1985. Rosen, H. R., and R. S. Kirby. A comparative morphological study of aecia of four 

 different rusts found upon barberries in North America. Phytopath. 9: 569-573. B pi., 1 fig. 

 1919. — This is a comparative study of the aecial stage of Puccinia graminis, P. oxalidis, 

 P. fendleri, and Aecidium butlerianum occurring on the various species of Berberis in North 

 America. — ■/. G. Dickson. 



1986. Searle, G. O. Some observations on Erysiphe Polygoni DC. Trans. British 

 Mycol. Soc. 6: 274-293. 1920. — ^Out of seventy-seven varieties of swedes, turnips, and rape 

 none were found immune to Erysiphe Polygoni though the swedes were attacked more vigor- 

 ously than the turnips. The form of Erysiphe Polygoni attacking Brassica campestris and 

 B. oleracea is a biologic form with the additional distinction that inoculations from B. cam- 

 pestris to B. oleracea invariably give "subinfections" as a result. "Subinfections" were 

 observed in the field on varieties of B. oleracea and were found to survive the winter and in some 

 cases to grow into full infections. Conidia were shown by inoculation experiments to be 

 viable. A probable method of over-wintering of the fungus on cultivated species of Bras- 

 sica is by means of "subinfections" on varieties of B. oleracea aided by persistent mycelium on 

 varieties of B. campestris. — W. B. McDougall. 



1987. Smith, A. Lorrain. A drain-blocking fungus. Trans. British Mycol. Soc. 6: 262- 

 263. 1920. — ■Fonies ulmarius was found in, and completely closing, a drain-pipe 30 feet below 

 ground. — W. B. McDougall. 



1988. Smith, A. Lorrain. Pimina parasitica Grove. Trans. British Mycol. Soc. 6: 295- 

 296. 1920. — Pimina parasitica Grove is identical generically if not specifically with Vro- 

 phiala mycophila Vuill. Vuillemin believes that Grove's genus should be discarded because 

 of its very imperfect description. If this contention is accepted, Grove's species becomes 

 Urophiala parasitica; if the genus Pimina is accepted then Vuillemin's species becomes 

 P. mycophila. — W. B. McDougall. 



1989. Stone, R. E. Upon the audibility of spore discharge in Helvella elastica (Bull.). 

 Trans. British Mycol. Soc. 6: 294. 1920. — 'The puff of spores from fruit-bodies of Helvella 

 elastica was found to be accompanied by a distinct hissing sound which could be heard at a 

 distance of five or six feet from a covered basket containing the fungi. — W. B. McDougall. 



1990. Stone, R. E. Upon the visibility of spore dissemination in Femes pinicola (Swartz.) 

 Fr. Trans. British Mycol. Soc. 6: 293. 1920.— By taking a position such that the fungus was 

 between the observer and the sun, clouds of spores were seen streaming from the under 

 side of a fruit-body of Fomes pinicola. — W. B. McDougall. 



1991. Wakefield, E. M. The Baslow foray. Trans. British Mycol. Soc. 6:239-247- 

 1920. — 'The twenty-third annual Fungus Foray, which was held at Baslow, Derbyshire, from 

 September 22 to September 27, 1919, is described and a complete list of the fungi gathered, 

 numbering 391 species, is given.— TF. B. McDougall.
