Pans there is a very poor specimen, which has been called Clathrus 

 Fischen, but which appears to be Clathrus gracilis. The specimen is 

 too poor to judge, however. Notwithstanding that Clathrus gracilis 

 is the most common phalloid in Australia, we know of no photograph 

 of it and have to resort to one made from alcoholic material, devoid 

 of volva, which gives only a vague idea of the plant. 



CLATHRUS CHRYSOMYCELINUS (Fig. 80) .-Receptacle 



white, with large, polygonal meshes; those below somewhat length- 

 ened. The receptacle arms are united at the base. Mvcelium de- 

 scribed as being bright golden yellow, hence the specific name This 

 species is only known from Brazil. Father Schupp finds it, and he 

 writes me the mycelium is not always yellow.

CLATHRUS DELICATUS. 



CLATHRUS PREUSSII (Fig. 81). This species from Kamerun, Africa, 

 i- one of the few white species of Clathrus known. The receptacle has broad, 

 Hat arms that are more narrow above. The figure which was published by 

 Fischer shows the plant with the volva cut away. It is only known from 

 the original collection in alcohol at Berlin. The bars of the network are 

 cellular (not tubular) and have a somewhat quadrilateral shape, different from 

 all other known species of Clathrus. 



CLATHRUS DELICATUS (Fig. 82). This unique little Clathrus is the 

 smallest of the genus and disputes with Mutinus xylogenus the distinction of 

 being the smallest phalloid known. It occurs only in Ceylon as far as known. 

 The color is white, and the structure of the arms is tubular, hence it should 

 be included in the genus Ileodictyon if taken out of Clathrus. The gleba is 

 collected in little globose masses at the nodes of the net.
