The North American Slime-Moulds A Descriptive List of All Species of Myxomycetes Hitherto Reported from the Continent of North America, with Notes on Some Extra-Limital Species The species may be known by the thin and comparatively smooth peridium and yellow flocci. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The spines soon fall from the upper part of the peridium, leaving the inner peridium with a smooth purplish-brown surface, often slightly scarred by the base of the spine. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth Breaking away at maturity in a circumscissile manner, the lower part is held fast to the ground, while the upper part remains attached to the inner peridium as a kind of cup. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The inner peridium, with the top part of the outer peridium attached, becomes loose and tumbles over the ground, the mouth being in the base of the plant as it grew. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The peridium is paler, smoother, though sometimes almost black, thin, ruptured irregularly. The North American Slime-Moulds A Descriptive List of All Species of Myxomycetes Hitherto Reported from the Continent of North America, with Notes on Some Extra-Limital Species This tribe is characterized by having a stalk continuous with the apex of the peridium, forming an axis. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth Peridium obovate, nearly sub-turbinate, with a soft, delicate, velvety bark; yellowish; inner peridium smooth and glossy, opening by a small aperture. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The threads, or capillitium, which bear the spores proceed from the walls of the peridium and form the central columella. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The plant ripens in the fall and the thick outer peridium divides into segments, the number varying from four to twenty. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The plasmodium is pale pink, soon becomes buff when exposed in fruiting, finally pallid or somewhat livid, and is outwardly changed into the stout, tough peridium. The North American Slime-Moulds A Descriptive List of All Species of Myxomycetes Hitherto Reported from the Continent of North America, with Notes on Some Extra-Limital Species The characteristic of this plant is the verrucose inner peridium. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The peridium is turbinate, depressed above; the base short and obconic, or more elongated and tapering, or subcylindric, arising from a fibrous mycelium. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth Under a glass of low power it appears as though the peridium were densely covered with grains of sharp sand. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth Fleshy layer generally peeling off from the segments of the fibrillose layer but usually remaining partially free, as a cup at base of inner peridium. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth A rare and beautiful species, distinguished well by the small size, about .5 mm., by the thin iridescent peridium, as by the microscopic characters of the capillitial threads. The North American Slime-Moulds A Descriptive List of All Species of Myxomycetes Hitherto Reported from the Continent of North America, with Notes on Some Extra-Limital Species Notice the remains of a fleshy layer forming a cup at base of inner peridium, a point which distinguishes this species and which gives name to the species—triplex, three folds or apparently three layers. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth In Bovista the threads are free or separate from the peridium, but in Lycoperdon they arise from the peridium and also from the columella. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth Inner peridium sessile, globose, with a determinate fibrillose mouth. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth Inner peridium, subglobose, supported on several more or less confluent pedicels. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The netted capillitium and the evanescent peridium suggests Arcyria, but there are abundant free tips, and the threads are unmistakably spirally wound, especially in the large, handsome sporangia characteristic of the Mississippi valley. The North American Slime-Moulds A Descriptive List of All Species of Myxomycetes Hitherto Reported from the Continent of North America, with Notes on Some Extra-Limital Species The sporangia is very similar to that of S. fusca, cylindrical, peridium fugacious, exposing the reticulate capillitium, but instead of being dark-brown it is a yellowish or rusty-brown color.
