182 THE .MVXOMVCETE.S OF PICTOU COUNTY. MOORE. 



3. Ceratiomyxa yorioides (Alb. & Schw.) Schroter. — In 

 tliis species the ])laite-]ike spor()])liores are connected together 

 after the manner (if a honeyednih, giving the fructification the 

 appearance nf a small, sessile, upturned polypoiTis. The plas- 

 n^.odinni is waterv white an;l after emerging for fructification 

 fcrnis a mucilaginous poroso layer extending oA'er a considerable 

 area. The sjinnis are similar to those of the preceding species. 



Found on decaying hendock blocks 



Lister in his monogTaph of the Mycetozoa includes both of 

 the foregoing species in Ceratiomyxa mucida Schroter. 



Myxogastres (Fries) Macbr. 



Myxomycetes in which the spores are developed in spor- 

 angia. The germinating spores produce amoeboid swarmers 

 which eveiitually lose their flagella and become amoeboid bodies. 

 They miilti])ly l)y division and, later, fuse to form plasmodia. 

 In the mature condition fruit bodies are formed consisting 

 chiefly of spore-; enclosed in a structureless limiting membrane, 

 the peridium, which may consist of one or two layers. In most 

 cases the sporangia contain in addition 1o the sporesi a structure 

 consisting of filameiU-^ or tnludes, of characteristic form, the 

 capillLtium. 



Order I. 



PHYSARACE^. 



Capillitimn present, generally containing lime deposits in 

 tlje form of amorphous granules which are aggregated in vesi- 

 c\ilar expansions of the ca])illitial threads forming the so-called 

 lime knots. Lime grannies also occur in connection with the 

 peridium and stipe. 



Tn the family Physarea^ the lime d<'j)0isits occur both in the 

 ])(iridium and in the capillitium which is intricate. In the 

 family Didymieae the capillitium is comparatively simple and 

 the lime deposits are confined to the peridium.
