Supplement of the Hemibasidii. 



Graphiola. 



It is possible that this genus does not belong to the Hemibasidii 

 but, as a rule, it is placed there as no better place for it has been 

 found as yet. Hohnel, however, considers it the conidial stage of a 

 species of Ustilagineae.

The mycelium penetrates the host, and the fungus causes some 

 damage to Phoenix in the nurseries ; it was first 

 found in Denmark in 1898 and may now occur 

 in most nurseries. Concerning its place in the 

 system see Fischer 83, Juel 97, Hohnel 09 »^l

 ensis. B. R0nne (Chr. Johansen). 



Sorosphaera. 



Sorosphaera was formerly reckoned among 

 the Ustilagineae but is now considered a Myxo- 

 mycet (see Maire 09). Still I think it fitting to 

 mention it here as Raunkiaer has not mentioned 

 it among the Danish Myxomycetes.
