Stemonitis axifera: The Ultimate Mushroom Guide
About The Stemonitis axifera Mushroom
Stemonitis axifera is a species of slime mold. It fruits in clusters on dead wood and has distinctive tall reddish-brown sporangia, supported on slender stalks. The erect, stalked cylindrical sporangia are arranged into bundles or clusters. Each sporangium is supported by a thin, shining, black stalk. The bright rusty brown color of mature sporangia lightens to a pale brown after the spores have been dispersed.
This slime mold fungus requires about 20 hours to finish making its fruit bodies. Of this, eight hours are needed for induction of the sporangia and the development of the stalk and the columella, six hours more for the sporocarps to produce pigment and mature, and an additional six until the spores are discharged.
