Algae. — Fungi. 207 



The author describes and figures stages in the life- 

 history of Aphanochaete (Herpostelron) polychaete Fritsch, but 

 is unable as yet to give any details concerning its reproduction. 

 An account is given of the work done and views held by other 

 authors on this genus and neighbouring genera and a scheine 

 of Classification is added. The author finds that the hairs of 

 species of Herpostelron are not septate, nor is there proof of 

 the presence of a sheath at their base and he consequently 

 transfers H. confervlcola Näg. and H. polychaete Hansg. into 

 Aphanochaete. The genera Chaetosphaertdtwn, Dtcoleon and 

 Conochaete of Kleb ahn are maintained. He notes the frequent 

 occurrence of cells with red, granulär contents, in connection 

 with A. polychaete; but has as yet no clue to the part they play 

 in its lifehistory. He has found similar cells while examining 

 young plants of Stlgeoclonlum. Ethel S. Gepp (nee Barton).

 Oedogonlum. (Annais of Botany. Vol. XVI. No. LXII. 

 June 1902. p. 412—417. fig. 23.) 



The author describes this occurrence in 0. caplllare Kütz. 

 His observations do not agree in certain points with those of 

 K ü t z i n g or of P o u 1 s e n. He finds that the first cap is not thrown 

 off in O. caplllare and in other undetermined species examined 

 by him this is also the case. Ethel S. Gepp (nee Barton).

The author incorporates here all the latest records, inclu- 

 ding the results of his examination of the National and other 

 Herbaria, and brings the nomenclature up to date. Only such 

 synonomy is given, as is necessary for the recognition of a 

 species. The distribution of each species is given and a note 

 as to its frequency. Up to the present time the Orders 

 Myxophyceae, Chlorospermeae and part of Fucoldeae have appe- 

 ared. E. S. Gepp (nee Barton). 



HOLTERMANN, CARL, Fungus cultures in the tropics. (Ann. 

 Roy. Bot. Garden Peradeniya. I. Dec. 1901. p. 27. pl. 1.) 

 The author discovered that the excreted gum of the sugar 

 palms Arenga saccharlfera and Carytoa urens, when diluted 

 in water and properly sterilized, proved an excellent medium 

 for the cultivation of different genera of fungi. During the rainy 

 season almost every thing is infested with the spores of fungi in 

 the tropics, and the most certain method of securing steriliza- 

 tion was found to be that of keeping instruments, cover slips, 

 microscopic glass slides, in fact every thing, in alcohol. These 

 are taken out of the spirit and passed through a flame imme- 

 diately before using.
