Fig. 6. Ring narrow, scarcely perceptible above the middle of the stem; remnants of the veil adhering to the margin of the cap as a fugacious web. Fig. 7. Ring generally wanting--_Tricholoma nudum_. Remnants of the veil seen on the margin of the cap. Fig. 8. Remnants of the veil appearing on the margin of the cap as a fringe, and particularly on the stem as a mere fibrillose zone of a darker color as in the _Cortinarii_. Fig. 9. Plant exhibiting the cortina unbroken, the extremities of its delicate arachnoid threads attached to cap and stem, respectively. Fig. 10. Section of a Russula, in which genus the ring is always wanting; veil none. [Illustration: Plate F. THE NORRIS PETERS CO., PHOTO-LITHO., WASHINGTON, D. C.] PLATE F.

Hymenophore continuous with the stem, veil woven into a fugacious web, which adheres to the margin of the pileus. Gills adnate or sinuate; spores brownish purple, sometimes intense purple, almost black.--M. C. Cooke. This subgenus has been divided into the following five groups: 1. Fasciculares.--Pileus smooth, tough, bright colored when dry, not hygrophanous. Examples, Ag. (Hypholoma) _sublateritius_ and Ag. (Hypholoma) _fascicularis_. 2. Viscidi.--Pileus naked, viscid. Example, Ag. (Hypholoma) _oedipus_. 3. Velutini.--Pileus silky, with innate fibrils. Example, Ag. (Hypholoma) _velutinus_. 4. Flocculosi.--Pileus clad with floccose superficial evanescent scales. Example, Ag. (Hypholoma) _cascus_. 5. Appendiculati.--Pileus smooth and hygrophanous. Example, Ag. (Hypholoma) _Candollianus_. The species are not numerous. They are generally either gregarious or caespitose, and are often found in clusters upon tree stumps, or springing from the buried roots of stumps. A few species are found in short grass in open places; but few are recorded as edible, and one, H. _fascicularis_, has been classed as deleterious by Berkeley, Cooke, and some of the earlier authors. I find, however, no authenticated case of poisoning by this species, and, indeed, have as yet found no species of Hypholoma which could be satisfactorily identified as H. fascicularis.
