Subiculum annual, arachnoid, white, effused forming areas to 10 cm across. Pilei densely aggregated, sometimes confluent, seldom scattered, cylindrical or subclavate, 0.5-3 mm tall, 0.1 -0.4 mm diameter, attached by narrow bases, ceraceous, brittle, white drying honey yellow; pileus surface covered with tortuous encrusted (in part) abhymenial hairs; margin even, inrolled and slightly thickened. Context white, to 35 µm thick, of densely compacted parallel hyphae; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, hyaline. Hymenial layer to 30 µm deep, a close palisade of basidia and paraphyses. Basidia clavate, 12-16 x 5-6 µm, bearing 4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses subclavate, 10-14 x 4-5 µm. Spores subglobose, a few globose or oval, 4.5-5.5 µm diameter, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Europe, Great Britain, North and South America, Australia, New Zealand.
HABITAT: Crowded often in fascicles on bark or decorticated dead branches or dead stipes of tree ferns.
Pilei grow in dense clusters, rarely solitary. At first globose, they soon become cylindrical. The exterior is covered with tortuous, aseptate, simple abhymenial hairs which later may disappear though some may remain near apices. The subiculum is arachnoid, delicate and often difficult to detect unless specimens are examined under a dissecting microscope. Spores vary in size and shape; when first formed, walls are relatively thick, but as spores mature walls become thinner. In a previous paper (1953b, p. 176) I listed "Solenia" fasciculata as a synonym of S. candida . W. B. Cooke has advised that the two may be separated by the abhymenial hairs, those of the former being filiform and encrusted, of S. candida delicate, naked, and branched near apices. In other particulars they appear to be similar, save that pilei of L. candida are seldom crowded into fascicles.
TYPE LOCALITY: Europe.
