THE GENUS GIBELLULA CAVARA, 
A. P. MORGAN. 
In Michelia I, 83, Saccardo described a Hyphomyces, which 
he named Corethropsis pulchra, stating that it grows on dead in¬ 
sects and their Isaria. In his Mycologie Lombarde Cavara takes 
the view, if I may judge from the brief exposition in Sylloge XI, 
643, that the Isaria and the Corethropsis are to> be taken together 
as one plant; upon this he founds his ^enus Gibellula. Saccardo 
appears to concede this view to be correct. Then it is also very 
probable that Corethropsis australis Speg. is simply the sporif- 
erous hyphae of Isaria arachnophila; this is the inference we 
would make from the observation of Oudemans concerning the 
latter species, quoted Sylloge IV, 587. Should the type species, 
Corethropsis paradoxa Corda, turn out to be a similar organism, 
Cavara’s genus will be canceled and Corethropsis will take its 
place among the Hyalostilbeae. Bonorden’s figure labeled Stachy- 
lidium paradoxon certainly suggests this disposition of the spe¬ 
cies. I can not refer to the Prachtflora but Corda in leones V, 14, 
describes a “stroma.” 
Without knowing just how the genus Gibellula or Corethrop¬ 
sis is going to be defined, I venture to contribute to it the follow¬ 
ing species. I assume that the so-called “basidia” and “sterig- 
mata” are the lower and longer joints or spores of a chain 
proliferously developed, as in Cladosporium for example.
