190 ARTHUR-BISBY— TRANSLATION OF SCHWEINITZ'S 



and by the original packet, empty, labelled on the front " Sphseria 

 epiphylla LvS . . . Salem . . .," a portion not being legible, and 

 on the folded end " Sphseria epiphylla Salem." 



While Dietel was making a study of the genus Ravenelia, he 

 received a fragment of the original Schweinitz collection, sent by 

 Lagerheim from the Herb. Fries, from which he was enabled to 

 transfer the species to that genus {Hedwigia, 33:27. 1894), 

 although he points out that the true nature of the fungus had 

 already been detected (Farlow & Seymour, "Host Index," page 

 30. 1888). The name is now generally written Ravenelia epi- 

 phylla (Schw.) Diet. 



*I487. 342. S[phaeria] canaliculata, L.v.S., of the same group [as the pre- 

 ceding species, i486], but abundantly distinct, Bethlehem, on 

 leaves of the involucres of Cyperus, found on the dorsal surface. 

 S. covered, dark, composed of series of perithecia situated between 

 the striae of the leaves, parallelly confluent on a pitch black spot, 

 so that the spot appears beautifully canaliculate ; rather large. 

 Ostioles thick, punctiform. On the margin occur subsolitary, 

 subrotund, applanate perithecia. In the middle, moreover, the 

 pitch black spots are sometimes sterile — and, it may be noted, the 

 spot is frequently interrupted at intervals of a quarter of an inch, 

 so that the unaltered substance of the leaf comes into view. 



Represented by a mounted specimen, consisting of a portion of 

 five leaves, originally six, one having become detached and lost, 

 each portion about 5 cm. long and 6 or 8 mm. broad, well supplied 

 with uncovered uredinia and covered telia. The original packet 

 contains two small pieces of leaf, and is labelled " Sph. canaliculata 

 LvS in Scirpi involucr." It was evidently first labelled " Sph 

 graminis," as the word " graminis " has been crossed out. 



The true character of this fungus was first pointed out by Lager- 

 heim {Tromso Mtis. Aarsh., 17:51. 1895), from the study of an 

 original autographic specimen in the Fries Herbarium. It is now 

 called Puccinia canaliculata (Schw.) Lagerh., and is a widespread 

 American species.
