places where conservatories had been newly painted, and have had 

 it sent to me from other towns. These specimens, after being 

 examined microscopically, were put away in my herbarium. A 

 curious sequel followed. In May the iron bath, in a room about 

 twelve yards away from my study table, was newly painted with, 

 I suppose, the ordinary white bath-enamel. It happens, by good 

 fortune, that the bath is badly made, so that from a portion of the 

 lower surface (about half a square foot in area) the water escapes 

 very slowly. On this surface, and only on this, there appeared at 

 the end of May a number of pinkish or rosy-purple patches, 

 which beneath the microscope were seen to consist of mycelium, 

 and in June these were covered with the pycnidia of the Phoma. 

 The spores must have been carried accidentally to the bath-room, 

 and there found the requisites of growth — warmth, continual 

 moisture, and a newly painted surface. The mycelium grew 

 freely in the paint, and could be scraped off in large quantity. 



Uromyces Loti Blytt. Since writing the note on this 

 species (Journ. Bot. 1911, p. 367), I have received from Mr. 

 C. Crossland some plants of Lotus angustissimtis (collected in 

 1907 by Dr. C. C. Vigurs near Newquay, Cornwall), on which the 

 same Uromyces occurred. The teleutopores were, however, in 

 this case less strongly marked with the lines of warts : the 

 difficulty of seeing them may have been partly due to the age 

 of the specimens, since markings of this kind are often best seen 

 on fresh material. But it is no doubt also due to the variability of 

 the species in this respect ; Fischer remarks that he found striped 

 and warted teleutospores in the same sorus. In the spores from 

 L. angustissimus the markings were rather of the nature of short, 

 distinct, irregularly placed lines, while on L. corniculatus they 

 frequently formed long anastomosing ridges, though also some 

 were of the same character as in L. angustissimus. 



Hemileia Phaji Syd. Sir Frederick Moore has sent me from 

 the Botanic Gardens, Glasnevin, Dublin, some slides of a Uredine 

 on Phajus Wallichii; these were supposed to be the same as 

 Uredo Lynchii Plowr. on exotic Spiranthes at Kew Gardens 

 (British tjred. p. 259), but are seen on examination to be very 

 different. They show every character of a Hemileia, and are 

 no doubt identical with H. Phaji Syd. = Uredo Phaji Eaciborski. 

 Herr H. Sydow informs me that Hemileia Oncidii Griff, et Mau. 

 is a very similar species, and Sir Frederick says he has found a 

 similar Uredine to that which he sent me, on Oncidium varicosum, 

 0. Forbesii, as well as on Lycaste Skinneri and Epidendrum 

 vitellinum at the same Gardens. These may be the same, or 

 more probably distinct, species : only the uredo stage has been 

 found, and it appears at Glasnevin and elsewhere on freshly 

 imported plants, although it may spread to a small extent under 

 glass in this country. No doubt close examination would show 

 that several Uredines are imported on orchids in this way. 



In the specimens of H. Phaji, as shown by the slides, the 

 hyphae emerge from the stomata in little fascicles, becoming 

 somewhat clavate upwards, each surmounted by a subglobose and
