(2) II y a continuite manifeste entre les filaments dresses 



et les filaments rampants. 



(3) Lorsque, comme I'un de nous I'a fait sur place, on met 



dans un tube sterilise, des pelotes-conidies et des 

 fragments de meule bonillis, les pelotes, qui 

 incontestablement appartiennent a la " forme 

 rase," donnent la " forme envahissante." 



With regard to these reasons, it may be remarked that as the 

 authors state that they were unable to obtain any germination 

 of the conidia of the " pelotes " (spheres), the mycelium must 

 have developed from that of the sphere, and under such 

 conditions it is impossible to be certain that the mycehum of 

 one species only was transferred to the tube. The second 

 reason is based on an observation which would be impossible 

 in the cases examined in Ceylon, while the first applies equally 

 well to any of the three mycelia which must be always present 

 in the combs of the Ceylon species. 



The sclerotia obtained from the nests of Termes perrieri 

 were always small, and no attempt appears to have been made 

 to grow anything from them. But a Xylaria was found 

 growing from abandoned termite nests, and that is regarded 

 by the authors as the fructification of the sclerotium, and 

 hence of the " forme envahissante " of the mycelium, a view 

 which is no doubt correct. Jumelle and Pcrrier de la Bathie 

 name their Xylaria, X. termitum, but from their figures and 

 descrij^tion it is certainly Xylaria. nigripes. Probably a 

 further search would result in the discovery of larger sclerotia, 

 from which the Xylaria could be developed in the laboi*atory. 



It is to be noted that according to this view the spheres on 

 the com!) are a cionidial form of the Xylaria. That the " forme 

 envahissaiitc " of the mycelium is the mycelium of a Xylaria 

 agrees with T'cylon experience, but that it is merely a 

 continuation of the " forme rase " is open to question. 



Collected Observations. 



From the fttregoing brief summaries of the work of the 

 djlierent luycologists and entomologists who have recorded 

 observations on the fungi of termite nests, it will have been
