taneously into fragments. Is Clathrus crispatus to be described 

 as a heap of fragments? It would appear self-evident that if 

 classification is to be based on the general shape of phalloids, 

 it must be on the perfect shape, immediately after expansion, 

 before they have collapsed or broken. 



The type species of the genus Lysurus, L. Mokusin, appears 

 from the available figures and descriptions to be so different 

 from the other species assigned to Lysurus, that it would seem 

 preferable to confine the genus to it alone. From the photo- 

 graph of Lysurus boreal is in Lloyd, Myco. Notes, p. 513, it 

 appears clear that that species has wrinkled arms similar to 

 those of Lysurus australiensis. From Fischer's description, 

 and Holler's figure as reproduced by Lloyd, Lysurus Clarazianus 

 has the same wrinkled arms. Of the remaining species 

 enumerated by Lloyd, Lysurus Woodii (MacOwan), L. Sanctae- 

 catharinae (Ed. Fischer), and Lysurus cruciatus, there does not 

 appear to be any definite information regarding the structure 

 of the arms. 



The type species of the genus Coins is Colus hirudinosus 

 Cav. & Sech. Its short stalk divides above into several stalk- 

 like arms, which support a netted head. Hence Fischer was 

 justified in comparing Lysurus Gardner i to a Colus in which 

 the apical meshes had disappeared. Its arms appear to be 

 transversely wrinkled. 



The genus Pseudocolus is attributed, in Saccardo, xxi., to 

 Fischer, but it was apparently established by Lloyd, Phalloids 

 of Australia (1907), p. 18, for the reception of Colus Rothae 

 Fischer, Colus javanicus Penz., Colus Garciae Moll., Colus 

 fusiformis Fischer, and Pseudocolus rugulosus. These species 

 have a short stalk which bears three arms, united at the apex. 

 It may be noted that unless the genus Pseudocolus is confined 

 to species which have only three arms, Lysurus Gardneri 

 should, if the general shape of the plant alone is considered, 

 have been included in it ; Fischer, indeed, grouped Colus 

 [Lysurus) Gardneri with Colus javanicus and Colus Garciae. 

 Length of stalk can scarcely be regarded as a generic difference. 



Pseudocolus Rothae is insufficiently known ; its arms are 

 described by Fischer as wrinkled, but Cleland and Cheel state 

 that the species they attribute to this has arms which are 

 alv^eolar on their inner surface. Pseudocolus Garciae, from 

 Moller's figure and description, has coarsely wrinkled arms. 

 Pseudocolus javanicus is described and figured by Penzig as 

 having lamellae in groups on the arms. Pseudocolus fusiformis 

 and Pseudocolus rugulosus have not been adequately described 

 or figured. 



On the available evidence, none of the species of the genera
