Cortinarius is a sturdy, hardy genus preferring northern latitudes and autumnal months, though several of its species grow as far south as Alabama, and one, a new species described by Professor Peck, is found on the Helderberg mountains in May. The genus contains many species, most of which produce in great numbers, yet being woods-growing, and coming as they do when leaves are falling, they are often missed because of their similarity to their surroundings. Heretofore, less than a dozen species have been reported as eaten. This number is now doubled. While several species are bitter and others equally unpleasant, not one has been accused of harm. It is highly probable that other varieties than those herein given will prove equally acceptable as food. I have tested all I have found in sufficient quantity to warrant passing judgment upon them. The genus does not contain as many species of superior excellence as other fleshy genera of like numbers. The flesh is frequently dry and of a strong woody or musky flavor, which it does not lose in cooking. The stems are seldom cookable. All can be fried in butter, but cut in small pieces and well stewed, or stewed and served in patties, or made into croquettes are certain ways of keeping them in palate memory. ANALYSIS OF TRIBES. PHLEGMACIUM (_Gr_—shiny or clammy moisture). Page 308. Pileus viscid. Stem firm, dry. Veil partial, cobweb-like. _A._ CLIDUCHII (_Gr_—holding the keys—the typical subdivision). Page 308. Partial veil as a ring on the upper part of the stem which is equal or slightly expanded above. Not distinctly bulbous. * Gills pallid then clay-colored. ** Gills purplish then clay-colored. _B._ SCAURI (_Gr_—club-footed). Page 310. Bulbous. Bulb depressed or top-shaped, with a distinct margin caused by the pressure of the pileus before expansion. Veil generally ascending from the margin of the bulb. Gills somewhat sinuate. * Gills whitish then cinnamon. ** Gills blue then cinnamon. *** Gills brownish-white then cinnamon. MYXACIUM (_Gr_—mucus). Page 313. Universal veil glutinous. Pileus and stem viscid. Stem slightly bulbous. Gills adnate. INOLOMA (_Gr_—a fibrous fringe). Page 314. Pileus dry, not hygrophanous or viscid, covered at first with innate silky scales or fibrils, becoming smooth. Veil simple. Pileus and stem fleshy, rather bulbous. * Gills violaceous, then cinnamon. ** Gills pinkish-brown, then cinnamon. *** Gills yellow, then cinnamon. DERMOCYBE. Page 320. Pileus thin, equally fleshy, at first silky with a fine down, becoming smooth when adult. Not hygrophanous, but flesh watery when moist or colored. Stem equal or larger above, externally rigid, elastic or brittle, internally stuffed or hollow. Veil single, thread-like. TELAMONIA. Page 323.
