98 .1 Momxfraph of the Myxogastres. 



mella slender, about one-third the height of the sporangium, 

 capillitium rather dense, the main branches springing from the 

 apex of the columella which is sometimes expanded in a discoid 

 manner, branches stout, simple for half their length, then two or 

 three times dichotomous, axils ac^ite, secondary branches straight, 

 sometimes anastomosing laterally, tips colourless, the other 

 portions blackish ; stem elongated, straight or sub-flexuous, conical, 

 smooth, blackish-brown, filled with amorphous organic matter, 

 springing from a hypothallus ; spores globose, dingy purple, 

 coarsely spinulose, 15 — 17 /x diameter. 



Scotland (Moffat) ; Tasmania ; N. Zealand. 



On moss, wood, &c. ; gregarious, 2 mm. high. A very fine 

 species, remarkable for the elongated stem becoming usually 

 much incrassated downwards, and in the apex of the columella 

 being in some specimens expanded into a disc from the margin 

 of which the primary branches of the capillitium originate. 

 Both these features are characteristic of the genus Enerthenema, 

 and the present species forms a connecting link between the 

 last-named genus and Lamproderma. Agreeing with L. ecliinu- 

 lata in the large, spinulose spores ; differing in the long, straight 

 branches of the capillitium, and the stem being filled with 

 amorphous lumps of organic matter. 



Lamproderma Ellisiana, Cooke. 



Sporangia globose, stipitate, minutely rugulose, blackish- 

 purple, rather dull ; columella short ; capillitium originating 

 from apex of columella, threads blackish-purple, very slender, 

 equal throughout, repeatedly forking from the base, angles very 

 acute; stem coloured like the sporangium and twice as long, 

 slender above, becoming very thick downwards, and expanding 

 into a small, circular, brown hypothallus; spores in clusters of 

 5 — 7 ; when the spores break up the clusters are sub-angular 

 but soon become globose when free, pale lilac, minutely warted, 

 15 — 16 IX diameter.
