THE MYXOMYCETES OF PICTOU COUNTY. MOORE. 185 



Genus, Tilmadoche (Fries) Host. 



In this genus the eapillitial filaments regularly branch 

 dichotomously, anastomose sparingly and terminate in delicate 

 free ends. The lime knots are small and fusiform. In all tiie 

 species the sporangia are distinct. 



8. Tilmadoche alba (Bull) Macbr. Sporangia grey or 

 white, spherical, stipitate, nodding, about .4 mm in diameter. 

 Peridium with crowded clusters of included white lime granules. 

 Stipe short and stout, about equal to the diameter of the spor- 

 angium or slightly exceeding it, subulate, dark in color below, 

 pale towards the upper part. The capillitial threads arise from 

 the base of the sporangium, branch dichotomously with flattened 

 expansions at the axils, and are provided with numerous small, 

 white lime knots. Spores violet tinted by transmitted light, 

 smooth, about 8ft in diameter. 



On decaying conifers, fairly common. 



9. Tilmadoche viridis (Bull) Saccardo. Sporangia scat- 

 tered, yellow or orange in color with a cast of green, stipitate, 

 spherical, nodding. Peridium with numerous included lime 

 granules. Stipe about l mm long, tapering upward,, furrowed, 

 twisted at the top; dark below from refuse material becoming 

 pale above. Sporangia about .5 mm in diameter. Capillitium 

 abundant persisting as a tuft after the dispersal of the spores. 

 Lime knots orange colored and fusiform, generally small. The 

 capillitial threads are delicate, branch frequently and are not 

 expanded at the axils. Spores violet colored by transmitted 

 light, nearly smooth, 9 10 ft in diameter. 



On 'decaying Fagus ferruginea. 



Genus, Leocarpus (Link) Eost. 



Peridium double, the outer thick, calcareous, brittle and 

 shining. Capillitium consists partly of hyaline threads and 

 partly of broad anastomosing tubules filled with colored lime 

 granules.
