NOTES ON THE MYCETOZOA OF LINN^US 161 



under the fungus genera Clathrus, Lycoperdon, and Mucor. 

 Although Linne's own descriptions here quoted are usually very- 

 short, they are in most cases accompanied by references to 

 descriptions and illustrations of previous authors which permit 

 the species to be identified. 



The species are Clathrus denudatus, C. nudus, C. recutitus, 

 Lycoperdon radiatum, L. epidendrum, Mucor septicus, and M. 

 Embolics. 



" Clathrus denudatus. C. stipitatus, capitulo oblongo 

 valvato. C. pediculatus purpureas capite oblongo Guett. Stamp, 

 p. 17. Clathroides purpureum pediculo donatum Mich. Gen. 

 p. 214, t. 94, fig. 1. Habitat in Europa australiori." The 

 reference to Micheli's description and illustration makes it clear 

 that this is the species now called Arcyria denudata Sheldon 

 (syn. A. punicea Persoon). 



" Clathrus nudus. C. stipitatus, capitulo oblongo axi longitu- 

 dinale adnato. Fl. Suec. n. 1264. Clatliroidastrum Mich. Gen. 

 p. 214. Habitat in Italiae lignis putridis." This brief description, 

 and the diagrammatic figures of Clatliroidastrum in Micheli's 

 Nov. Plant. Gen. tab. 94, may apply to almost any species of the 

 genus Stemonitis. Eostafinski follows Fries in giving Clathrus 

 nudus as a synonym for Stemonitis fusca Both. 



" Clathrus recutitus. C. stipitatus capitulo globoso, glande 

 ovali. Fl. Suec. n. 1264. Habitat in Suecicae truncis arborum." 

 In the thirteenth edition of Linne's Sy sterna Natures , edited by 

 G. F. Gmelin (1791), this species is placed in the genus Stemonitis, 

 with the following description : — " Stemonitis albida fills ovatis, 

 stipite brevi." On the strength apparently of Gmelin's definition 

 Fries gives Clathrus recutitus as a synonym for Arcyria cinerea 

 (Bull.) Pers. (Syst. Myc. iii. 180). 



11 Lycoperdon radiatum. L. disco hemispherico, radiato, 

 colorato. Habitat in Suecicae lignis Abietinis putridis, ad praedium 

 nostrum Saefja, ubi lectus 1760 a Filio. Magnitudine dimidii 

 fructus Coriandri. Discus subglobosus, fuscus, elastice dehiscens, 

 expellensque cum avolante polline lanam bombycinum, tumes- 

 centem, fuscum, rariorem adhaerentem. Limbus campaniformis, 

 niveus, sectus fere ad basin in partes 12 aequales, disco paulo 

 longiores, basi integri ovali cingente discum." There is evidence 

 to prove that the type here referred to is in the Linnean 

 Herbarium (see below). The species is Diderma radiatum 

 Lister. 



" Lycoperdon epidendrum. L. cortice farinaque purpurea. 

 Fl. Suec. n. 1114. L. epidendron miniatum pulverem fundens 

 Buxb. Hal. p. 203. L. sanguinewn sphcericum 1 Buxb. cent. 5, 

 p. 15, t. 29, f. 2. Habitat in Lignis parietis antiquis." This 

 species is undoubtedly Lycogala epidendrum Fries. 



" Mucor septicus. M. unctuosus flavus. Fl. Suec. n. 1117 ; 

 1285. Mucilago flava ramosissima mollis Hall. helv. 5. Spongia 

 fugax mollis flava amcena March. Act. 1727, p. 472. Habitat^ in 

 vaporariis deservientibus visibili incremento, maturus semina
