Stemonitis axifera is a species
of slime mold, and its fruits in clusters on dead wood, and has distinguishing
tall reddish-brown sporangia, supported on slender stalks. This species was
first described as Trichia axifera by Jean Baptiste François Pierre Bulliard in
1791. Thomas Huston MacBride transferred it to the genus Stemonitis in 1889.
Stemonitis fasciculata and Stemonitis smithii are synonyms. It requires almost
20 hours finishing making its fruit bodies. Out of this 8 hours are required
for induction of the sporangia and the development of the stalk and the
columella, 6 hours more for the sporocarps to yield pigment and mature, and an
additional 6 hours the spores are discharged. The slime mold grows on decaying
wood when the fruit bodies contain of milky white sporangia, they are a favored
food source for Philomycus slugs.
