Genus: Stemonitis

Brief Description: [See More | Edit]

SPORANGIA:. Sporangia narrowly cylindrical, in dense and often large clusters 10 to 50 mm in diameter, stalked, usually curved, rusty brown,total height 7 to 20 mm. With .individual Sporangium are 0.2 to 0.3 in diameter.
STALK: black, 3 to 7 mm. high, rising from a membranous hypothallus.
COLUMELLA: ending below the summit of the sporangium.
CAPILLITIUM: with a smooth and usually close surface-net, connected with the columella by few stout branches, and composed of rather firm threads bounding rounded meshes, which are usually small although varying in size.
NOTES: Off all the Stemonitis this is the most common. As with many members of this genus the plasmodium is able to find its way through decaying wood this enables fruiting on relatively dry logs after merging from within the log were it is still most.
SPORES: Brown 5 to 7 µm in diameter and almost smooth (minutely punctuate).
PLASMODIUM: white, rarely pale yellow. HABITAT: On dead wood.

Taken from:

Plasmodium white. Sporocarps in tufts, 7-20 mm tall. Hypothallus membranous, brown, continuous under the tuft. Stalk 1.5-6 mm long, shining black, opaque. Sporotheca cylindrical, tapered around the apex and base, rust-coloured when fresh. Columella gradually tapered towards the apex of the sporotheca and flexuose apically and there merging into the capillitium. Capillitial internal net with c. 3 meshes over the radius, usually with expansions in the axils, pale brown, the surface net consisting of thin threads with angular meshes which are usually ca. 5-34 µm diam., almost without free ends. Spores very pale rosy-brown, 5.0-7.5 µm diam., with very fine pale warts seen by oil-immersion.
