1. Ceathrus denudatus — i. Clathroides of Micheli. 



2. Ceathrus NUDUs = Clathroidastrum of Micheli. 



3. Lycoperdon epidendrum— -Lycoperdon epidendron, 

 miniatum pulverem fundens. Btixbaum, En. PL Hal., 1 721 . 



4. Mucor embolus — 2. Embolus of Haller, 1742. 



In the second edition of the Flora Suecica (1755) he enume- 

 rated — 



5. Ceathrus recutitus. 



6. Mucor SEPTicus = Spongia fugax, etc., of Marchand: 



In the second edition of the Species Plantarum (1763) — 



7. Lycoperdon radiatum. 



Several species of Myxomycetes were described by Hall- 

 er in the Enumeratio (1742), and in the Historia (1768), but 

 as he did not accept the binomial nomenclature of Linnaeus, 

 these species appear with the names of later authors ap- 

 pended. Haller created the genera Embolus, Sphaero- 

 cephalus (1742) and Fuligo, Trichia (1768). 



John Hill, in "A History of Plants" ( 1 75 1) , proposed the 

 name Arcyria for the Clathroides and Clathroidastrum of 

 Micheli and the name Physarum to include Mucor, Lycogala 

 and Mucilago of the same author. Gleditseh (1753) substi- 

 tuted Stemonitis for the Clathroidastrum of Micheli. 



The additional species of the Myxomycetes contributed by 

 the writers succeeding Linnaeus down to the time of Persoon 

 may be enumerated as follows — 



Retzius, Act. Holm, 1769. 



8 — 9. Ceathrus ramosus. a. aureus, b. ricfus. 



10. Lycoperdon aggregatum = 3. Clathroides flaves- 

 cens, etc. Haller, En. Stirp, 1742. 



11. Lycoperdon stipitatum. 

 Scopoli. Flor. Carn, 1772. 



12. Eeveea infundibueiformis— Fungoides minimum 

 infundibuli forma, etc. Micheli. N. P. G., 1729. 



13. Mucor serpuea. 

 Scopoli. Ann. Hist. Nat., 177—. 



14. Mucor eycoperdoides.
