2 Notes on fungi 



Asterina rubicola E. & E. 



On living leaves of Rub us canadensis L. Albany. 

 H. D. House, July 25, 1915. 



Aulographum subconfluens Peck 

 (28th Rep't, p. 70. 1876. Sacc. Syll. II, p. 729) 

 The host plant given for this species by Professor Peck is " dead 

 herbaceous stems," but an examination of the type specimens shows 

 that the host is Thalictrum. Professor Peck obtained a later col- 

 lection of this species near North Elba upon a host which he defi- 

 nitely identified as Thalictrum. 



Barlaea lacunosa E. & E. 



(Proc. Acad. Phil. 1894, p. 347. Sacc. Syll. XL, p. 396) 

 The only host given for this in the original description is " on 

 bark." The specimen in the herbarium of the New York State 

 Museum, from Waghorne, and presumably a duplicate of the type 

 collection is on bark and dead twigs of Abies balsamea. 



Ascochyta clematidina Thiim. 

 (See figure 1) 

 During the past two seasons this fungus, parasitic on the leaves 

 of Clematis, has been noted with great frequency, causing a serious 

 disfiguration and frequent death of leaves of the Virgin's-bower 

 (Clematis virginiana) both wild and cultivated. Speci- 

 mens of diseased leaves were collected in the counties of Albany, 

 Rensselaer, Greene, Oneida, Madison and Onondaga. I assume 

 that the disease, at least as a common parasite of the Clematis, is of 

 recent appearance in this State, although it has been occasionally 

 mentioned in literature as the cause of a serious leaf disease of 

 cultivated Clematis, because there are no specimens in the state 

 herbarium collected by Doctor Peck, who would not have over- 

 looked it if it had been common in past years. It also appears to 

 have been collected by J. M. Macoun, at Ottaw r a, Canada, in 1897. 



Calyptospora columnaris (A. & S.) Kuhn. 

 Sylvan Beach, Oneida county. On stems of Vaccinium 

 corymbosum Linn. H. D. House, May 13, 1915.
