tria as E. gossijpii, quoting with a slight rearrangement of words the 

 description of Fries.

 cardo's name, gives an incomplete translation of the Latin description, 

 and adds: 



We have seen no specimens of this species, hut have received from Prof. F. L. 

 Scribner a Fiisarium on capsules of cotton from South Carolina, which may he the 

 conidial stage.

Sphseria Gossypii, Schw. Syn. Car. 207. 



This is an obscure thing. The inner membrane of the cotton boll is wrinkled or 

 roughened in drying so as to give the appearance of minute perithecia, but there is 

 no fruit nor even any real perithecia. 



(7) Curtis. In Dr. Farlow's herbarium, at Cambridge, Mass., is a 

 fragment of cotton capsule labeled "Sphoeria gossypii Schw." This 

 came from the herbarium of M. A. Curtis, who received it from de 

 Schweinitz. On the pocket in the handwriting of Mr. Curtis is a pen- 

 ciled memorandum to the eft'ect that this is not a fungus. Neither the 

 writer nor Dr. Farlow, who examined the specimen with him, could 

 find any Sphiieriaceous or Nectriaceous fungus or any Fusarium spores 

 on this specimen. 



(8) Dr. Karl Starback, who kindly examined for me the Schwei- 

 nitzian material of this species sent to Dr. Fries, and now preserved in 

 the Fries collection at Upsala, writes that no fungus whatever is pres- 

 ent and adds: " Species Schweinitzii Sph. gossypii est typicus observa- 

 tionis et auctoris et Friesii." 



(9) My own examination in July, 1899, of material preserved in the 

 de Schweinitz herbarium in Academy of Natural Sciences of Phila- 

 delphia, led to no different result. The specimens were examined both 

 by reflected and transmitted light, with a hand lens and with the com- 

 pound microscope. 



The specimen in the collection proper (books of Sphterias) is labeled 

 "Sphferia gossypii L. v. S. and Fr. Salem." This pocket contained 

 nothing but some dust particles, insect detritus, and fragments, the 

 largest of which was less than 1 mm. in area. These dust partitles and 

 fragments showed no perithecia or Fusarium spores. No fungus with 

 necks either long or short was to be seen. Traces of an unknown, col- 

 orless, very delicate mycelium were observed, and one Macrosporium 

 spore. This pocket also contained the skin of a museum pest. 



In a separate package labeled "Fungi | Cryptograms | fr. Dr. Schwei- 

 nitz I to Collins," I found, however, an uninjured, well-preserved speci- 

 men labeled in the handwriting of de Schweinitz " Sphwria Gossypii L. 

 V. S. and Fr. Salem." This pocket contains two fragments of cotton
