114 ENDOSPOREJ5. [STEMONITIS. 



a large series of specimens of this group there is a general character 

 which runs through them all in the constant type of the spores and 

 in the smooth purple-brown capillitium, which points to the conclusion 

 that however widely the size of the mesh of the surface-net may vary, 

 they are all forms of one species.

3. S. herbatica Peck, in Rep. N. York Mus., xxvi.,p. 75 (1874). 

 Plasmodiurn ? Sporangia cylindrical, in densely fasciculated 

 clusters, 5 to 7 mm. high, red-brown. Stalk 0'8 mm. high, 

 arising from a membranous hypothallus. Capillitium of dark 

 brown threads, springing from the columella and forming a very 

 loose network, uniting at the surface into a net with rounded 

 meshes, 7 to 17 /A diam. Spores pale reddish-purple, minutely 

 spinulose, 6 to 9 /x diam. Mass., Mon., p. 87.

The above description is made from Peck's type, kindly furnished 

 by "Dr. Rex. The species is allied to S. ferruginea and to S. splendens, 

 having the capillitium, and the habit of fruiting on herbaceous stems, 

 of the former, and the purplish spores of the latter. It holds an 

 intermediate position, different gatherings showing a tendency towards 

 one or the other of its allies ; but it is a useful centre under which to 

 place forms possessing a distinct general character which were difficult 

 to locate before Peck gave them a specific rank. It does not appear 

 in the collections as a British species, and European gatherings are not 

 frequent. The specimen figured from Java was given by Rostafinski 

 as a type of S. fusca, from which it is distinguished by the nearly 

 smooth spores and wandering habit of the plasmodium. Peck's type is 

 nearly identical with the Java specimen (see PI. XLIII., B., c and <7.).

4. S. ferruginea Ehrenb., Sylv. Myc. Berol., p. 25 (1818). 

 Plasmodium citron-yellow, in rotten wood, usually creeping from 

 the place of emergence, arid maturing on surrounding herbage. 

 Total height 5 to 7 mm. Sporangia cylindrical, obtuse, in 

 closely fasciculate clusters, stipitate or nearly sessile, cinnamon- 

 brown. Stalk black, 0'5 to 1'5 mm. high. Columella often 

 reaching the apex of the sporangium and expanding as a funnel- 

 shaped membranous cap, or ceasing far below the summit,
