Ciri dan struktur

The cap of L. fallax is 2 – 9 cm wide, ranging in shape from convex to nearly flat with a small umbo, expanding to plane or becoming shallowly depressed, with or without the umbo. The margin (cap edge) is even or scalloped. The cap surface is dry and velvety, finely wrinkled over the center, azonate (without concentric lines), and dark sooty brown to blackish. The gills are attached to subdecurrent (running shortly down the length of the stem), narrow, crowded, not forked, white at first, and become creamy buff with age. The edges of the gills are brown like the cap, and slowly stain vinaceous (redwine-colored) when bruised. There are several tiers of lamellulae (short gills that do not reach the stem) interspersed among the full-length gills. The stem is 2.5 – 8 cm long, 5 – 15 mm thick, nearly equal in width throughout, dry, solid, unpolished or velvety, and a paler brown than the cap. The flesh is thin, brittle, staining pale vinaceous. The odor is not distinctive, and the taste mild or faintly acrid. The latex is copious, white on exposure, unchanging, slowly staining flesh and gills vinaceous. The spore print is yellowish-white. The edibility of the mushroom is unknown. The species is one of several brown to nearly black milkcaps that are, according to David Arora, "notable for their beauty, and therefore likely to attract the attention of even the casual collector". The variety Lactarius fallax var. concolor is nearly identical to the main species in appearance and distribution, but has gill edges that are colored like the gill face. The spores are spherical, and ornamented with warts and ridges that form a partial reticulum (a net-like pattern of lines) with prominences up to 2 μm high.

Habitat dan peran ekologis

Tubuh buah L. fallax tumbuh terpecah-pecah dan dikelompokkan bersama di tanah, atau di atas batang konifer yang sangat busuk di daerah alpine di bawah konifer berdiri. They are juga ditemukan di hutan pohon cemara. They are cukup umum, dan biasanya ditemukan antara August and Oktober. L. fallax terbagi di barat Kanada Serikat States and, dengan rentang utara yang membentang ke Alaska; rentang timur dibatasi di timur oleh Dataran Tinggi. Field observations menunjukkan bahwa jamur dapat membentuk ektomikoriza asosiasi dengan Tsuga heterophylla. Hesler and Smith noted bahwa varietas warna konkolor yang dominan di antara spesies Fir.

Ringkasan sumber

Lactarius fallax, commonly known as the velvety milk cap, is a species of fungus in the family Russulaceae. Its fruit bodies are medium-sized, with velvety, brown to blackish caps up to 2 – 9 cm in diameter bearing a distinct pointed umbo. The caps are supported by velvety stems up to 8 cm long and 1.5 cm thick. The mushroom oozes a whitish latex when it is cut, and injured tissue eventually turns a dull reddish color. The eastern North American and European species L. lignyotus is closely similar in appearance, but can be distinguished by its differing range.

Ekologi sumber

The fruit bodies of L. fallax grow scattered to grouped together on the ground, or on very rotten conifer logs in alpine areas under standing conifers. They are also found in spruce forests. They are fairly common, and typically found between August and October. L. fallax is distributed in the western United States and Canada, with the northern range extending to Alaska; the eastern range is bounded on the east by the Great Plains. Field observations suggest that the fungus can form ectomycorrhizal associations with Tsuga heterophylla. Hesler and Smith noted that the variety concolor was prevalent under species of Fir.
