46 THE JOURNAL OF BOTANY 



3-5-septate, with a few longitudinal septa, 25-35 x 12-14 [x. 

 (Tab. 516, fig. 8.) 



On various leaves and stems, Edgbaston, Studley, &c. Barely 

 perceptible to the naked eye. The conidia are formed in a basi- 

 fugal manner, the youngest at the apex. 



173. Graphium Passerinii Sacc. Syll. Fung. iv. 613. 



Stems erect, black, shining, hair-like, subulate, smooth, 1- 

 IJ mm. high, formed of numerous slender compacted brown 

 septate hyphge, all parallel and gradually thinning out at the top, 

 not markedly free at the tips. Head of conidia grey, oblong - 

 cylindrical, forming about •§— |- of the height of the whole. Conidia 

 hyaline, 5 x 2| //., ovate-oblong, but somewhat acute at one end, 

 very numerous and apparently involved in mucus. 



On dried twigs of Bramble, Hunnington (Ws.), June. 



174. Stysanus Mandlii Mont. Ann. Sci. Nat. (1845), p. 365, 

 t. 14, f. 2 ; Sacc. Syll. Fung. iv. 623. 



Gregarious ; stems 1-1^ mm. high, 20-25 ft thick, neai;Jy 

 black, fibrous, slender and straight ; head elongate-cylindrical, 

 sometimes forked, greyish brown. Conidia in short chains, ovate 

 or ellipsoid, 3|~5 x 2-2| fx, pale brownish, diaphanous. 



On twigs of Gooseberry, Studley Castle, April. I should have 

 put it down as a Pachnocybe, if I had not seen the spores in 

 chains. It differs from the type in having paler spores. 



175. Stysanus cybosporus D. Sacc. Staz. Sper. Ital. xxxi. p. 80. 

 Coremia at first tuber cularioid, afterwards stilboid, gregarious, 



olive-coloured ; when young wart-like, 1 mm. broad, ^ mm. high, 

 composed of a dense mass of branched septate olive hyphae, 

 bearing a few conidia at their summits ; when older, taller and 

 looser, like a Stysanus, l-l^- mm. high, paler upwards, and nearly 

 as broad as the height. Hyphae of stalk compact and parallel, not 

 very closely septate, olive, 5 /a diam., repeatedly branched up- 

 wards ; branches paler, composed of cuboid joints which at length 

 separate from one another except for a narrow central isthmus, 

 and become rounded spores, 6 /x diam. The spores are very pale 

 olive, but clear, and retain for a long time traces of their mode of 

 origin, being square-shouldered, and minutely apiculate on two 

 opposite sides. 



Abundant on dead herbaceous stems, Cannon Hill Park, Bir- 

 mingham, July to November. 



176. Sphacelia Curreyana m. Hyphis dense intertextis, 

 albis, 2-2|- /x diam. ; sporophoris ramosis, ramis primo solitariis, 

 dein oppositis, denique verticillatis, irregularibus ; conidiis glo- 

 bosis, 3-5 IX, in apicibus ramorum, ut videtur, solitariis. 



In sclerotiis Sclerotiiiice Curreyance, in Junco, Sutton Park 

 (Wk.). The sclerotia were of a delicate pink inside, and during 

 the previous year the same tufts of rushes had produced a 

 plentiful crop of the Sclerotinia.
