Mycologia 



Saussure (1853) but the illustration was later copied by Graj 

 (1858) and still later by Cooke, the latter venturing to give it the 

 name mentioned above. In general appearance it bears a close 

 resemblance to a form on Polistes that was brought to the atten- 

 tion of the writer in Hawaii, which is closely allied to Hirsutella 

 entomophila, and although no microscopic characters of /. satis- 

 surei were ever recorded, there seems to be no good reason for 

 considering it different from the Hawaiian and other forms 

 mentioned below. 



The writer (191 2) considered under the name " Sterile Cordy- 

 ceps " a fungus that was found upon specimens of Perkinsiella 

 saccharicida in Hawaii, and at that time being unfamiliar with 

 Patouillard's paper did not suspect the now evident relationship of 

 this form with Hirsutella entomophila. 



The description and figures by Vosseler (1902) of Isaria suri- 

 namensis sp. nov. and Isaria gracilis sp. nov., two species occur- 

 ring on Amphonyx cluentus and Anthophora sonata respectively, 

 clearly show a resemblance to the fungi herein considered. In 

 gross appearance, in the microscopic structure of the synnemata, 

 both of these forms show characters in common with those of 

 Hirsutella, and while the sporophores appear at first sight some- 

 what different from the analogous organs of Hirsutella, it should 

 be noted that in old specimens of the latter only the basal portions 

 of the sporophores persist and that the attenuated terminal por- 

 tions are somewhat delicate and disappear after the spores are 

 formed. Furthermore, in many instances development of the 

 sporophores seems oftentimes to be arrested so that only the 

 stump like inflated basal portions are formed. In such cases a 

 condition, Plate 3, Fig. 6, is brought about that is quite like that 

 illustrated by Vosseler on his Plate VIII, Figs. 3 and 9. 



Vosseler has not made clear either by figures or by text, how- 

 ever, the nature and method of formation of the bodies which he 

 calls the spores. His illustrations of these bodies show no re- 

 semblance to the spores of Hirsutella, and on account of the fact 

 that he was unable to show how they were formed, it is evident 

 that he possessed old specimens in which the true fruiting stage 

 had disappeared, and that the spores which he described should 

 probably not be associated with the fungi mentioned.
