SOME EXOTIC FUNGI. 
Pileus 3^in. broad, scarce ^in. thick. Stem about an inch long, 
and over one-third of an inch thick. Allied to P. flabelliformis, but 
differs in the "whiter hymenium, much larger and toothed pores, 
and the snowy whiteness of the flesh, which is soon destroyed by 
insects.

OYULARIA BULBIGERA, Sacc. 
A short visit this summer to the classic ground of the keen- 
sighted mycologist of the Rhine produced, among other things, a 
minute fungus on the leaflets of Poterium Sanguisorba, which 
appears to be identical with his rare Scolicotrichum bulbigerum 
(Symb. Myc., p. 106; Ovularia bulbigera, Sacc. Syll. iv., 140), 
but differs somewhat from his description. It causes small, 
roundish, pale-ochreous spots (2-4 mm. diam.) on the leaves. 
These spots are visible on both surfaces, but on the upper surface 
they are surrounded by a purplish-brown border (^-1 mm. broad), 
which does not show beneath. The spots, in fact, closely resemble 
those of Septoria Pubi, but are "without the greyish tinge of the 
latter. The fungus is produced only on the lower surface, and pre- 
sents the usual appearance of an Ovularia ; the hyphse are in 
dense, pure white tufts, about ^ mm. high, the tufts being 
thickly scattered over the whole lower surface of the spot, and 
forming, when full grown, a thin crust, like, but less dense than, 
that of 0. sphceroidea, Sacc., to which in other respects this fungus 
bears a slight resemblance. The hyphee are from 70 to 130 mk. 
long, 4 mk. thick, simple or occasionally branched, hyaline, con- 
tinuous or rarely 1-septate, flexuous, here and there denticulate, 
and so closely attached to one another longitudinally that it is 
difficult to separate one from the mass. At the tapering apex and 
on the denticules are borne sub-globose or slightly ovoid conidia, 
9-11 mk. in transv. diam., and reaching a length of 15 mk. 
So far the fungus agrees with Fuckel’s diagnosis (except that he
