''Microstoma floccosum'' is a species in the Sarcoscyphaceae family of cup fungi. It is recognizable by its deep funnel-shaped, scarlet-colored fruiting bodies bearing white hairs on the exterior. Found in the United States and Asia, it grows on partially buried sticks and twigs of oak trees. == Description ==
The diameter of the cup- or funnel-shaped fruiting bodies is in diameter; the margins of the cup are curved inwards when young. Both the interior and exterior surfaces of the cup are scarlet red. The exterior surface is covered with stiff white hairs. Details of the hair structure may be seen with a magnifying glass: they are up to 1 mm long or more, translucent, thick-walled, rigid and more or less sword-shaped with simple, sharply diminishing bases. They are connected to the fruiting body at the junction of internal tissue layers called the medullary and ectal excipulums. When the hairs come in contact with an alkali solution of 2% potassium hydroxide, the thick walls of the base of the hair first swell in size and then dissolve, releasing the contents of the internal lumen.〔 The stem is cylindrical, and about long by 1–2 mm thick.
