156. Fusoma tenue m. Tenuissime effusum, oculo inarmato 

 baud visibile. Conidiis clavato-fusiformibus, 3-7-septatis, baud 

 constrictis (septis tenuibus), byalinis, 25-45 x 7^-8 /x. (Tab. 515, 

 fig. 9.) 



In caule emortuo Angelicce, Alvecburch (Ws.), Jun. The 

 youngest conidia seen were 3-septate, 25 /x long ; then the middle 

 cells are again divided, making them 5-septate; finally the process 

 is repeated by the two central loculi, and thus the spore, when 

 45 fi long, is 7-septate. 



TRIDENTAEIA Preuss, emend. Hyphae in conidia in for- 



mam tridentis connata abeuntes. Conidia oblonga v. clavata. 



157. Tridentaria setigera m. Tenuissime effusa, alba, baud 

 conspicua. Hyphis trilocularibus, deorum attenuatis, sursum 

 flabelli ad instar expansis applanatisque ; conidiis tribus in basi 

 palmatifida connatis, 10-15 x 3-5 /x, oblongis, 1-3-septatis, hya- 

 linis, apice rotundatis v. subacutatis, in utroque latere cum seta 

 acuta hyalina septata consociatis. (Tab. 515, fig. 10.) 



In caule emortuo Angelicce sylvestris, sociis Fusomate tenui et 

 MolUsia atrata, Alvecburch (Ws.), Jun. 



This species may well be placed in the genus incompletely 

 described by Preuss (Lmncea, 1852, p. 74), if a few slight altera- 

 tions are made. 



158. Hormiscium callisporum m. = Torula (?) callisioora 

 Speg. Sacc. Syll. Fung. iv. 262. 



From a creeping mycelium arise short erect chains of conidia 

 (or joints), forming a dusky effused patch. Chains up to 80 /x 

 long, fusiform, straight or slightly curved, consisting of 4-10 joints. 

 Joints 6-10 /x broad, nearly spherical, at the ends pale olive and 

 smooth, in the middle of the complete chains (of 10 conidia) they 

 are larger, darker, and minutely but distinctly asperulate. A few 

 of the ripest conidia are rough and completely opaque. (Tab. 516, 



fig. 1.) 



On stems of an UmbeUifer, Longdon Green (St.), September. 

 This seems to be identical with Spegazzini's species, though not 

 quite so completely evolved. The joints separate from one another 

 with difficulty. 



159. Stachybotrys lobulata Berk. Sacc. Syll. Fung. iv. 269 

 Mass. Fung. Fl. iii. 368. 



Sterile hyphge creeping over the matrix, delicate, colourless. 

 Fertile erect, 5-6 /x diam., alternately cymosely branched, brown, 

 darker upwards, when perfect minutely asperate. At the apex is 

 a crown of 5-7 clavate sporophores, each 15 x 5 /x, obtuse, smooth, 

 and often paler than the apex of the hypha, from which the 

 whole crown easily separates. Heads of conidia varying in size 

 according to age, spherical, deep black, held together by a little 

 mucus. Conidia elhptic, pale at first and smooth, with two very 

 small guttulae ; then darker olive, with larger guttulae, but still
