No. 104.] 53 



Leptosphaeria Kalmiae, n. sp. 



Perithecia subcfespitose, erumpent, .014 to .018 in. broad, sub- 

 hemisphaBrical, thick, black, the ostiola pertuse or slightly papillate; 

 asci cylindrical, .004 to .005 in. long, .0003 to .00035 broad; spores 

 nniseriate, oblong or subfusiform, triseptate, sometimes slightly con- 

 stricted at the middle septum, colored, .00065 to .U008 in. long, 

 .00025 to .0003 broad; parapbyses filiform. 



Dead stems of sheep laurel, Kalmia angustifolia. Adirondack 

 mountains. June. 



Generally there are two to four perithecia in a cluster, but some- 

 times they are single and occasionally laterally compressed. The 

 epidermis usually ruptures longitudinally. The species is related to 

 LeptosplKBria vagabunda. 



Zignoella diaphana, Sacc, 

 Decaying wcod. Adirondack mountains. June. 

 Our specimens have the perithecia depressed and smaller than in 

 the type. 



Pyrenophora relicina, Sacc. 

 Dead leaves of quack grass, Triticwn repeyis. West Albany and 

 Helderberg mountains. May. 



Cryptospora Tiliae, Tul. 

 Dead branches of basswood, Tilia Aynericcma. Helderberg moun- 

 tains. May. 



Hypocrea fungicola, Earst. 

 Decaying Polyporus. Caroga. July. The species was formerly 

 confused with H. ciirina, which it very closely resembles. 



Pleonectria Berolineusis, Sacc. 

 Dead stems of currant, Rihes rubrum. Albany. April.

 EEMARKS AND OBSEPtVATIONS. 



Ranunculus repens, L. 



A beautiful double flowered Ranunculus was found growing in a 

 wet place by the road side in the village of Bergen. Its creeping 

 stems and other characters connect it with R. rapens, and especially 

 with that form of it which was described by Dr. Beck as R. Clintonii. 

 "Whether the plant with its double flowers was a spontaneous develop- 

 ment or whether it had escaped from cultivation in some garden is not 

 known. 



Actaea alba, Bigel. 



A form with long slender pedicels was found at Karner growing 

 with A. rubra. The latter sometimes has thick pedicels, so that the 

 color of the fruit remains as the most reliable character for distin- 

 guishing these species.
