only a Diplodia." Careful examination of the type material finally 

 yielded mature asci. The perithecia are not typical of the genus. 

 They are nearly twice as long as wide at the base and although 

 pertusate, are not circularly so. The asci are eight-spored, various 

 in shape, the longest reaching 135 /x densely paraphysate; sporidia 

 brown, one-septate, subbiseriate to congloliate, 27-44x9-15 /;,. On 

 decorticated and decayed wood of Thuja occidentalis L.

 same host in Vermont.

 L. H. D. House, June 8, 1922. 



This must be regarded as a tentative determination since the 

 material is not abundant, nor is there an authentic specimen avail- 

 able for comparison. The measurements are approximately those 

 of the species named. The noncollapsing perithecia contain asci 

 weak and variable in shape, average about 120 /x in length, eight- 

 spored. densely paraphysate ; sporidia variable, about 17-21 x 9-10 //. 

 three-septate, constricted at the septa, becoming so opaque as to 

 obscure the septation.

Guignardia Pleurothallis Dearness & House, sp. nov. 



Perithecia epiphyllous, gregarious on areas of .5-1 cm which are 

 greener than the surrounding portions of the leaf, finally thickly 

 scattered over the v^^hole leaf, dark brown, .1-.2 mm, waxy mem- 

 branous. Asci fusoid or clavate, mostly about 45 x 10 fx, surrounded 

 by a few indistinct paraphyses. Sporidia subbiseriate, grumous- 

 h'yaline, some of them curved, depending upon their position in the 

 ascus, variable in size as well as shape, mostly 12 x 2-3 /x.
