Aleuria olivacea, Boud. Sessile, 3-5 cm. broad, entirely olive- 
fuscous, outside furfuraceo-granulose, spores elliptic-fusoid, 
verruculose, 22-23 X 10-IIu. Somewhat resembles Peziza 
badia, but distinguished by the spores. 
Ascophanus (Cubonia) dentatus, Boud. Pale brown, the mem- 
branaceous margin broken up into triangular teeth; spores 
globose hyaline, 9-10m. 
Flelotium fuluum, Boud. Stipitate, up to 0.5 mm. broad and 
high, tawny-brown, hymenium and base of pedicel darker ; 
spores elliptic-oblong, hyaline. 16-21 x 7-Iou. Growing on 
mosses in the axils of the leaves. 
Helotium cuniculi, Boud. Stipitate, 2-3 mm. broad and high, 
ochraceous-yellow, hymenium darker, and with a tawny margin; 
spores oblong-fusiform, becoming I-septate, hyaline 16-20 x 6-7.

PH ZOMARASMIUS. 
Under this name Von, A. Scherffel (Hedwigia, 1897, p. 288, 
figs. 1-3) has founded a new genus for the reception of species 
previously included in the genus Muarasmius, Fries, characterised 
by having coloured spores, the colour ranging from yellow to fer- 
ruginous, whereas the species left in A/arasmius must have hyaline 
spores. A new species, P. excentricus, having a sulcate, ferruginous, 
tomentose pileus 3-5 mm. across, and a short, excentric, curved 
stem is described. It occurred on living bark of Pyrus communis, in 
Hungary. Some of our British species will go into this genus. The 
above idea is in accordance with the arrangement adopted by Saccardo 
in the “Sylloge Fungorum,” and has its advantages. The dis- 
advantage is as follows:—A@arasmius is a very natural genus, as 
defined by Fries, but split up as above, the white-spored section will 
be placed in the Leucosporz, and next to Collybia, its nearest ally, 
whereas the coloured-spored section (Pheomarasmius) must be placed 
in the Ochrospore, miles away from the white-spored section, and 
near to Galera, with which it has not the slightest affinity. Ina similar 
manner the genus Russula might be broken up into an emended 
Russula with white spores,and a new genus Pheorussula, characterised 
by having yellow or ochraceous spores, as follows—Characteres generis 
Russule, sed sporis favidis, ochraceis. This genus would have to be 
located in the Ochrospora, where it has no affinities. The founding 
of genera on any one character is always objectionable, but the above
