Tharp: Texas Parasitic Fungi

or subbiseriate, ovate, with both ends subacute, hyaline, unicel- 

 lular, 12-19 X 4-5-5 



On living leaves of Acacia wrightii Benth., Cotulla, Texas, Feb. 

 21, 1916, B. C. Tharp. Differs from P. acaciae P. Henn (Syl- 

 loge 11 : 368) in size of stromata, size and shape of asci, and in 

 size of spores, though the latter point of difference is slight. The 

 description in question, however, seems to me to be wholly too 

 short to be satisfactory.
