199. Doidge, Ethel M. Meliolaster, a new genus of the Microthyriaceae. Trans. Roy. 

 Soc. South Africa 8: 121-123. 1920. — This is a genus resembling Meliola in its mycelium and

■ 200. Matstjmoto, T. Culture experiments with Melampsora in Japan. Ann. Missouri 

 Bot. Gard. 6: 309-316. Fig. 1-3. 1919. — Cross inoculations of teliospores of a Melampsora 

 from Salix Urbaniana on Larix decidua and caeomaspores from L. decidua on S. Urbaniana 

 were successful. Melampsora Larici- Urbaniana is described as new. M. Larici-populina 

 Kleb. is found in Japan on Populus balsamifera. A species on Salix babylonica, having a 

 caeoma stage on the leaves of Chelidonium majus, has not been definitely placed taxonomic- 

 ally, while a Melampsora on Salix Capraea seems to have a caeoma stage on the leaves of 

 neither Larix nor Abies. — S. M. Zeller.

 fruit body of this fungus was found in the bog of Montorfano and was first taken for a fruit 

 of the horse-chestnut. The walls of the hyphal strands had become impregnated with graphic 

 acid and were in a perfect state of preservation. — E. Artschwager.

 illicina (Syd. et Butl.) Syd. previously described as Pleomassaria ilicina Syd. et Butl. ;

 Syd. previously called Julella intermedia Syd. ; Starbaeckiella Syd. ; Starbaeckiella massario- 

 spora (Starb.) Syd. = (Clypeosphaeria? massariospora Starb.); Starbaeckiella Mangiferae Syd.
