The new species P. S^nithianiim was found on Einpetrum nigritm 

 in various parts of Scqtland. It resembles Sphaeropesia empetri 

 but differs in spores and paraphyses. A. D. Cotton (Kew).

 Myc. Sog., Season 1908 [1909]. p. 92—99.) 



Notes are given on Leptosphaeria Chondri (Rostr.) Rosenv. which 

 is recorded as British for the first time. 



The fungus noted by Church in Ascophyllum (Ann. Bot. 1893) 

 is described and is named Mycosphaerella AscophyUi. Quite young 

 plants of Ascophyllum are infected and the mycelium is found in 

 all parts of the plant. Infection apparently always takes place during 

 the earliest stages of the existence of the hostplant but the manner 

 of this infection was not ascertained. The fungus is abundant in 

 Britain, ever}' specimen of Ascophyllum hitherto examined con- 

 taining mycelium; it was also found in specimens from France, 

 Germany and Sweden. 



In conclusion a resume is given of what is known as to other 

 marine Pvrenomycetes, together with a füll bibliography.

Petch, T., Thegenus Chitoniella. (Ann. Ro5^ Bot. Card. Perade- 

 ni3'a. IV. 4. Dec. 1908. p. 112—122. 2 plates.) 



The author gives a revised and detailed account of Chitoniella 

 poderes (B. & Br.) F. Henn. based on the study of fresh material. 

 He points out many errors in previous descriptions and shows 

 Psalliota pedilia B. & Br. and P. tvachodes B. & Br. to represent the 

 same plant. The spores are pip-shaped, olive green in mass, pale 

 green when magnified, 6—8X3 — 4(U. The paper concludes with a 

 discusion on other green spored Agarics. A. D. Cotton (Kew).

A list with critical notes of new or rare British Hyinenoinycetes 

 and Ascomycetes. Three new species are described viz. Tricholoma 

 luteocitrinum Rea, Hydnopsis faririacea Rea, and Helotium tetra-
