holocotylon than our previous 

 ^^^^B^HHKf figures. Mr. Solerzano's specimens are 

 about the same size as Holocotylon Tex- 

 ense, and may be young of this species, 

 -f^-*** but they seem much firmer in texture and 



we desire to see ripe specimens before 

 forming any opinion as to their specific

LYCOPERDON WRIGHTII IN AFRICA AND 



JAVA. 



We have just received from Dr. K. Braun, German East Africa, 

 a collection of this unique little species, hitherto only known from the 

 United States. The large, hyaline, flaccid, septate capillitium such as 

 no other species typically has, readily character- 

 izes the plant. The African plant differs from 

 the American in one character which to my mind 

 is not material. The American plant has smooth 

 spores ; the African plant has spores which under 

 a high power are very slightly rough. I might 

 Fi s- 114 - therefore base on it a "new species" on the same 



principle that the wonderful Lycoperdon pseudo-pusillum was recently
