96 Thirty-eighth Report on the State Museum. 



Appendicularia entomophila, n. sp. 



Perithecia oval, brown, .0045 to .0055 in. long, .0035 to .004 broad, 

 tapering abruptly above into a long, pale, somewhat pointed, straight or 

 slightly curved rostrum .008 to .0095 in. long and about one-tenth as 

 broad, supported below by a pale pedicel .012 to .013 in. long, about 

 one-tenth as broad ; pedicel two-septate, slightly thickened at the apex 

 and bearing on one side, at the base of the perithecium, an oblong ap- 

 pendage about .0016 in. long; spores narrowly fusiform, pointed at 

 each end, septate near the middle, colorless, .0012 to .0018 in. long, 

 about one-tenth as broad, escaping at the apex of the rostrum.

 March. Rev. J. L. Zabrishie. 



Specimens of this minute but interesting fungus, beautifully mounted 

 on microscopic slides,- were sent me by Mr. Zabriskie, who discovered 

 them on small flies in his cellar in March last. He writes that they ap- 

 peared during the first warm days of Spring, but disappeared upon the 

 return of colder weather a few days later. The fungus grows upon al- 

 most any part of the body, the head, thorax, abdominal rings and occa- 

 sionally on the costse of the wings, but most frequently on the legs. 

 Attached to one leg sent me are seven well-developed specimens of the 

 fungus and one or two imperfect ones. The whole fungus is about one- 

 fortieth of an inch long, or less than one-third of a line. It would not, 

 therefore, be readily seen by the untrained naked eye of an observer. 

 The perithecium, which is of a beautiful amber-brown color in the 

 mounted specimens, appears like an enlargement of the central part of 

 the fungus, its long rostrum or beak extending above it nearly as far as 

 its pedicel does below it. The pedicel has one septum a little below the 

 perithecium and another a little below the middle. At the apex it is 

 slightly thickened, which gives it a somewhat clavate -shape, and this 

 enlargement is obscurely marked by short transverse and longitudinal 

 septa or wrinkles. On one side, at the base of the perithecium is the 

 singular erect appendage, the office of which is involved in obscurity. 

 It is even and glabrous on the side next the perithecium, but elsewhere 

 it is roughened by short ascending projections or serrations. 



The affinities of the fungus are not clear. The non-ascigerous peri- 

 thecium, the long, slender rostrum and the free spores oozing out at its 

 apex indicate a relationship to species of Sphaeronema (a genus of im- 

 perfect fungi), but the delicate texture and filamentous pedicel are very 

 unlike any thing in that genus. Possibly its true relationship may be 

 with the Saprolegniae, but for our present purpose it is placed with the 

 imperfect fungi.

Dead stems of Viburnum nudum. Caroga. July. 

 This is Sphceronema hystricinum, Ellis, and is possibly a condition 

 of some species of Cenangium. 



Sphaerographium lantanoidis, n. sp. 



Perithecia minute, terete or subcorneal, truncate at the apex, black ; 

 spores subfiliform, curved or flexuous, slightly narrowed toward each
