NEW OR NOTEWORTHY FUNGI.— Part IV. 



By W. B. Grove, M.A. 



(Plates 515, 516.) 



(Concluded from p. 18.) 



165. Trichosporium chartaceum Sacc. Syll. Fung. iv. 294. 

 Forming scattered, orbicular, black spots, 1-2 mm. diam. 



Hyphae vaguely branched, 4 /z diam. ; conidia numerous, pul- 

 verulent, brown or dark olive-brown, globose or elliptic, rather 

 rough, 4-6 X 4 /x. 



On damp brown paper, Birmingham, May. This differs from 

 the type only in the fact that the spores are not smooth, but 

 roughened and slightly angular, probably because they are more 

 mature. The fact that spores which are ultimately rough are 

 often quite smooth in their earlier stages has been the cause of 

 many mistakes. 



166. Scolecotrichum graminis Fckl. Sacc. Syll. Fung. iv. 348. 

 Tufts of conidiophores dense, black, spot-like, seated in long 



rows on elongated, arid, ochraceous spots. Hyphae erect, con- 

 tinuous, simple, nodulose, 100 x 6 /x, of a dusky but clear olive- 

 brown colour. Conidia of the same colour, obclavate, uniseptate, 

 averaging 40 x 9 /x. (Tab. 516, fig. 5.) 



On the under surface of living leaves of Phleum pratense, 

 Marston Green (Wk.), July. This might be considered identical 

 with S. sticticum B., except that it is seated on conspicuous 

 ochraceous spots, and appears to be decidedly parasitic. 



69. DiPLOcocciuM spicatum Grove, Journ. Bot. (1885), p. 167, 

 t. 257, f. 7 ; Sacc. Syll. Fung. iv. 374. 



This very rare fungus I have since found at Studley Castle, in 

 addition to the original locality at Sutton. The new specimens 

 revealed to me that (owing to a mistake in noting the magnifying 

 power used) I had given the size of the conidia {loc. cit) at half 

 their proper magnitude; they should be "20 x 10 /x." They are 

 at first obovate, not constricted, and pellucid but with a very dark 

 septum, afterwards assuming the mature form. 



167. Helminthosporium inconspicuum C. et E. Sacc. Syll. 

 Fung. iv. 411. 



Hyphae 250-300 x 10-11 ju, 6-8-septate, somewhat dark, paler 

 at the apex, where they are flexuous and nodulose. Conidia 

 oblong-lanceolate or nearly cylindrical, rounded at the ends, up to 

 120 fj. long, 15-16 /x thick, 5-septate, at length 8-9-septate, wall 

 always nearly diaphanous, pale olivaceous brown. (Tab. 516, 

 fig. 4.) 



On fading grass-leaves, Longdon Green, Lichfield (St.), Sep- 

 tember. I have already recorded (Journ. Bot. 1885, p. 168) a 

 variety of this species ; the specimens now described seem to be 

 nearly of the type, at any rate as figured by Peck (34th Report 

 p. 51, t. iii. f. 4-6). The chief mark of the species lies in the pale
