The 'Myxomycetes of the Miami Valley, Ohio.

Growing on leaves, twigs, mosses, etc. Aethalium from 

 2 or 3 mm. to a centimeter or more in extent. I have a 

 specimen of Fuligo simulans Karsten, from Karsten himself ; 

 it is identical with my specimens of Fuligo ochracea Peck. 

 There could be no better representation of these specimens 

 made at that time than the description and figure of Fuligo 

 muscorum A. & S., in the Conspectus. 



5. FuiviGO cinerea Schw. Plasmodium milk - white, 

 changing to cinereous. Aethalium effused, variable in extent, 

 the surface rugulose and perforate, white, the hypothallus 

 thin or scarcely evident. Sporangia variously contracted and 

 grown together, forming a dense reticulum ; the walls a thin 

 pellucid membrane, with a thick white outer layer of granules 

 of lime. Capillitium a loose net-work of tubules, widely 

 expanded at the angles, the tubules for the most part filled 

 with lime, the nodules white, numerous, very large, angular, 

 and irregular, lobed and branched. Spores globose or oval, 

 minutely warted, dark violaceous, 10-15 x 10-12 mic. 



Growing on old leaves, herbaceous stems, etc. I find it 

 most abundantly about the horse barn, upon the old straw 

 and manure, sometimes running out onto the green herbage. 

 Aethalium from a few millimeters to several centimeters in 

 extent. Upon the testimony of Dr. Geo. A. Rex this is both 

 Enteridium cinereum and Lachnobolus ci?iereus of Schweinitz's 

 North American Fungi as represented in his herbarium. 

 It is Physarum ellipsosporum of Rostafinski. It is no doubt 

 also Aethaliopsis stercoriformis Zopf. 



IX. BADHAMIA Berk. Sporangia large, subglobose or 

 obovoid, sometimes depressed, substipitate or sessile; the 

 wall a thin membrane, with an outer layer of minute roundish 

 granules of lime, irregularly dehiscent. Stipe poorly devel- 

 oped, sometimes a mere strip of the hypothallus, often want- 

 ing. Capillitium of thick tubules, attached on all sides to 

 the wall of the sporangium, combined into a net-work of 

 large meshes, more or less expanded at the angles ; the 

 tubules containing minute roundish granules of lime through- 

 out their whole extent. Spores large, subglobose, dark viola- 

 ceous.
