MYCETOZOA OF THE SOUTH MIDLANDS 165 
more extended areas, the following species are subject to these 
conditions :— 
Cerationyxa mucida. Tubulina fragiformis 
Amaurocheta atra. Dictydethalium plumbeum. 
Brefeldia maxima. Reticularia Lycoperdon, 
Lindbladia Tubulina. Lycogala miniatum, 
Enteridium olivaceum. L. flavo-fuscum. 
With the exception of Ceratiomyxa, all these form ethali 
he genera Trichia, Arcyria, and Cribraria are noteworthy in 
that they are not recorded for straw-heaps. Other s chatactitlatie 
of decaying straw, although not limited to such staasioul are :— 
Badhamia ovispora. Fuligo ellipsospora. 
Physarum straminipes. Didymium Trochus. 
P. didermoides. Spumaria alba var. dictyospora. 
P, didermoides var. lividum. 
These are sometimes found in great numbers, the straw being in 
places eomerate with the calcareous per a The we species 
apparently limited to these situation is D. Trochus. Badhamia 
ovispora has Seis recorded for the United States, also in association 
with straw-heaps. 
Our knowledge of the general distribution of the Mycetozoa is 
being gradually increased by the observations of travellers in remote 
regions; several lists from distant lands have appeared in this 
Journal in recent years, and 
those from the South Midlands m may not be without interest. The

Midlands. Of these, Pile 0 teas P, didermoides, pinion
