72 SUMMARY OF CURRENT RESEARCHES RELATING TO 



collected by Munier-Chalmas at Namur and preserved in Mom. Bornet's 

 herbarium. The material has been known as Lithothamnion marmoreum. 

 Foslie has, however, found in the specimen two species, one of which 

 he describes as ArchseolUhothamnion marmoreum and the other as Lttho- 

 phyllum (?) belgicum. The latter is without conceptacles, but it approaches 

 Lithophyllum in its structure. The geological period of these two species 

 is unknown. 



Finland Algae.*— E. Hayren gives a short list of algaj from the 

 west coast of Finland, in the neighbourhood of Bjomeborg. The list 

 consists of 26 species, of which 8 are Chlorophyceas, 10 Characete, 

 5 Phteophyceae, and 3 Rhodophyceas. They constitute the first records 

 from that coast.

Fungi. 



(By A. Lorrain Smith, F.L.S.) 



Rhizopus Batatas, a New Koji Fungus.f— The preparation of Koji 

 by the aid of a species of Aspergillus was affirmed by K. Saito, who 

 also found Rhizopus chinensis Saito in the material, and judged that 

 the latter took little part in fermentation. The fermenting agents have 

 been re-examined by R. Nakazawa, who affirms the importance of Asper- 

 gillus, but claims to have discovered a new Rhizopus which also aids in 

 fermentation : he has named it R. Batatas. It possesses larger sporangia 

 and spores than the species recorded by Saito, but differs more especially 

 in its power to ferment in pure dextrose, maltose, saccharose, and lactose. 



Evolution of the Lower Fungi.}— G. F. Atkinson has discussed a 

 series of problems in this connection. He gives the views held by 

 various writers, Pringsheim, De Bary, Brefeld, Dangeard, and others ;
