scarlet sporangia, the capillitium, however, is typical. 
Distribution. Abundant in temperate and tropical regions. 
A, CINEREA (Bull.) Pers. A few clusters of pale drab sporangia with 
typical papillose capillitium were found on dead wood, 
Distribution. Common in temperate and tropical regions. 
This interesting collection confirms on the whole the remarkable constancy 
of the specific characters of the Mycetozoa, and gives a further proof of the 
wide distribution of many of the species. A large number of Mycetozoa 
appear to thrive equally well in warm or cool climates, bat certain species 
may be considered especially characteristic of warmer regions. As examples 
of these in the present collection, Physarum roseum and Stemonites splendens 
may be mentioned ; on the other hand one notes the absence of any species 
of Trichia, a genus abundantly represented in temperate woods, but com- 
paratively rare in the tropics,
