In the following Schweinitzian species the fructification is un- 

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

 I-MII Fungi. 



Sphcerice Villosce. 



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 ffibes aureum, Bethlehem, Pa. 



1531. Sphceria intonsa, Schw. Gregarious, black, erumpent, 

 subhemispherical, apex obtuse, ostiolum indistinct. Perithecia small, 

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



On decorticated 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 very small, ovate, 

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

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

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

 The smallest of the tribe. 



On branches of Rubus Idceus, Bethlehem, Pa. 



1537. Sphceria viridiatra, Schw. Scattered or subcespitose. 

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

 M-arcely 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, Cke.
