 their initial letters; P. for Plowden and Horderley Woods;

B. rubiginosa (Chev.) Rost. var. glohosa Lister. B. found 



on soil and dead wood as bright yellow plasmodium 

 which in a few days formed into sporangia. 



Physanun psittacinum Ditm. C. the sporangia are weathered; 

 this is usually a summer species.

 In this gathering the sporangia have stalks that are 

 white from included lime-granules; they closely 

 resemble Physarum Icucopus Link in general 

 appearance, but the character of the capillitium with 

 its abundant and rather straight hyaline threads 

 is that of P. nutans var. robustum. The specimen 

 was on dead wood; P. leucopus seems to be found 

 usually on dead leaves.
