with paraphysis, more highly magnified ; c. mass of sporidia surrounded 

 by gelatine, ditto ; d. immature sporidium, ditto ; e. mature sporidia, 

 •0025 inch long ; /. sporidium with shreds of epispore ; g. epispore, more 

 highly magnified. 



1090. A. Kerverni, Cr. Ann. d. Sc. Nat. ser. 4. vol. x. p. 193. 

 On old cow-dung. Bathford, C. E. Broome. 



Plate XVII. fig. 34. a. Ascus with sporidia in a young state, magnified ; 



b. ascus with paraphyses and sporidia when mature, more highly magnified; 



c. tip of ascus, ditto ; d. paraphysis with mature sporidia, ditto, '00l inch 

 long. The sporidia are dark violet when mature, and not reticulated. 

 When young, they nearly fill the ascus ; but, when mature, are confined to 

 a small space. When their proper envelope bursts, a number of minute 

 globular bodies escape, apparently of a different character from the coarser 

 ones which fill the space between the primary and secondary membranes 

 when they are immature, fig. c. 



1091. A. sexdecemsporus, Crouan, I.e. p. 195. 



On horse- and cow-dung. Hanham, near Bristol, C. E. 

 Broome. 



Plate XVII. fig. 35. a. Ascus, magnified ; b. paraphyses, ditto; c. spo- 

 ridia, "0006 inch long, more highly magnified. 



*A. saccharinus, B. & Curr., Berk. Outl. p. 374. 

 On old leather and rag. Chislehurst, F. Currey. 



Plate XVII. fig. 36. a. Ascus, magnified ; b. sporidia, *0008 inch long, 

 more highly magnified. 



1092. Actidium Hysterioides, Fr. 



On chips, under fir trees. St. George's Hill, Weybridge, 

 May 5, 1861, F. Currey. 



1093. Sphinctrina tigillaris, n. s. Stipite brevi, cylindrico; 

 capitulo elliptico ; sporidiis oblongis, uniseptatis. 



On an old Polyporus from a beam in King's Cliffe Church, 

 and on wood at Batheaston, C. E. Broome. 



Extremely minute, looking at first like a little Stilbum. It 

 gives off a few threads on the surface of the matrix. The stem 

 consists of little oblong cells. Sporidia 'OOOIS-'OOOS long. 



1094. Tuber excavatum, Vitt. 



Rudloe, Batheaston, Leigh Wood, &c, C. E. Broome. 



*Genea Mspidula, Berk. 



This was formerly referred to Genea papillosa, Vitt., of which 

 Tulasne thought it might be a variety, though he adopted the 

 name given above. Vittadini, however, on seeing specimens, 

 pronounced it to be perfectly distinct. 



1095. Xylaria voporaria, Berk. MS. ; Curr. /. c. figs. 17, 26. 

 This curious plant was sent from Cornwall, in the shape of a 



Sclerotium which abounded in a mushroom-bed, to the destruc- 

 tion of the mushrooms. One of the specimens, under the care 

 of Mr. Currey, developed the very curious species of which he 

 has given a figure.
