It grows on stumps, roots in the ground, trunks and earth heavily charged with wood matter. I have found it in every month of the year. The heavier crop appears in September, October and November, and lasts until long after heavy frosts. Then sporadic clusters spring up wherever the winter sun gives them encouragement. It sometimes does considerable damage to the tree so unfortunate as to be its host. It begins its growth upon some injured or decayed spot and by continually insinuating itself under the surrounding bark it, by its mycelium and growth, pries the bark away from the wood until the tree is entirely denuded. It is a valuable species, not only on account of its continuous growth, but because of its plentifulness and excellent substance. ** _Gills very narrow, closely crowded._ =C. con´fluens= Pers.—=Pileus= ¾-1½ in. broad, thin, tough, flaccid, convex or nearly plane, obtuse, rarely somewhat umbonate, glabrous, hygrophanous, reddish grayish-red or reddish-brown and often striatulate on the margin when moist, pallid, whitish or grayish when dry. =Lamellæ= narrow, crowded, free, whitish or yellowish-gray. =Stem= 2–5 in. long, 1–2 lines thick, equal, cartilaginous, hollow, clothed with a short dense somewhat pulverulent whitish pubescence or down. =Spores= minute ovate or subelliptical, slightly pointed at one end, 5–6×3–4µ. Among fallen leaves in woods. Common. July to October. The plants commonly grow in tufts, but sometimes in lines or arcs of circles or scattered. They revive under the influence of moisture and thereby indicate an intimate relationship to the genus Marasmius. The pileus varies much in color, but commonly has a dull reddish or russety tinge when moist, sometimes approaching bay-red. It fades in drying and becomes almost white or grayish-white, but sometimes the center remains more deeply colored than the margin. The stem is commonly rather long in proportion to the width of the pileus. Occasionally it is somewhat flattened either at the top or throughout its entire length. Sometimes the stems become united at the base which union is suggestive of the specific name. _Peck_, 49th Rep. West Virginia, New Jersey, Pennsylvania, _McIlvaine_. July to frost. The caps of C. confluens are of excellent substance and flavor. Their quantity makes up for their small size. I have gathered them 2 in. across, but their average size is about 1 in. They dry well.
