turity to a pinkish red. Spots depressed^ irregular, broad, of- 
ten very confluent, and less dense at their edges. Tubes re- 
markably turbinate and mushroom-shaped, varying sometimes 
to cuneiform. This plant differs entirely from Ei cicerinim^ 
with which De CaUdolle, in the FI. Franc.<i has confounded it. 
At present it is not known in Great Britain eVen as a varietyi 
it is found on the under surface of the leaf^ and remains as long 
probably in perfection as the preceding^

Of a splendid gold colour, becoming dingy in old age. Wheit 
in distinct spots, immersed ; when widely effused, so as to cover® 
nearly the whole inferior surface, which is soUietimes the case^ 
the leaf is collapsed more or lessj and has, at first sight, the ap- 
pearance of having been the residence of an aphis. It rare- 
ly appears on the upper surface^ aiid then only in small 
spots. The tubes are so minute, that they require a power- 
ful miscroscope, but are then very distinctly seen, from their 
fine yellow colhur; the yellow portion seems to be enclosed 
within a pellucid covering, and probably consists of a mass of 
sporules, which are evidently very numerous, and appear to 
escape by an aperture at the apex. 
I gathered this plant during tha last summer very abundantly 
at Carlowrie near Edinburgh, and in the neighbourhood of 
Glasgow.
