ii shallow cup supported on three short legs, one continuous 

 with each arm. This is the general case, but in some instances 

 the " legs " are more numerous, and it is evident from these 

 exceptions that there is an additional chamber superposed on 

 the arms at the node, and that its lateral wall is perforated to 

 such a degree that only three narrow strips remain in most 

 cases. The sporiferous mass is confined to the concave upper 

 surface of the cup. The spores are narrow-oval, 4 X l-gf*. 



In unopened specimens, 5 mm. diameter, the receptaculum 

 is closely applied to the volva, and the nodes are already 

 covered with the separate spore masses. Specimens 3 mm. in 

 diameter have the olive, convoluted gleba intact, surrounded 

 by the crumpled receptaculum, and it can be determined by a 

 series of sections that only the nodes of the net come in contact 

 with the gleba. When the gleba deliquesces the spores there- 

 fore adhere only to the nodes. In Clathrus crisjMtus the whole 

 of the net is in contact with the undeliquesced mass of trama 

 plates and spores. 



The expanded receptaculum is pure white. The jelly 

 remains within the volva, and as in all phalloids, the recepta- 

 culum after maturity is free from the volva, and is only held in 

 position by the jelly. It has no appreciable smell. 



This species appears to agree with Ileodictyon in the folding 

 of the young unexpanded receptaculum, and the general 

 absence of folds on the individual brandies when expanded. 

 But in the collection of the spore masses at the nodes of the net, 

 the distinct tube at the base of the receptaculum, and the fur- 

 rowed outer surface of the branches it is undoubtedly nearer to 

 Clathrella. ' The differences between the two genera, however, 

 hardly seem to warrant any distinction. Clathrella delicata 

 appears to resemble Clathrella chrysomycelina (Moller), from 

 which it differs in the colour of the mycelium, smaller size, 

 and the structure of the arm which produces the external 

 furrow. The Rev. A. Schupp, however, states that the 

 mycelium of C. chrysoniycelinus is not always yellow. 



A rectangular piece of bamboo about 14 cm. X 12 cm., on 

 which were several developing specimens was placed in a glass 

 dish in the laboratory. On July 7 all the developing specimens , 

 which grew chief!}' along one edge, were removed, and the
