Newfield, N, J., May 1885. Acervuli hysteriform, covered 

 at first, then partially erunipeiit. Spores oblong- elliptical 

 or oLovate, 4-septate with a short, narrower, subconical, 

 hyaline cell at each end, intermediate cells brown. Crest 

 ot 3 hyaline, spreading bristles about 7 — 10 /* long. Basidia 

 about as long as the spore, slender. Colored part of the 

 spore 12—16 x 6—7 ^i. Differs from P. funera, Desm., in 

 its constantly smaller spores. 



Asterina discoid ea, E. & M., in Am. Nat. This occurs 

 also on leaves of Olea Americana, not differing specially 

 from the form described on leaves of Quercus laurifolia. 

 It may be that this is the A. oleina, Cke., Grev. XI, p. 38. 

 The description there given is not inconsistent with this 

 supposition. In that case, A. discoidea, E. & M., is a syno- 

 nym of A oleina, Cke. Unfortunately, the specimen of this 

 latter species in Rav. F. Am., no. 757, in our copy, does 

 not show even a perifheclum. 



Microsphaera dcnsissima, Schw. ~ What appears 

 to be this species was found on leaves of Quercus laurifolia, at 

 Green Cove Springs, in January and February, 1885. Myce- 

 lium thick, gray, persistent, confined to definite spots on 

 the lower surface of the leaf", 8— 10 mm in diameter. Peri- 

 thecia black, globose, (hen depressed, 120 f-i. Appendages 

 stout, continuous and suljhyaline, twice dichotomous, ultimate 

 divisions curved, 96—120 x 7 |U. Asci 6. Sporidia 6—8, 

 oval, granular and nucleate, 21—25 x 12 /w. The branched 

 tips of the appendages are often of a pyramidal shape, the 

 main axis running through and bearing a second set of 

 branches shorter than the first.

Wir haben schon mehrfach die Aufmerksamkeit unserer 

 Leser auf diese werthvolle Sammlung hingclenkt und woUen 

 nicht verfehlen, auch dieser beidcn neuen Centurien ruhmend 

 zu gedenken. Ellis hat es verstanden, sicb fast in alien 

 Thcilen des riesigen Unions -Gebietes Mitarbeiter fiir seine 

 Exsiccaten zu verschaffen, so dass die siidlichen wie die 

 westlichen Staaten stets durch einige Formen vertreten sind, 

 die uns deren interessante Flora vorfiihrcn. Wiihrend die 

 14. Centurie Pilze aus alien Abtheilungen mit Ausnahme 

 der Uredinei, Ustilaginei und Peronosporei enthiilt, bringt 

 die 15. Centurie nur Formen aus diesen drei Familien. Be- 

 sonders reich sind die Uredineen vertreten, unter denen sich
