 Description: Fructification sporangiate, gregarious to crowded, 1.5-2.5 mm in total height. Sporangia stipitate, turbinate to obpyriform, orange-citrine to Buckthorn brown, 0.5-0.9 mm in diameter. Peridium iridescent, aniline yellow, thin and delicate above, dehiscent at the top, below thicker and persisting as a deep cup. Stalk olivaceous brown below, paler above, shining, filled with spore-like spherules, 0.4-1 mm long. Capillitium redish brown (much darker than spore mass), consisting of simple or scarcely branched elaters, elaters smooth, bearing 3-5 spiral bands, 4.0-4.5 μm in diameter at the middle part, gradually tapering to form a long, slender end, brownish yellow by transmitted light. Spores yellow in mass, rounded, (7.5-) 8.0-10.0 (-11.5) μm in diameter, or ovoid in few and 8.0 x 10.0 μm, banded reticulate or warted reticulate.

 Note: Some fruitings may resemble Hemitrichia clavata in the field, but the nature of the capillitium distinctly separate Trichia decepiens from H. clavata. Other characteristics that separate this species from other stipitate Trhchia are the iridescent, aniline yellow peridium, the calyculus, and the stalk filled with spore-like cells. It was listed as a species new to Taiwan without any description for the species (Wang et al., 1981).
