sometimes horseshoe shaped, usually umbilicate in the centrej 

 waxy-looking, minutely pruinose, pale yellow-brown or dark 

 amber, surrounded by a paler fibrillose hypothallus, 0'l-0'2 

 mm. wide ; ostiola inconspicuous, circularly arranged, 

 radially elongated, irregularly oval, upto 0"15 x O'l mm., or 

 sometimes labyrinthiform, pale yellow with a darker edge ; 

 pycnidia radially elongated, in transverse section oval at first, 

 then opening widely, slightly convoluted at the base, up to 

 160 \L deep ; pycnospores broadly fusoid and sometimes 

 inequilateral, or subcylindric, 5-7 X 1'5 (j, ; paraphyses 

 linear, 60-160 [l long.

At first sight this appears to belong to the discoid 

 group, resembling in shape A. viridans or A. samoensis. Its 

 pycnidia, however, are not regularly globose as in those 

 species, but approach the widely-open convoluted pycnidia 

 of A. Aleyrodis, A. placenta, &c. It falls into the same 

 group as A. Tamurai and A. taitensis. 



Specimens of Aschersonia brunnea, collected by Mr. A. T. 

 Speare on Ilex Cassine, Winter Park, Florida, July, 1920, 

 extend the known range of that species, and furnish additional 

 information concerning its colour. It was described and 

 figured as dark purple-brown from the only specimens known, 

 viz., those in Herb. Kew collected in Brazil by Spruce. These 

 recent specimens are yellow-brown, sometimes with a green 

 tinge, more nearly resembling Aschersonia hadia. It is 

 possible that the darker colour of the old herbarium speci- 

 mens may be due to the action of some preservative. The 

 paraphyses of these Florida specimens are up to 200 \x 

 long. 



From the same locality and on the same host plant, Mr. 

 Speare has forwarded specimens of Aschersonia basicystis, the 

 flattened-pulvinate, white form with scattered pycnidia. The 

 extruded spores on these examples form isolated heaps, often 

 cylindrical, up to 0"25 mm. high. The spores measure 14-17 

 X 2-2 "5 jx, and are oval with tapering ends.
