neue Uredinoen-Gattungen mit tremelloider Entwickelung. (Vorl'aufige Mittheilung). 
<Ber. d. deutsch. bot. Gesell., 9. Jahrg., lieft 10, Berlin, Jan. 24, 1892, pp. 
344-348. 
Gives a preliminary notice of four interesting new genera of tremelloid Uredinece. Puc¬ 
ciniosira resembles Endophyllum , but has two-celled smooth spores. Two species are 
described. P. triumfettce on leaves of T. sp. in Equador aud on T. abutiloides in Brazil has 
colorless spores, which have attached to them the empty intermediate cell and do not fall 
apart into two cells in germinating. Only teleutospores are described. The second species, 
P. solani on leaves of Solarium sp. in Equador, differs much from the first; the spores are 
produced in chains which adhere to each other laterally. The spores are orange yellow and 
in germinating fall apart into two cells. The intermediate cells disappear early in the de¬ 
velopment of the fungus and nothing can be seen of them when the spores are mature. 
Spermogonia and teleutospores occur. In a footnote -it is mentioned that a Leptopuccinia 
occurs on Oestrum , and another on Solanum in Equador, making with Pucciniosira three 
tremelloid TJredinece known on the family Solanacese, though none were previously known. 
Chrysospora has brigl# red sori containing teleutospores like Puccinia in structure. In 
germinating each cell divides into four segments, each of which produces a large sporidium 
on the end of a unicellular promycelium. The genus resembles, therefore, a Coleosporium in 
which the teleutospores become segmented just before germination. Spermogonia and 
teleutospores occur. A single species, O. gynoxidis , is described which occurs on leaves or 
occasionally on young shoots of Gynoxis pulchella EC. and G. buxifelia DC. in Equador. 
A Iveolaria produces cylindric ringed columns consisting of a series of disk-like teleutospores 
which are composed of manv prismatic cells. The cells have a smooth membrane. The 
spore disks ripen in basipetal order and are loosened in germination, which proceeds as in 
Puccinia. Only teleutospores are produced. Two species are described. The first, A. 
cordice, occurs on leaves of Gordia sp. in Equador and has spore-disks 120-150 u wide and 
40-50 n high, consisting of 30 to 00 cells which have yellowish walls and colorless cell 
contents. The second, A. andina , occurs on a very different Gordia in Equador and has 
spore-disks 180-210 n wide and about 70 y high, composed of very numerous cells, which 
have bright orange-colored contents. Trichospora has filiform orange-yellow sori similar in 
structure to those of Gronartium and composed of more or less spool-shaped teleutospores 
and sterile cells. The membrane of the teleutospores is colorless and thickened at the ends; 
the contents are orange red. The sterile cells, which occur among the teleutospores, are 
very narrow and long and contain a reddish cell content. The germination of the teleu¬ 
tospores is very different from that of Gronartium. The young spores are unicellular, but 
when ripe are divided by three delicate septic into four colls, each of which produced in ger¬ 
minating a unicellular promycelium with a single sporidium. One species, T. tournefortioe , is 
described. It is very common in Equador on all parts of two species of Tournefortia. Both 
spermogonia and teleutospores are produced. The spermogonia are unusually large and 
have spermatia with red cell contents. (AV. T. S.)

States that the name of the fungus should be Uromyces exeavatus (DC.) Magn., not U. exca- 
vatus (DC.) Berk. It is different from U. excaoata (DC.) of Berkley and of Cooke, which is 
really U. tuberculatus Eckl. (W. T. S.)

Sulla Puccinia gladioli Cast, e sulle Puccinie con paradsi. <(Nuovo 
Ital. (Bull. d. Soc.), vol. xxm, Firenze, 5 Ottobre, 1891, pp. 
Records Puccinia gladioli Cast, on Pomulca ramiflora Ten., a new host, as possessing 
parapliyses. Refers to omission of the species from Soliroeter and Winter, and imperfect 
description of geographical distribution by Saccardo & Celotti, giving corrections and full 
synonomy. Discusses presence of parapliyses in Puccineae, preferring to consider them as 
constituting secondary characters only. Adds list of species with parapliyses as follows: 
P. anemones-virginiance Scliw., P. gladioli Cast., P. virgaurece , P. allii, P.polygoni-amphibii 
Pers., P. sonclii Rab., P. pruni-spinosce I’ers., P. rubigo-vera, P. cordce Bagn., P. gibberosa
