ORDER VI. CARYOPHANALES

ni'ti.dus. L. adj. nitidus shining, glittering.

Cells very distinct, the length equal to the breadth of the trichome. Trichomes very long, transparent, usually grow in twos or fours, pointed at the origin, rounded at the termination, 5 by 2083 microns. Spore-like bodies, formed within the cells, are usually solitary, oblique, oval and amorphous, 2.0 by 3.5 microns.

Source: Found in the intestine of the milliped (Julus marginatus).

Habitat: Found in considerable quantity with a profusion of Enterobryus elegans from the mucous membrane of the posterior portion of the rectum of Julus marginatus.

4. Arthromitus batrachorum Collin, 1913. (Arch. Zool. Expér. et Gén., 51, 1913, 63.)

ba.tra.cho'rum. Gr. noun batrachus frog; L. gen.pl.noun batrachorum of frogs.

Cells colorless, granular, 2.0 to 3.0 by 3.5 microns. Trichomes are non-branching and grow indefinitely. At various places in the trichomes some cells are thicker than others, and occasionally debris is seen alongside the trichomes, resulting from the rupture thereof. Each cell has a spore, round to ellipsoidal, obliquely situated within the cell. At first the spores are quite small and stain intensely by cold staining techniques. Later the spores become more voluminous and, when completely mature, are no longer stained without heat. The sporulation of a given cell occurs independently of that of any other cell in the same trichome.

Source: Found in the rectum of a frog tadpole (Alytes sp.) and from the alimentary tracts of toad tadpoles (Bufo calamita).

Habitat: Found in the intestinal tract of amphibians so far as is known.

Genus II. Coleomitus Duboscq and Grassé, 1930.

(Arch. Zool. Expér. et Gén., 70, 1930, Notes et Revue, 28.)

Co.le.o.mi'tus. Gr. noun coleus sheath; Gr. noun mitus thread; M.L. mas.n. Coleomitus sheathed thread.

Long trichomes, divided by partitions. Bacillary elements in basal region. Ovoid or ellipsoidal spores in other parts of the trichome originate by transformation from these bacillary elements through sporoblasts.

The type species is Coleomitus pruvotii Duboscq and Grasse.

1. Coleomitus pruvotii (Duboscq and Grassé, 1929) Duboscq and Grassé, 1930. (Coleonema pruvoti (sic) Duboscq and Grassé, Arch. Zool. Expér. et Gén., 68, 1929, Notes et Revue, 14; Coleomitus pruvoti (sic) Duboscq and Grassé, ibid., 70, 1930, N. et R., 28.)

pru.vo'ti.i. M.L. gen.noun pruvotii of Pruvot; named for Pruvot.

Trichomes, with hyaline sheath, 1.3 microns wide, length variable, up to 320 microns. Bacillary elements are 3 to 4 microns long; elements up to 6 microns long with a chromatic granule or disc in the middle of the body also occur. Spores ellipsoidal, 0.8 to 0.9 by 1.7 to 2.0 microns, all containing an eccentrically placed granule of volutin.

Source: Found in the intestine of a termite (Kalotermes sp.) from the Loyalty Islands.
