and spores, 8 » diam., are similar to those in former gatherings. 
Ertonema avreum Penzig, Pl. 458, 1. ¢., leg. S. Kusano, Sept. 1902. 
This gathering represents the second recorded occurrence of the 
the Buitenzorg Gardens.* The minute round granules of lime 
Prof. Penzig may warrant its being placed in a separate genus. 
The specimen from Japan presents precisely the same characters 
as that from Java, and, as no figure has hitherto been published, 
we give a plate to illustrate its exceptional habit. The prominent 
e 6-7 pdiam. § 
septica show a near relationship to Hrionema.

Dipymium pirFrorme Duby, var, comatum, l.c., leg. S. Kusano, 
Aug. 1898. This specimen is the variety described in a previous 
article in this Journal.} The sporangia are of the usual form met 
with in this country; the capillitium consists of crowded, straight, 
colourless, anastomosing threads; they are of equal thickness 
throughout their length, and do not taper upwards from a thickened 
base, as in the typical form. In January, 1903, we met with this 
variety in abundance on dead fern and nettle leaves on the Under- 
cliff, Lyme Regis; the normal form was also present, but sparingly: 
several sporangia had capillitium of intermediate character showing 
various stages connecting the profuse slender threads of the var: 
comatum with those of the normal type; this confirms the view that 
€ var. comatum is not a distinct species.
