On the dung of dogs and cats in wet weather. Very common. — 

 The sporidia in this species are by no means constantly globose ; they 

 are figured as elliptic by Dr. Greville and such I find them. Head at 

 first white, then bright yellow, then yellow-brown, at length black. 

 Occasionally the colour is not so bright and in the last stage the heads 

 are scarcely black. Flocci at first erect, soon leaning in every direc- 

 tion. 



4. M. fusiger, Lk. (Spindle-seeded Mould) ; byssoid, fertile 

 flocci simple, peridiola globose hyaline, at length black, sporidia 

 fusiform. Lk. Sp. \.p. 93. Fr. Syst. 3Iyc. v. S. p. 321. 



On the gills of decaying Agarics. East INIorden, Dors,, Rev. 3L J. 

 BerJieley. — Flocci septate, filled internally with distinct granules, 

 thinly scattered, divergent, springing from the branched mycelium in 

 such a manner that several of the sterile ^occ? unite to give off the 

 simple sporidiferous thread. Sporidia exactly fusiform. 



5. 31. clavdtus, Lk. (clavate 3Iould) ; byssoid, fertile flocci 

 simple penetrating the globose peridiola by their clavate apices, 

 sporidia globose. Lk. Sp. 1. p. 92. Fr. Syst. Myc. 321. 



On rotten pears. Winter. Apethorpe, Norths. Itev. 31. J. Berkeley. 

 — Heads at first white, tiien brown, at length black, fertile flocci not 

 septate, indistinctly granular within. Sporidia minute. 



6. 31. amethysteus, Berk. (Amethyst Mould) ; fertile flocci 

 simple, peridiola white, then pale- yellow, then crystalline and 

 pure violet, at length violet-black or brownish, sporidia glo- 

 bose filled with globose sporidiola dull violet. 



On rotting pears with the foregoing — Fertile flocci about ^ of an 

 inch high, four times as thick as in M. clavatus, filled with distinct gran- 

 ules; heads depresso-globose, sometimes collapsing slightly and nodding; 

 spo?-idia rather large, containing globose sporidiola, which easily 

 separate. 3Iycelium thick, expanded, pure white, closely interwoven. 



7. M. delicdtidus, Berk, (mimde yellow-headed 3Iould) ; fertile 

 flocci simple abbreviated of the same thickness as those of the 

 mycelium, peridiola globose pale-yellow, sporidia globose. 



On rotting gourds. Autumn. Apethorpe, Norths. Rev. M. J. 

 Berkeley. — So small as to be scarcely perceptible by the naked eye, 

 forming a velvety stratum saturated with the juice of the matrix, 

 Head at first white, then very pale yellow, sometimes apparently spring- 

 ing immediately from the branched septate mycelium and decumbent.
