LIST OF SPECIES RECORDED FROM ESSEX. 41 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, chief!}' 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
