1868 J. D. Dana Syst. Mineral. (ed. 5) 805 The name Trichite..is applied by Zirkel..to microscopic capillary forms, often curved, bent, or zigzag,..opaque and black or reddish-brown, of undetermined nature, which he detected in some..glassy..volcanic rocks.

1879 F. Rutley Study of Rocks x. 162 Trichites..are minute elongated bodies resembling small hairs or fibres.

2. Zoology. A name for extremely fine siliceous fibres found in certain sponge-spicules, or for such spicules themselves: see quot. 1887. Also attributive.

1887 W. J. Sollas in Encycl. Brit. XXII. 418/1 (Sponges) A curious group of flesh spicules are the trichites. In this group silica..forms within the scleroblast a sheaf of immeasurably fine fibrillæ or trichites... The trichite sheaf may be regarded as a fibrillated spicule.

1890 Cassell's Nat. Hist. VI. 322 In other forms, the trichites grow radiately outward.., and becoming thickened with age, produce a trichite-stellate, or, if they are very numerous, a trichite-globate or globate spicule.
