In the following Schweinitzian species the fructification is un- 

 known. The diagnoses are from Schweitz' Synopsis of North Ameri- 

 can Fungi. 



Sphcerice VUIohob. 



1513. Sphceria penicillata, Schw. — Perithecia scattered, but 

 forming extensive groups and arranged in subflexuous series, super- 

 ficial, the base firmly fixed to the epidermis, rarely fasciculate and sub- 

 confluent. Perithecia obovate-globose, flattened, densely villose, the 

 hairs towards the base shorter and dark green, from the middle up, 

 dense and longer, penicillate-divergent and very white, hiding the 

 minute, obtuse, black ostiola. Walls of the perithecia-black and thin, 

 sometimes collapsed, resembling a white-villose Peziza. 



On fallen twigs of Hibes aureum, Bethlehem, Pa. 



1631. Sphceria intonsa, Schw. — Gregarious, black, erumpent, 

 subhemispherical, apex obtuse, ostiolum indistinct. Perithecia small, 

 clothed with short, rigid hairs like a recently shaven beard. 



On decoi-ticated pickets of Robinia, Bethlehem, Pa. 



1532. Sphceria involuta, Schw. — Densely aggregated, loosely 

 attached. Perithecia smooth, subglobose, subpapillate, sometimes sub- 

 corrugated, dark brown, shining, entirely enveloped in a dense coat of 

 white wool which can be rubbed off; apex only slightly denuded. 



On old, decaying trunks, Bethlehem, Pa. Reminds one of Myri- 

 ococcum, (M. Everhartii)? 



1536. Sphceria ccespitulans, Schw. — Cespitulose-concrescent or 

 fasciculate in elongated-linear strips. Perithecia veiy small, ovate, 

 becoming irregular, acutely narrowed into the ostiolum, very black, 

 rugose, covered all over with minute, short, thick (almost tuberculi- 

 form) hairs, often irregularly collapsing, not cespitose, substance soft. 

 The smallest of the tribe. 



On branches oi Hubus Idceus, Bethlehem, Pa. 



1537. Sphceria viridiatra, Schw. — Scattered or subcespitose. 

 Perithecia minute, globose or ovate, carbonaceous, rugose, obtuse, 

 scarcely ostiolate, bare below, densely covered above with a short, 

 yellowish-green villose coat. Parasitic on various old compound 

 Sphcerias, Bethlehem, Pa. 



Reminds one of Calonectria chlorinella, Gee.
