Rosellinia lamitiariana, n. sp., found on fronds of Laminaria, 

 is described as a species almost intermediate between Rosellinia 

 and Sordaria. 



Pleospora laminariana n. sp. is also recorded on cast up Lami- 

 naria fronds. 



For a third new species, occurring on living Fucusvesicidosus, 

 a new genus, Lulwortlna, is constituted. Liüworthia fncico^a is 

 characterised by large globose perithecia, at first immersed but 

 finally free, without evident ostiole. The asci contain eight hyaline 

 elongated continuous spores, wilh appendages, and are unaccom- 

 panied by paraph3'ses. The genus approaches most nearly to Mas- 

 salongiella in the MycosphaercUaceae, and also shows some resem- 

 blances to Dilophia among Pleosporaceae. 



A species of Orcadia is described which was noted on Fucus 

 vesictUosus, but Ihe author is not certain whether it is distinet from 

 O. pelvetia:ia. 



Fuli descriptions and critical notes are given in all cases.

West, C Sligeosporiuni Marattiaceanim , gen. et sp. nov. (Ann. 

 Bot. XXX. p. 357. April 1916.) 



The fungus of which the diagnosis only is given here was 

 found living symbiotically in the roots of various genera of the 

 Marattiaceae. It is said to be allied to Phytophthora, and is of spe- 

 cial interest among m3"corrhizal fungi as it produces distinct repro- 

 ductive bodies (spores) within the tissues of the host.

Im Süden von Posen trat seit 1900 eine Krankheit auf ver- 

 schiedenen KulturgeviTLicusen auf. Das Krankheitsbild bestand an- 

 fangs darin, dass die erkrankten Feldstellen einen gelblichgrünen 

 bis gelbweisslichen Farbenton annahmen und sich von ihrer Umge-
