on Lamhim album, nimierous tumour-like swellings formed on the 

 underground organs being due to the presence of the fungus. There 

 may be dark blister-like swellings on the side of the stem or tuberous 

 bodies surrounding the stem in the form of K'ataplasmic galls. The 

 author considers the genus to be a member of the Ustilagineaj. He 

 reviews the various species of Melanotieaium already published, and 

 describes more particularly the morphology and cytology of 21. Lamii. 

 The mature spore is uni-nucleate ; the hyphal cells and young spores 

 are binucleate. A. L. 8. 



Biology of Panus stypticus. — Maeie E. M. Johnson (Trans. 

 Brit. Mycol. Soc, 1920, 6, pt. 4, 348-52, 1 pL). The author thus 

 summarizes new results : — (1) The sporophores can withstand frost, and 

 so can be cultivated > in the open during winter. A sporophore takes 

 about three months in developing. (2) Spores germinate readily in 

 suitable media ; wood-block cultures in favourable conditions produce 

 sporophores in six or seven weeks. (3) Wood attacked by the fungus 

 "becomes light, very soft, and paler in colour ; the less lignified elements 

 disappear first. (4) Sporophores, after a time of desiccation, when 

 moistened, shed spores which are viable ; the mycelium also can be 

 dried for many months and still retain its vitality. A. L. S. 



New Record for Polyporus montanus Quelet. — S. Killerman 

 (Bednigia, 1910, 61, 1-3, 1 pi.). The fungus was found in the 

 Bavarian forests in large quantities and growing to an immense size. 

 It is distinguished by the ochraceous echinulate spores. It has a wide 

 distribution in Central Europe. A. L. S. 



Mycological Transactions.— (5/-//f, 3Ii/col. Soc., 1920, 6, pt. 4, 

 299-396). The present part opens with an account of the Spring 

 Foray at Painswick. Larger fungi were scarce, but other kinds of great 

 interest were collected ; 'EicMerieJ/a spinidosa was collected for the first 

 time so far south. The English records of Stereum 7-iifimiVi'eve based on 

 this plant, and other synonyms are Radulum deijluhens and R. spinu- 

 losnm. A list of the fungi collected is appended. A. L. S. 



Note on Marasmius cauticinalis. — D. Paul (Trans. Brit. Mtjcol. 

 Soc, 1920, 6, pt. 4, 344-5). The name cauticinalis has been confused 

 with caulicinalis, and the confusion may have been due to a printer's 

 error. Paul has traced the changes of the spelling through the dif- 

 ferent authors ; caulicinalis, he holds, is well-chosen and descriptive, as it 

 means growing on stalks, stems, etc., which exactly expresses the habit of 

 the Marasmius in question. A. L. S. 



■ Records of Surrey Resupinate Hymenomycetes. — E. M," Wake- 

 field and A. A. Pearson (Trans. Brit. Mijcol. Soc, 1920, 6, pt. 4, 

 317-21, 6 figs.). A descriptive list is given of a varied series of 

 " resupinates," most of them new to Britain. They were collected mostly 

 near AYeybridge. Sistotrema variecolor w'as collected at Farnborougli, 

 Hampshire, and was determined by M. I'Abbe Bourdot. It has the 

 habit of Vi Radulum, but is sufficiently distinguished by the larger, longer 

 spores. A. L. ST
