116 Forty- SIXTH Report on the State Museum. 



Anthostoma Ontariensis E. d E. 



Dead branches of willow, Salix discolor. Karner. May. 

 In our specimens the stroma is eutypoid rather than valsoid 

 and the spores are a little broader than in the type. 



Stigmatea Geranii Fr. 



Living and languishing leaves of Carolinian cranesbill, Ger- 

 anium Caroliniamiin, Brownviile. June. 



Massariella Xanthoxyli n. sp. 



Perithecia small, .02 to 028 in. broad, immersed in the bark, 

 scattered or subseriate, slightly elevating and at length piercing 

 the epidermis ; asci 8-spored ; spores crowded or biseriate, at first 

 colorless, then colored, uniseptate, quadrinucleate, oozing out and 

 forming a conical mass, then distinctly uniseptate but. not 

 nucleate, .0024 to .0027 in. long, .0005 to .0007 broad. 



Dead stems and branches of prickly ash, Xanthoxylum Ameri- 

 canum. Mechanicville. May. 



In 3^oung specimens the bark has a much smoother and cleaner 

 appearance than in old ones. In these it is roughened and stained 

 by the heaps of ejected spores. The young spores have a strong 

 resemblance to those of Massaria vomitoria, but the perithecia 

 are much smaller than in that species and the uniseptate mature 

 spores are quite distinct. 



Ophiobolus subolivaceus n. sp. 



Perithecia numerous, depressed, .012 to .014 in. broad, at first 

 covered by the epidermis, then superficial, black ; asci clavate or 

 cylindrical ; spores slightly curved, gradually narrowed toward 

 each end, yellowish -brown by transmitted light, five-septate, .002 

 to .0025 in. long, .00016 broad, the third cell slightly swollen. 



Dead stems of herbs, apparently of TlialiGtrum polygmnxim. 

 Mechanicville. May. 



This is closel}^ allied to 0. olivaceus, from which I have sepa- 

 rated it because of its superficial perithecia and constantly 

 five-septate spores.
