moulds and other fungi. The leaves of Raciborski's specimens 

 are quite clean, and the fungus is sparsely scattered and attached 

 directly to the leaf. The same is also true of some specimens of 

 A. dominicana, this being particularly the case in the second 



batch forwarded. 



Raciborski notes an interesting point with regard to the produc- 

 tion of spores in A. Millardeti ('09 p. 370). He states that the 

 formation of asci appears to coincide with the advent of the East

material. The first batch forwarded (collected November, 1912) 

 was either sterile or contained conidia only ; the second gathering 

 (collected in February, 1913) possessed conidia in abundance; 

 whilst in the third supply (collected March 15, 1913), almost every 

 specimen is in full ascigerous fruit, though old conidial cavities 

 are also visible. Seasonal development of spores was also noted 

 by Neger in the plant he examined in Chile (see later).

Systematic and Ckitical. 



As far as fungi that have been described under the name of 

 Atichia and Seuratia are concerned little revision is necessary, 

 but in order to make the survey of the family as complete as pos- 

 sible, other plants which have been detected as possibly represent- 

 ing species of Atichia are considered below, and in most cases 

 the original material has been obtained and examined. 



With regard to the plants described by French authors, 

 Phycopsis VaniUae is undoubtedly a very marked species and well 



worthy of the generic rank assigned to it by Mangin et Patouillard. 



Seuratia Tondvziy specimens of which were kindly sent by Prof. 

 Mangin, is distinct in its large size and botryoidal propagula, but 

 on the grounds of priority it should be known as Atichia TonduzL 

 The identity of S. coffeicola, Pat. with A. Millardeti^ Rac. had 

 been proved by von Hohnel, who examined type specimens of both 

 species, but with the publication of fuller details (Mangin and 

 Patouillard, '12) a few points arose which required re-investiga- 

 tion. Prof. Raciborski kindly forwarded a portion of his original 

 material, the examination of which placed the identity of the two 

 plants beyond dispute, the detailed drawings of the French 

 authors agreeing in every particular with the Javan plant. 



Various Hyphoviycetes were next examined. Von Hohnel 

 pointed out the possibility of Torula Lechleriana being a member 

 of the genus, and also Heterohotrys jparadoxa. In response to a 

 request Prof. P. A. Saccardo was kind enough to send the original 

 specimens on loan to Kew, and also R. paradoxa subsp. chilensis 



Sacc. and Syd. The examination of these gave the following 

 results: — 



+ _ 



Torula Lechleriana, Sacc. Not an Atichia, but apparently 

 riglitly placed by Saccardo in tlie genus Torula. . 



Heterohotrys j)arado.m, Sacc. In Sylloge xxii. p, 769, Saccardo 

 suggests ttat tins plant is a synonym of A. Tonduzi, w-bereas von 

 Hohnel had proposed the name A. paradoaa sp. no v. ('10, p. 27). 

 The type shows that it is an Atichia and closely allied to a! glome-
