ing body is common to all, and, furthermore, with the exception 

 of Gibellula a. conspicuous bottle-shaped or subulate sporophore 

 is invariably present in some form or modification, while at the 

 same time the fusiform type of spore is present in each instance. 

 It is also to be noted that in all of the above-mentioned genera 

 with the exception of Gibellula, a viscous substance is secreted 

 apparently by the spores, which might aid them in attaching 

 themselves to new hosts, which, although not formed abundantly 

 in Sorosporella, is supposed to be present because the spures 

 cohere to one another after they are cut off. In Hirsutella, in 

 which the spores are ab jointed singly, this substance assumes a 

 rather definite form, rendering the spores falsely citriform in out- 

 line, whereas in Synnematium as has been pointed out, it is 

 secreted copiously and the successively formed spores become 

 incorporated in it, forming large glomerules. 



The characters of Synnematium are, therefore, sufficiently 

 different from other forms known to the writer to justify a new 

 name and the following description is therefore given. 



Synnematium gen. no v. 



Entomogenous. Fruiting bodies in the form of erect, den- 

 droid synnemata, arising directly from the body of the host, at 

 first white, later brownish in color. Sporophores borne laterally 

 and terminally on the synnemata, the lateral ones occurring 

 singly, the terminal ones fasciculate, sessile, uniformly and gradu- 

 ally attenuated from base to apex. Spores fusiform, hyaline, 

 one-celled, ab jointed successively, cohering in glomerules of 

 mucus at tips of sporophores. 



Synnematium Jonesii sp. nov. 



Synnemata 5-10 mm. high, 100-200 microns in diam. At first 

 whitish, flocculent, later brown and almost coriaceous, much 

 branched, often tree-like. Sporophores in part arising as lateral 

 branches of the elements of the synnemata, in part forming the 

 terminal growth of the fruiting stalk, in the first instance occur- 

 ring singly, in the second being fasciculate; in both cases non- 

 septate and clearly differentiated from the synnemata. Sporo- 

 phores 40 microns long, gradually attenuate upward from base, 

 which is 34 microns in diameter. Spores fusiform, hyaline, one- 

 celled, 8^10 by 4-5 microns, borne successively and cohering after
