sessing the peculiar structure of Atichia. He names it Atichiopsis 



Solmsii, preferring not to link it more closely with Flotow's genus. 



The full description .promised was not published, A few months 



previous to this, Eaciborski, in the third instalment of his notices 



on Javan fungi, includes a brief account of A. Millard ctiy sp. nov, 



('00, p. 41). He states that the fungus is common in Java on 



various hosts, and describes the asci, which contained two-celled 



coloured spores, as occurring in a layer under the surface of 



special swcllen portions of the thallus. His account, though brief, 



is more detailed than Wagner's, and it was followed some years 



later by a full description ('09, p. 369). The general structure of 



the fungus agreed so exactly with Atichia glomerulosa that there 



was no reason to regard it as generically distinct. According to 



von Hohnel, Wagner's plant is the same as Raciborski's but his 



name Atichiopsis Solmsii a nomen nudum^ hence, he states. A, 



Millardeti has priority. Apart, however, from this point, Raci- 



borski's name must stand in preference to Wagner's as it antedates 



his by a few weeks. 



With the exception of von Hohnel's paper to be noted imme- 

 diately the other contributions to our knowledge of the genus have 

 been made by French botanists, who have dealt with it under the 

 name Seuratia. This genus was proposed by Patouillard in 1904 

 for a plant obtained by Seurat in Gambier Islands (Polynesia), 

 and a single species, S. coffeicola, was first described. As 

 explained later, this plant is the same as A. Millardeti^ Rac. 

 Seuratia was placed by Patouillard amongst the Ca^ptiodiaceae^ 



though he notes that it differs from the other genera in several 

 particulars, namely, in the absence of superficial mycelium, the 

 gelatinous consistency, and the peculiar dehiscence. In 1905, 

 however, Yuilleroan made it the type of a new family, and at the 

 same time described S. piiiicola sp. nov. on Pinus halepensis in 

 the South of France. This plant is obviously, as von Hohnel 

 remarks, the ascigerous stage of the original A. glomerulosa. The 

 following year Patouillard described another species, from Tahiti, 

 S. Vanillae, on leaves of Vanilla planifolia (*06). Yon Hohnel's 

 useful paper appeared four years later, though it was preceded by 

 a note in his Fragmente ('09, no. 333). In the paper he sum- 

 marises previous work, points out the identity of Seuratia with 

 Atichia J and describes A. Treuhii sp. nov. from material collected 

 by himself in Buitenzorg, Yon Hohnel also removes the Hypho- 

 mycete Hetcrohotrys paradoxa, Sacc, to the present genus, and, 

 though he did not apparently see the specimen, proposed the new 

 species A, paradoxa. 



The latest contribution to the subject is by Mangin and Pat- 

 ouillard ('12), who give for the first time a full and illustrated 

 account of the several reproductive bodies. These authors retain 

 the genus Seuratia Pat,, hut remove the plant previously described 

 by one of them as S, Vanillae to a new genus Phycopsis, on account 

 of the very distinct manner in which the clusters of conidial cells 

 are produced. They also describe the new species A. Tonduzi.^
