hroughout.

2. _Granulations or Blotchings_:

Finely granular.

Coarsely granular.

Grumose: Coarser than the preceding, with a clotted appearance, and
particles in clustered grains (Fig. 145, a).

Moruloid: Having the character of a mulberry, segmented, by which the
colony is divided in more or less regular segments (Fig. 145, b).

Clouded: Having a pale ground, with ill-defined patches of a deeper tint
(Fig. 145, c).

[Illustration: FIG. 146.--Types of colonies: a, Reticulate; b,
gyrose; c, marmorated.]

3. _Colony Marking or Striping_:

Reticulate: In the form of a network, like the veins of a leaf (Fig.
146, a).

Areolate: Divided into rather irregular, or angular, spaces by more or
less definite boundaries.

Gyrose: Marked by wavy lines, indefinitely placed (Fig. 146, b).

Marmorated: Showing faint, irregular stripes, or traversed by vein-like
markings, as in marble (Fig. 146, c).

Rivulose: Marked by lines like the rivers of a map.

Rimose: Showing chinks, cracks, or clefts.

[Illustration: FIG. 147.--Types of colonies--curled.]

4. _Filamentous Colonies:_

Filamentous: As already defined.

Floccose: Composed of filaments, densely placed.

Curled: Filaments in parallel strands, like locks or ringlets (Fig.
147).

(E) ~Edges of Colonies.~--

Entire: Without toothing or division (Fig. 148, a).

Undulate: Wavy (Fig. 148, b).

Repand: Like the border of an open umbrella (Fig. 148, c).

Erose: As if gnawed, irregularly toothed (Fig. 148, d).

[Illustration: FIG. 148.--Edges of colonies: a, Entire; b, undulate;
c, repand; d, erose.]

Lobate.

Lobulate: Minutely lobate (Fig. 149, e).

Auriculate: With ear-like lobes (Fig. 149, f).

Lacerate: Irregularly cleft, as if torn (Fig. 149, g).

Fimbriate: Fringed (Fig. 149, h).

Ciliate: Hair-like extensions, radiately placed (Fig. 149, j).

Tufted.

Filamentous: As already defined.

Curled: As already defined.

[Illustration: FIG. 149.--Edges of colonies: e, Lobar-lobulate; f,
auriculate; g, lacerate; h, fimbriate; i, ciliate.]
