40 Thirty-first Report on the State Museum. 



Milleria gen. nov. 



Peridium membranaceous, enclosing numerous minute sporangium-like 

 bodies bearing upon the surface a stratum of spores. 



This is a genus of Gasteromycetes, near Polysaccum. It is respectfully 

 dedicated to its discoverer. Mr. E. 8. Miller. 



Milleria herbatica Pk. 



Peridia oval or ovate-conical, subobtuse, firm, externally minutely warty 

 or mealy-furfuraceous, whitish, inclosing a mass of minute subglobose or 

 slightly angular sporangioles adhering together, black externally, pallid 

 within; spores superficial on the sporangioles, globose, colored, .0005-.00065' 

 in diameter. 



Panicles of Rhynchospora macrostachya. Wading River. Miller. 



This rare, but interesting fungus resembles in size and color the preceding 

 species, but its interior structure is wholly different. The sporangioles appear 

 to be composed of densely compacted or reticulated threads and cellular 

 matter. I have not been able to detect any investing membrane, the spores 

 appearing to rest directly upon the surface to which they give the black color. 

 The peridium does not appear to have been ruptured naturally in any of the 

 specimens. The cavity is only partly filled by the mass of sporangioles. 



Physarum psittacinum Dittm. 



Fallen leaves, decaying wood; bark and effete Hypoxylon. Adirondack 

 Mountains. Aug. 



Physarum ornatum Pk. 



Sporangia depressed or hemispherical, plane or slightly concave beneath, 

 greenish-cinereous, dotted with small yellow granules, the empty walls whit- 

 ish ; stem short, black or blackish-brown, generally longitudinally wrinkled 

 when dry ; columella none ; capillitium with numerous yellow knot-like 

 thickenings ; spores globose, smooth, violet-brown in the mass, .0004 / -.0005 / 

 in diameter. 



Decaying wood. Albany. Aug. 



Physarum atrorubrum PA\ 



Scattered or gregarious, stipitate; sporangia globose, even or somewhat 

 wrinkled, dark-red ; stem cylindrical, even, blackish or subconcolorous ; 

 capillitium when cleared of the spores whitish, sometimes with a slight pink- 

 ish tinge ; columella none ; spores globose, smooth, dark-brown in the mass, 

 dark-red when separated, .0003 -.00035' in diameter. 



Decaying wood. Adirondack Mountains. Aug. 



The plants are scarcely one line high. The capillitium is very delicate, 

 and when cleared of the spores, the knot-like thickenings are seen to be very 

 small and of a dark-red color, to which probably is due the pinkish tinge — 

 sometimes observed. A part only of the thickenings are filled with lime 

 granules. The dark-red granules of the sporangium walls are abundant, and 

 appear to form a continuous crust. 



Physarum in^equalis Pk. 



Sporangia sessile, subglobose or irregular, sometimes elongated and con- 

 fluent, red, abundantly dotted with minute scarlet granules ; capillitium
