170 BOTANICAL GAZETTE. 



The species belongs to the section Bfsiij)iiiafi. The specimens in- 

 dicate that the plant is composed of numerous small unequal and 

 irregular confluent tubercular masses whose porous surface gives them 

 a somewhat spongy appearance. The irregular and uneven surface 

 of the whole mass is probably due mainly to the character of the 

 place of growth. 



BoviSTA SPINULOSA. — Globose, sessile, two to four inches in diame- 

 ter, whitish, becoming tinged above with yellow and brown, the pe- 

 ridium thick, firm, subcorky, the upper part cracking in rather large 

 areas; capillitium and spores dingy-olive inclining to brown ; liocci 

 pale, usually branched, bearing scattered unequal spine-like pro- 

 cesses; spores globose, colored, minutely warted, .0004-0005 of an 

 inch in diameter. 



On or near dung of domestic animals in open places. New Mexi- 

 co. C. W. Irish. 



This is a remarkable species unlike any other American Bovista 

 known to me, both in its thick firm and gourd-like rind or peridium, 

 and in its pale subpellucid filaments which are armed, especially to- 

 ward their extremities, with prominent spinules. Its spores, too, are 

 larger than those of our other species. 



According to the notes kindly furnished me by Mr. Irish, the jjlants 

 grow in groups of from five to fifteen individuals. They were seen 

 here and there along a trail a distance of about forty miles. When 

 fully developed they are easily loosened from their place of growtli 

 and are blown about by the winds. None were found growing in the 

 shade and in some instances small and immature specimens appeared 

 to have been killed by the heat of the sun. 



Septoria podophyllina. — Spots large, indefinite, reddish-brown; pe- 

 rithecia epiphyllous, few, clustered on or near the center of the spot, 

 pallid or blackish, slightly prominent, collapsing when dry; spores 

 filiform, variable in length, straight or slightly curved, ,0008-0015 of 

 an inch long.

 municated by Prof. S. A. Forbes. 



Septoria Lactuc^e. — Spots indefinite, pallid or brownish ; i3erithecia 

 minute, scattered, blackish; spores straight or slightly curved, .0008- 

 .0015 of an inch long. 



Living leaves of lettuce, Lactuca sativa. Illinois. Forbes. 



Septoria Trillii. — Spots suborbicular, wdiitish; perithecia numer- 

 ous, crowded, especially on the center of the spot, black ; spores fili- 

 form, straight or curved, .0008-0016 of an inch long.
