Hob. On dead wood. — Glamis, Scotland (B.M. 100) ; Sweden 

 (B.M. 2787) ; Poland (Strassb. Herb.) ; near Kiel, Germany (B.M. 

 2788). 



4. L. flexuosa Pers. Syn. Fung., 197 (1801). Plas- 

 modium dull yellow or rose-coloured. Sporangia scattered, 

 pulvinate, depressed, or forming straight curved or branching 

 plasmodio carps 1 to 6 mm. long, either yellowish-brown and 

 glossy, or dark brown and opaque when an outer layer of 

 refuse matter is present ; sporangium-wall cartilaginous, 

 translucent, pale purplish-brown, usually more or less over- 

 laid with a thick mottled layer of olive-brown refuse matter, 

 dehiscing irregularly. Spores pale olive-brown, spinulose, 

 11 to 14 /a diam., yellowish-brown in mass. — Fr. Syst. Myc, iii. 

 197 ; Post. Mon., p. 218. L. variabilis Schrad. Nov. Gen. 

 PI., 18, pi. 6, figs. 5, 6 (1797) ? ; Macbr. N. Am. Slime- 

 Moulds, 146. L. Serpula Fr. Symb. Gast., 12 (1817) ? 

 L. alutacea Walk. Fl. Crvpt. Germ., 344 (1833). L. Schoenleinii 

 Johow Estud. Fl. Juan Fernandez, 195 (1896) ? Tubulina 

 flexuosa Poiret in Lam. Ency. Meth., viii. 131 (1808) ; Mass. 

 Mon., 37. 



PI. 148. — a. plasmodiocarp (England) ; 6. fragment of sporangium-wall and 

 spores ; c. spore. 



In the field this species somewhat resembles Enteridium olivaceum 

 var. liceoides, and also Dianema corticatum ; it differs from both in the 

 rough granular deposits on the sporangium-wall and in the yellowish- 

 brown colour of the spores. 



Hob. On dead coniferous wood. — Witley, Surrey (B.M. 2789) ; 

 Alderbury, Wilts (B.M. 2790) ; Savernake Forest, Wilts (B.M. 2791) ; 

 Yorks (B.M. 2792) ; Northumberland (B.M. 2794) ; Aberdeen (B.M. 

 2795) ; Ireland (B.M. 2793) ; Norway (B.M. 1441) ; Freiburg, Germany 

 (Strassb. Herb.) ; Holstein (B.M. 2796). 



5. L. biforis Morgan Myx. Miami Valley, 5, fig. 1 (1893). 

 Plasmodium ? Sporangia scattered, forming minute ellipsoid 

 or fusiform plasmodiocarps, 0*2 mm. long, 0-1 mm. broad, 

 glossy, yellow-brown, dehiscing along a central ridge or depres- 

 sion ; sporangium-wall membranous, minutely papillose, 

 almost colourless, with scanty superficial deposits of discharged 

 refuse matter. Spores somewhat ovoid, the wall thinner on 

 one side, 12 by 9 /x, almost colourless and smooth, pale 

 ochraceous in mass. — Macbr. N. Am. Slime-Moulds, 147 ; 

 Lister in Journ. Bot., xlii. 135. 



PI. 149.—?. six sporangia (Philadelphia) ; h. three sporangia ; i. fragment of 

 sporangium-wall and spores ; k. spore. 



This species is almost too small to be detected with the naked eye ; 

 when magnified one hundred times it bears considerable resemblance 

 to a date stone. 



Hob. On dead wood.— Philadelphia (B.M. 2061). 



The descriptions of Licea badia Fr. and L. incarnata Preuss are too 

 brief to be instructive ; the species should therefore be discarded.
