C. laxa Rost.—Not common ; appearing on dead wood 
at many times of the year, perhaps most frequently in winter. 
C. fimbriata G. Lister and Cran.—The first gathering of 
this elegant little species was made in November 1913, by Mr. 
Raymond Finlayson, who found a growth of nearly forty 
sporangia on a decorticated bramble stick in Wanstead Park. 
When first found the spores were not shed, and the sporangia, 
although measuring only a fifth of a millimeter in diameter were 
almost conspicuous compared with the shadowy objects they 
now appear, when the spores have fallen away and only the 
hair-like stalks crowned with a scanty tuft of most slender 
capillitium threads remain. Mr. Cran has since found C. fim¬ 
briata in two places near Aberdeen with the distinguishing 
features well-preserved ; these features are the small size of the 
sporangia and the radiating capillitium threads which are 
little branched and extremely slender, except at the tips where 
they often fork and expand into clavate extremities. 
C. pulchella (Bab.) Rost.—Very abundant from late summer 
to winter on dead leaves, especially those of oak and holly ; 
var. fusca Lister was described from specimens found in Wanstead 
Park in September 1896 ; it was then abundant on dead bramble 
and elm leaves, but we have not met with it in Essex since 
elsewhere it has been obtained from near Bath, Worcestershire, 
N. Wales, Aberdeen, Ireland and Switzerland. 
C. rubens Lister.—Not common ; it has been found on dead 
leaves, chiefly in the winter, both in the Forest and in Wanstead 
Park. 
C. typhoides (Bull.) Rost.—Very frequent on decayed wood 
throughout the summer and autumn ; var. microspora Lister 
was abundant in Wanstead Park on dead bramble leaves in the 
autumn of 1896-7, but has not been found there since ; it has 
been recorded from Surrey and Dorset ; also from Schleswig, 
from near Berlin and from Ohio ; the var. heterospora, frequent 
on dead coniferous wood, has not yet been recorded from Essex. 
Enerthenema papillatum (Pers.) Rost.—Abundant on de¬ 
corticate oak logs ; appearing throughout the year in favourable 
seasons, but especially in winter : sometimes occurring on 
mossy bark of living trees four or five feet from the ground. • 
Lamproderma scintillans (Berk. & Br.) Morgan.—Common 
on dead leaves, especially on those of holly, from autumn to
