Ibadan and Agege, on dead wood and palm-fibre, also on herbaceous 

 plants. This variety appears to be common in the tropics. 



C. LONGA Peck. Ibadan. Mr. Farquharson writes: "The 

 white Plasmodium had, I think, emerged in a large mass from 

 an oil palm lying on the ground, and had slid or dripped — such 

 was its appearance — on to the neighbouring plants, where the 

 sporangia formed masses six or seven inches across weighing the 

 leaves down ; some of the sporangia must have been at least an 

 inch long. I tried to get a photograph to convey some impression 

 of the size and appearance, but the sporangia were extremely soft, 

 and photography in a draughty bungalow was a matter of extreme 

 difficulty." The photograph conveys a far better idea of the 

 hanging masses of sporangia as they grew than can be given by 

 collected specimens, however carefully they may be packed. The 

 sporangia are very slender ; towards the apex the capillitium does 

 not form a netw^ork, but is reduced to a spiral or to whorls of stiff 

 branches spreading from the flexuose columella, and dividing into 

 a few spine-like branchlets. 



Lamproderma arcyrionema Eost. Abundant at Agege on 

 dead wood ; in one large growth the silvery sporangia are scattered 

 over an area fourteen inches long by two to tliree inches wide. 



DicTYDiUM cancellatum (Batsch) Macbr., yhy. fuscum Lister 

 Fairly common at Ibadan and at Agege, on dead wood forming 

 large developments. The brow^n membranous cup at the base of 

 the sporangium is usually small and may be absent. 



Cribraria intricata Schrad., var. dictydioides Lister. Iba- 

 dan ; a single large and perfect growth w^as found on dead wood. 



TuBiFERA ferruginosa Gmel. Ibadan, found inside a hollow 

 palm stem. When moist the masses of sporangia w^ere reddish- 

 copper coloured with a metallic lustre. 



DicTYDiiETHALiUM PLUMBEUM (Schum.) Eost. Ibadan; 

 eleven small pinkish ochre or drab sethalia are sent ; the minute 

 component sporangia are 0-2 to 0-3 mm. high, 0-09 mm. broad. 



Eeticularia Lycoperdon Bull. Several a^thalia w^ere found 

 at Agege on a decaying stump of oil palm : the largest was 

 1-5 inches across. 



Lycogala epidendrum (L.) Fries. Abundant at Ibadan and 

 Agege on dead wood. 



Hemitrichia Vesparium (Batsch) Macbr. Ibadan ; found 

 once in a very moist hollow- stump of an oil palm : small clusters 

 of typical purplish-red sporangia are scattered over the wood and 

 enclose coils of very spinose capillitium. 



H. CLAVATA (Pers.) Eost. " Common on palms and other 

 stumps; emerging as coral-pink plasmodium, and becoming 

 maroon-red then brown as the sporangia matured." 



H. Serpula (Scop.) Eost. Common at Ibadan on dead bark ; 

 the orange-yellow net-like plasmodiocarps often formed con- 

 spicuous objects covering several square inches. Mr. Farquharson 

 whites that a very fine plasmodium of this species emerged from 

 some fragments of dead wood w4iich he had kept moist in a glass 

 dish, and matured normally.
