JOURNAL OF MYCOLOGY. 



[Vol. 1, 



Darlitca iNTERSEMmATA, Winter.— Perithecia gregaria s. dense 

 sparsa, superficialia, panctiformia, globosa, demum collapse, poro per- 

 tusa, membranacea, fusca, 80—130 ij- diameter. Sporge oblngse s. oblongo- 

 cylindracege, utrinque rotundatse, hyalinse, uni-{rarissime bi-) septatse, 

 ad septum vix vel perparum constrictse, 12—14 long^, 3 IJ- crassse. On 

 leaves of Stellaria with Peronospora Alsinearum, Casp. 



DoAssANSiA DECiPiENS, Winter.— Acervuli epiphylli, greges minu- 

 tos, rotundatos irregularesve, interdum confluentes, pallide fusco-luteos, 

 in macula indeterminata, luteola insidentes, 1—5 mm. diameter, metien- 

 tes, formantes, punctiformes, rotundati sen elliptici, plerumque dense 

 stipati, non raro confluentes, fusci, immersi, 100 — 200 m lati, e sporis 

 numerosissimis, densissime conglobatis, a tegumento tenuissimo, pseudo- 

 parenchymatico, e cellulis minutissimis, fusciscontexto, dense applicato, 

 undique circumdati. Sporse rotundato-polygonise, isodiametricse (sit 

 venia verbo !) vel subellipticse, ssepe irregulares, pallide fuscidulse, Iseves, 

 10—16 fJ' diam. in planta adhuc viventi germinantes. Sporidia filiformia, 

 tenuissima, ssepe flexuosa, usque 70 p- longse, vix 1 p crassse. On leaves 

 of Limnantfiemum lacmiosum. Leg. E. A. Rau., Green Pond, Morri Co., 



J., Aug. 1883. This is a very interesting but doubtful species. 



SUPPLEMENTARY NOTES ON RAMULARIA. 



Whether the mycelium in all the species spreads through the inter- 

 cellular spaces of the leaf, cannot perhaps be positively stated, but this 

 is very plainly the case with some. In R. Tidasnei, 8acc., the creeping 

 threads of mycelium among the inner cells of the leaf are very noticea- 

 ble. The fertile hyphse also often buist out from little pustules, like the 

 young pustules of some uredo, and sometimes apparently they are quite 

 superficial. 



Ramularia macrospoka. Pres. var. Senecionis, Sacc— On leaves of 

 Aster Novce Anglice, Wis. (Trelease.) To the naked eye resembling the 

 conidiaof Entyloma Compositarum, Fsivl. Conidia colorless, 1— 4-celled, 

 usually 2-celled, oblong ovoid, slightly truncate at the pointed extreme, 

 ties, sometimes narrowed gradually to the septum, 20—40 x 5—6 !■>■. This 

 species w^hich should have been included with the others in the June l^o. 

 of the Journal was overlooked. The description is copied from the 

 Prelim. List of the Parasitic Fungi, Wis., p. 13. 



Ramularia crypta, Ck. Grev. XII, p. 27.— The description of this 

 species which was overlooked (see p. 82 of this Journ.) is given below: 



"Hypophylious, covered by the tomentum of the leaf. Hyphse thick 

 (crassse), simple, short. Conidia cylindrical, obtuse at each end, straight 

 or slightly curved, hyaline, 25—30 x 6 A'-."
