I en föregående uppsats (Sv. Bot. Tidskr. p. (7). Bd 4, 1910) har
jag påpekat denna arts tydligt arktisk-alpin-maritima utbredning inom
Skandinavien. Detta nya fynd ger ytterligare stöd åt mitt antagande,
då fyndorten är belägen ett godt stycke ut i Stockholms skärgård.

RESUME.
New for Sweden is Taphridium Cicutae Liro on Cicuta virosa. Seldom
found are: Urophlyctis Lathyri Palm on Lathyrus montanus, Peronospoı a
lapponica Lagerh. on Euphrasia officinalis, Entyloma Sparganii Lagerh. on
Sparganium ramosum, Urocystis Luzulae (Schröt.) Wint. on Luzula pilosa,
Urocystis Kmetiana Magn. on Viola tricolor, Phragmidium obtusum (Strauss)
Wint. on Potentilla Tormentilla, Pucciniastrum sparsum (Wint.) Ed. Fisch.
on Arctostaphylos uva ursi.
On new or interesting hostplants the following fungi have been found:
Bremia Lactucae Regel on Senecio elegans, Phytophtora infestans (Mont.)
De By on fruits of Solanum melongena, Taphridium Umbelliferarum on
Laser pitium latifolium, Coleosporium Senecionis (Pers.) Lév. on Senecio Led: -
bouri. Special mention deserve Cronartium asclepiadeum (Willd.) Fr. on
Tropaeolum minus and a Coleosporium, that temporarily was named C.
Tropaeoli (Desm.?) Palm. It was suspected to be one of the commoniest
Coleosporium-species having occasionally settled over on Tropaeolum; the
question could, however, not be decided. Later KLEBAHN (Zeitschr. f.
Pflanzenkrankh. 1914, p. 14—18) by means of cultural studies found
Tropaeolum liable to attacks from the following specis of Coleosporium :
C. Campanulae (Pers.) Lev., C. Tussilaginis (Pers.) Kleb. and C. Senecionis —
(Pers. Fr. All these were found, too, growing on a variety of hostplants -
