NOTES ON SOME PUBLISHED SPECIES OF 
FUNGI. 
BY J. B. ELBIS. 
Ch.etomella (v) perfokata, E. & p]. Jonrn. MycoL, I, p. 158. 
Since the publication of the above. Prof. T. J. Burrill, of the Uni¬ 
versity of Illinois, has sent ns mature specimens (on Cirsium discolor), 
showing that the supposed Choatoynella is really an ascigerous fungus, 
which we refer to Ventmia, since, although it has 8-septate sporidia, all 
the other characters place it in that genus. 
It may be characterized as follows : 
Yenturia occidentalis, E. & E -- Perithecia as previously de¬ 
scribed, membranaceous and of coarse cellular structure, subhemispherical 
rather than globose; asci subcylindrical, about 75—100 x 7—10 (with im¬ 
perfect paraphyses V); sporidia oblong-fusiform, 8-septate when mature, 
and constricted at the middle septum, or often at all the septa, nearly 
hyaline, 20—25 x 4—5/'. Most of the perithecia contain only stylospores. 
Var. MINOR on Artemisia ludoviciana has asci smaller (50—60 x 6—8 r -) 
and paraphyses more robust; sporidia about 15x8 oval, and the middle 
slightly colored. 
Uncinula polych^ta, 13. & C.—In the description of this species, 
published in Grevillea, Vol. IV, p. 159, and in Saccardo's S 3 dloge, Vol. 1, 
the number of appendages is said to be “•about 28,” and the number of 
asci is not stated. In a recent examination of some South American 
specimens from Prof. Spegazzini, I found a perithecium (the ordy 
mature one examined) containing fiftv 2-spored asci, and surrounded 
by over 200 appendages, 114—120 x 6—7 hyaline, continuous, with 
attenuated, involute tips. Perithecia 225—280 in diameter. 
The foregoing notes are also applicable to the specimens of Uncinula 
polychoeM^ 13. & C., in Haveners Fungi Garoliniani. The species is re¬ 
markable for its numerous asci and appendages, but it seems unneces¬ 
sary, on this account, to make it the type of a new genus. Possibly the 
statement that the number of appendages is “ about 28” is a typograph¬ 
ical error for about which would be nearer the actual number. 
CiiRo^rosRORiUM VIRIDE, Coi’da.—What appears to be this species 
was found by Dr. Geo. A. Rex, in the Adirondack mountains, August, 
1885, forming a thin, dirtj'^-green continuous layer on the surface of rot- 
ton wood, extending for several inches, and consisting, almost entirely, 
of transparent, greenish, granular, subglobose conidia, 12—16 !j- in diam¬ 
eter. The layer of conidia was traversed by a few obscure hyaline, 
mucedinous threads, but as the specimens were already past their prime, 
no very accurate adea of the origin of the conidia and their mode of 
attachment could be formed. 
The specimen in Saccardo's Mycotheca Veneta, 1566, has the conidia 
smaller (8—12 !>■) and the color of the layer is darker, but this may be due 
to the application of poison. In Saccardo's specimen, the conidia are 
evidently borne at the tips of short, sparingly branched upright threads.
