NOTES ON THE DISCO MYCETES.

Cooke (“ Rehm. Ascom.,” 54) has altogether a different sporidium 
than Cooke shows, presuming that I have before me the right 
species in my description (in the u Flora,” 1872). My description 
states there “ sporidiis subdistichis, oblong o-lanceolatis, continuis, 4 
guttulis oleosis, hyalinis, 24-36 mik. lang, 7-9 mik. crass.” Cooke 
represents the sporidia as elliptical, uniseriate, and gives their size 
as 20 mm. long, 9 mm. broad. Perhaps two distinct species were 
growing intermixed. 
With regard to Peziza mirabilis , Borsze, the great similarity of 
this fungus to the figure of Pezizi protracta in “ Gon. and Rabh. 
Myco. Europ.,” Tab. i., Fig. 2, strikes every one. After all the 
information communicated by Borszcow respecting his fungus, there 
is no essential difference shown between it and Peziza protracta. 
Sclerotinia baccata, Fuckel (“ Symb.,” p. 331), and Microstoma 
hiemale, Bernst., are also indentical with these (“ Acta. Acad. 
Leopold. Carol.,” 1852), so that this fungus has been described 
four times as new ! The figure of Peziza leucomelas , Pers., by 
Cooke, is not particularly successful ; that in Sturm’s “ Deutschl. 
Flora,” is far more correet and beautiful ; there may be found, also, 
a figure of this species in Persoon’s “ Mycologia Europaea,” iii., 
Tab. 30, Fig. 1, a, b, c, without, it is true, a corresponding, 
account in the text. 
A great confusion still prevails, especially in reference to Peziza 
reticulata , venosa and aucilis. In April of this year I found Peziza 
reticulata in different places about Zurich, and have also received it 
from other places in Switzerland, so that about 30 living specimens 
lie before me. The species is, in reference to size, form, and folds, 
extraordinarily variable. I found five specimens growing near each 
other measuring from 89 to 158 mill, across, strikingly differing 
one from the other in form. While the largest specimen nearly 
answered to the upper figure of “ Greville. Scott. Crypt.” Flora, 
iii., Tab. 156. Another was about the shape of an umbrella, 
that is, the cupula was strongly convex, its margin inclined down- 
wards, the stem very long and thin, the disc furnished with delicate, 
scarcely noticable, wrinkles. One specimen from Stein, on the 
Rhine, had very much the form of Greville’s lower figure, being 
about 150 mill, long, and nearly the same breadth, with extra- 
ordinarily prominent narrow ribs. I found one near Zurich 
altogether similar, only smaller, with stout projecting ribs, in the 
midst of others which were quite smooth. Also the odour, which 
Cooke makes particularly prominent, is throughout absent ; it is 
found present in mature specimens only ; I could observe no trace 
of it in about ten specimens gathered when young. The species is, 
under all circumstances, notwithstanding their variable forms and 
sizes, easily known by the following : — The exterior of the cupula, 
particularly near the margin, is clothed in a more or less distinct 
manner with numerous triangular-form pale brown scales, which, 
though often washed off, were always recognisable on mature un- 
injured specimens. Moreover, the sporidia (which in the specimens
