JOUENAL OF MYCOLOGY. 



[Vol. 1, 



finally more or less confluent, hyaline, mostly simple, continuous or 

 faintly 1—2 septate, subundulate and geniculate, 50—80 x 3—4 tips 

 mostly obtuse and showing the marks of attachment of 2—3 conidia one 

 of which is also borne at each lateral projection or knee as indicated by 

 the scars. Conidia oblong, fusiform-oblong or clavate-oblong, mostly a 

 little curved, 1-septate, rarely 2— 3-septate, hyaline, 12—24 x 3i— 4 



On leaves of various species of Desmodium from Carolina (Ravenel) 

 to Iowa (Holway), Kansas (Kellerman) and Wisconsin (Trelease); var. 

 epiphylla, on leaves of Astragalus, Wisconsin (Trelease), differs in its 

 epiphyllous growth and the entire absence of any spots. It forms minute 

 white, punctiform specks scattered rather sparingly over the leaf, and 

 the conidia are perhaps a little larger and with a yellowish tint. 



32. Ramularia filaris, Pres., Beitrag., p. 90. 



Ilypophyllous, whitish at first then yellowish, short (15— 25/^-), fascic- 

 ulate, continuous, subgeniculate. Conidia oblong to cylindrical, concat- 

 enate, 1-septate, 12—30 x oi — 4 The upper suriace of the leaf opposite 

 the patches of hyphse is pale yellowish at first, finally brown. There are 

 no definite spots, the patches of hyphse being at first limited by the areas 

 formed by the veinlets of the leaf, but at length more or less confluent. 



On living leaves of Aster puniceus, Xew Hampshire (Farlow). On 

 leaves of Aster, Iowa (Holway). This appears to be the same as speci- 

 mens in Kunze's Fungi Selecti, 498, but specimens in Eab. Winter, 

 Fungi Eur. 3185, are amphigenous on quite pronounced dull greenish- 

 brown spots, V\ith shorter continuous conidia. Fresenius describes and 

 figures the hyphse (at least some of them) with a bristle-like prolonga- 

 tion above which we have not been able satisfactorily to make out, nor 

 is this appendage figured by Saccardo in his Fungi Italici, 1004.

 Cylindrosporimn Heradei, Oud. Mat. Fl. Mj-col. Fland, II, p. 301. 



Epiphyllous, on browTi, subangular, indefinitely limited spots (2 — 4 

 mm.) Hyphse very short, hyaline. Conidia oblong-cylindrical, 18— 30 x 

 4 — 5 /-'-, the shorter ones 1-septate, the longer ones 3 — septate and subat- 

 tenuated above. 



On leaves of Heradeum lanatum, Massachusetts (Farlow). 



34. Ramularia Yirgaure^e, Theum. Fungi Austriaci, 1072. 

 Tufts effused, mostly hjTpophyllous, on pale, irregularly shaped, sub- 

 angular areas of the leaf which shows yellow patches above (becoming 

 brown). Hyphse in small, compact tufts, hyaline, mostly short and 

 entire but sometimes 60—75 and denticulate above. Conidia cylin- 

 drical, 1-septate, 15—55 x 4 or elongated to 60—75 and 3-septate, hya- 

 line. 



On living leaves of Solidago, from New Jersey to Kansas (Kellerman). 

 This is certainly the same as the specimens in de Theumen's Fung. Aust. 

 and in Kunze's Fungi Selecti. 398, though the specimens in both these 

 collections show some conidia even longer than the N. J. or Kansas spec- 

 imens.
