I am not certain whether the white filaments mentioned above 



properly belong to the plant. 



Plate VIII. fig. 10. a, Macrotporium tarcinula, nat. size; (>, white fila- 

 ments and infant sporidia; c, Bporidia from a patch in which the down has 

 vanished; d, same, more highly magnified ; e, perfect Bporidia ;/) same, 

 move highly magnified. 



1l'(>. Aspergillus niter nut us, n. s. On damp paper, King's 

 Clitic. Grey black. Forming little orbicular patches. Ex- 

 tremely minute, scarcely to be distinguished without a lens. 

 Mycelium thin, decumbent ; fertile flocci articulate, erect, or 

 subdecumbent, branched alternately in a zigzag manner ; 

 each branch terminated by a slightly swollen receptacle which 

 is studded with oblong subtruncate sporidia. The mode of 

 branching is as it were annotinous, the same as that of Asco- 

 tricha chart arum. The habit is that of Sporocybe, but in struc- 

 ture it agrees with Aspergillus. 



Plate VIII. fig. 11. a, Aspergillus alternatus, nat. size ; b, a portion mag- 

 nified ; c, the termination of one of the branches with its head of sporidia ; 

 d, sporidia. 



12/. Botrytis citrina, n. s. On dead branches of cherry 

 lying upon the ground, King's Cliffe. Summer. Forming 

 thin delicate mucedinous patches, about an inch across. My- 

 celium nearly white, as indeed is the whole plant at first. 

 Fertile flocci erect, articulated, branched; branches subcymose, 

 lemon-coloured, as well as the obovate spores. 



Plate VIII. fig. 12. a, a portion of the plant ; b, upper part of one of the 

 fertile flocci more highly magnified. 



128. Botrytis curta, Berk. Brit. Fung. Fasc. 3. n. 209. On 

 Anemone nemorosa, King's Cliffe. Distinguished from Bo- 

 trytis parasitica, which comprises many distinct forms by its 

 simple denticulate, not branched or scarcely branched threads. 

 Extremely minute, at length grey brown ; flocci simple, ab- 

 breviated, their tips denticulate ; spores oval. 



Plate VIII. fig. 13. Flocci and spores highly magnified. 



129. Penicillium fasciculatum, Sommerf. Fr. 1. c. p. 407; 

 Berk. Brit. Fung. Fasc. 3. n. 210. On various dead herba- 

 ceous plants, generally springing from Sclerotium durum, 

 King's Cliffe, &c.
