species, 1 being new, and Didymosphaeria Sacc, with 3 new species. [For abstract of entire 

 paper see Bot. Absts. 10, Entry 1249.] — H. M. Fitzpatrick. 



1243. Whitehead, T. On the life history and morphology of Urocystis cepulae. Trans. 

 British Mycol. Soc. 7: 65-71. PL 2. 1921. — Urocystis cepulae, which causes a destructive 

 smut disease of onions, has a relatively simple life history, chlamydospores giving rise to 

 promycelia which develop sporidia laterally. Infection probably takes place through root 

 hairs in the collar region of seedlings. — W. B. McDougall. 



1244. Wilson, Malcolm. Notes on new or rare British fungi. Trans. British Mycol. 

 Soc. 7: 79-85. 1921. — This paper contains notes on Dasyscypha calyciformis (Willd.) Rehm, 

 Hypoderma pinicola Brunch, Hypoderma brachysporum (Rostr.) Tub., Cronartium ribicola 

 F. de Waldh., Melavipsorella caryo phyllacearum Schrot., H apalosphaeria deformans Syd., 

 Melasmia empetri Magn., Botrytis douglasii Tub., and seven species of Puccinia. — W. B.

LICHENS 



1245. Knight, H. H. The lichens of Minehead district. Trans. British Mycol. Soc. 7: 

 16-18. 1921. — A list is given of about 146 species of lichens collected in the vicinity of Mine- 

 head, Somersetshire, during the autumn foray of 1920. Three fungus parasites on lichens were 

 found. — W. B. McDougall. 



1246. Mereschkovsky, C. Diagnoses of some lichens. Ann. and Mag. Nat. Hist. 

 8: 246-290. Fig. 1-2. 1921. — The author gives Latin diagnoses of a large number of lichens 

 which he has previously described in Russian and French. In some cases the descriptions are 

 brief, the collections and notes having been left in Russia. Some corrections are made to 

 his preceding paper (see Bot. Absts. 8, Entry 479). — H. H. Clum. 



1247. Paulson, Robert. The sporulation of gonidia in the thallus of Evernia prunastri 

 Ach. Trans. British Mycol. Soc. 7:41-47. Pl.l. 1921.— "The gonidium does not multiply 

 vegetatively as a constituent of the lichen thallus, but the original protoplast of the mother 

 cell divides into 2, 4, 8, or 16 — sometimes more — distinctly separate wall-less masses. Each of 

 these masses rapidly secretes a cell-wall, develops a chloroplast and nucleus and, in a short 

 time, resembles exactly, in miniature, the mother cell as it appeared before it commenced to 

 sporulate. The mother cell-wall, either by becoming difluent or by bursting, sets free the 

 daughter cells." — W. B. McDougall. 



1248. Paulson, Robert. The microscopical structure of lichens. Jour. QuekettMicrosc. 

 Club 14:163-170. PI. 4, fid- i~^- 1920. — The gonidia of most lichens belong to a species of 

 Chlorella, the cells of which do not divide vegetatively but reproduce by sporulation within 

 the algal mother cell, much as in free Chlorella cells. "Penetration of living gonidia by hyphae 

 seldom, if ever, takes place." — L. B. Walker. 



1249. Wainio, E. a. Lichenes Insularum Philippinariim III. Ann. Acad. Sci. Fennicae 

 15: 1-368. 1921. — This is the 3rd and concluding paper of the series, the first 2 having been 

 published in the Philippine Jour. Sci. Bot. 4: 651-662. 1909, and 8: 99-137. 1913.— The 

 series is largely based on the material collected by the Bureau of Science [P. I.], supplemented 

 by some specimens secured by Elmer and Baker. Sixty-four genera containing 514 species, 

 besides many varieties and forms, are described in the present work, of which 11 genera and 

 364 species as well as a great many varieties, are offered as new to science. This makes a 

 total of 87 genera and 635 species listed by Wainio in his 3 papers on Philippine lichens. No 

 attempt has yet been made to collect rock lichens, which are very conspicuous in many local- 

 ities. Following is a list of the genera described, with the number of new species and total num- 

 ber of species described in each : Arthonia (Ach.) Wainio, 29 species (21 new) ; Aspidopyrenium 

 Wainio, 2 species (1 new); Asterothyrium Miill.-Arg., 4 species, allnew; Bacidia DeNotaris, 17 

 species, all new; Baeomyces (Pers.) Mass., 7 species (2 new); Biatorella De'Sota.ns, 2 s^pecies
