condition, usually white or partially white. The specimens should be 

 collected when they are mature, that is, when they are all black 

 They never get too old to collect and furnish all the data, but they 

 are often gathered too young. 



"XYLARIA" FLABELLIFORMIS. In our article on Isaria 

 flabelliformis, Myc. Notes, p. 547, we state that we think no one 

 but Schweinitz ever claimed to have found any but conidial spores 

 We forgot to mention it, but we were aware that Cooke had figured

the fruiting body of "Xylaria flabelliformis" Grevillea, Plate 171, 

 Fig. 153 (reproduced, Fig. 906). Of course, Cooke was a wonderfully 

 talented man. It takes something more than ordinary genius for a 

 man to draw a picture of a fungus that he never saw. We present 

 above a photograph (Fig. 905) from nature 

 of "Isaria" flabelliformis, a frequent plant 

 with us. Schweinitz claims that it had a 

 perithecioid stage, and we reproduce his fig- 

 ure (907), which, while crude, was evidently 

 intended to represent the plant. Fries stated, 

 on the basis of Schweinitz's figure, no doubt, 

 that it was the conidial state of Xylaria corni- 

 formis. I do not believe that there is any 

 ground for that, but it was taken up and ap- 

 pears in Ellis' N. A. Pyrenomycetes. And finally Cooke was able, 

 with his wonderful talent, to construct (in his imagination) a perfect 

 plant (Fig. 896) which no one but Cooke (in his imagination) ever 

 saw. 



XYLARIA SCHWEIXITZII, SENT BY DR. SYLVIO BO- 

 NANSEA, MEXICO. This species was originally collected in Surinam 

 by Dr. Hering, of Philadelphia, and given to Schweinitz. Schweinitz did 

 not publish it, but named it in manuscript Spheria capitata. After 

 Schweinitz's death his herbarium was sent to Berkeley (Note). Ber-
