spore measurements, but from the description apparently differs 

 in possessing perithecia which are clothed with hairs; the type 

 here again is too meager to permit of a fair examination. This 

 latter character is one which is very uncertain in the present 

 genus, the perithecia of many of the species which are usually 

 considered smooth being clothed when young with mycelial 

 threads which often fall off later. This character seems to be 

 very variable depending upon age and other conditions. In only 

 a few cases in the present genus are the perithecia found to be 

 clothed with well-developed hairs.

Perithecia scattered, superficial, nearly globose, with a papilli- 

 form ostiolum, smooth, pale red to yellowish, entire or often col- 

 lapsing, 200-250 mic. in diameter ; asci clavate, 8-spored, 50- 

 55 X 7-8 nlic. ; spores crowded, 18-22 X 4~5 rmc, i-septate, 2- 

 seriate (pi. 5. /. 10, 11). 



On Eucalyptus and stems of Lupinus. 



Type locality: California. 



Distribution : Known only from type locality. 



Specimens examined: California, Harkness (probably co- 

 type). 



Distinguished by the pale perithecia and large fusoid spores. 



Dr. Cooke in Grevillea (1. c.) distinguishes Nectria depailens 

 (Cooke & Hark.) Sacc. from the above by a difference in the 

 color of the perithecia the one being ochraceous and the other 

 testaceous-red and by the larger size of the spores, those of 

 Nectria Eucalypti being 16-18 X 4 mic. and Nectria depailens 

 (Cooke & Hark.) Sacc. 22-24 X 4~4-5 mic - I n tne specimen ex- 

 amined by the writer of each of these species, both of which were 

 collected in California by Harkness and are evidently cotype al- 

 though not marked, the difference in the color of the perithecia is 

 too slight and the character too variable to be considered. While
