New or Rare Microfungi. A. Lorrain Smith. 157 



from thestomata, unbranched, straight, cylindrical, non-septate, 

 slightly unequal-sided, about 18-22/x x 3-4'5/x; conidia, one or 

 two at the tips of the conidiophorcs, cylindiical, slightly pointed, 

 2-celled, colourless, 8-30/^ x 2-3 /u. 



On leaves of Lysiniachia Nummularia, Lochwinnoch, Ren- 

 frewshire; D. A. Boyd, July -1918. 



The spores are non-septate for a considerable time.

 p. 19; Cotton in Kew Bull. 1918, p. 18, fig. i. 

 On leaves and petioles of parsnip in Worcs., Glos. and Cambs. 



Daciylella cUipsospora Grove in Journ. Bot. xxiv. p. 200 (pi. 266, 

 fig. 9), 1S86. 

 A mould somewhat similar to this species was collected on 

 dead wood during the Selby Foray. The stalks are longer and 

 narrower, 130-230 yu, x 2-3 /x, and the spores are narrower, 

 measuring about 40 /x x 10-12 /x ; but the differences do not seem 

 to be specific and Grove's drawings even more truly represent 

 the Selby fungus than do his measurements. 



Torula convoluta Harz, in Bull. Soc. Imp. Nat. Moskow (separ- 

 ate), p. 47 (pi. I, fig. 6), 1871. 



Mycelium creeping, richly branched, septate; conidiophorcs 

 upright, very short, branched or unbranched, septate, terminat- 

 ing in long chains which roll up at the ends; conidia globose, 

 black, transparent, 2-5-3 /x i^ diam. 



On decaying and dry potatoes, also on decaying leaves. Found 

 by F. T. Brooks on potatoes in the Isle of Wight, summer, 1918. 



Cercosporella Pastinacac Karst. in Hedwigia, xxiii, p. 63, 1884; 

 Cotton in Kew Bull. 1918, p. 19, fig. 2. 

 On leaves and petioles of parsnip in Worcs., Glos. and Cambs. 



Dendryphium curtmn B. da Br. Collected at Parlington Park, 

 Selby, Yorkshire. 

 The fungus developed on branches kept under observation. 

 It agrees with the above species in every respect except in the 

 spores which in the vSelby specimen are catenulate, but this is 

 probably due to the very sheltered laboratory conditions. 



Cercospora Myrti Erikss., in Bidr. till Kanned. odl. vaxt sjuk- 

 domar, Stockholm, p. 79, 1885. 



Leaf spots amphigenous, roundish, red-purple. Tufts mostly 

 hypophyllous, the conidiophorcs in groups ; conidia gradually 

 tapering upwards, bent, 3-6 septate, 60-ioo/x x 2-4/x, brown. 



On the leaves of cultivated myrtle. West Kilbride, Ayrshire, 

 Sept. 1918. Comm. D. A. Boyd.
