　Description： Fructification sporangiate, stipitate, gregarious or solitary, sometimes 2 connected at the lower part of stalks forming a cluster, erect, 0.77 ~ 1.09 mm in total height. Sporangia obovoid, 0.38 ~ 0.58 mm in diameter, dark reddish brown to purplish brown, covered with amorphous matters except at pale yellow bands which arranged in a reticulate pattern on the upper part. Peridium double, the outer layer opaque, dark as nut brown, closely appressed to the inner layer, the inner layer membranous, translucent, appearing as reticulate yellow bands, dehising along the bands. Stalk blackish, cylindrical. Hypothallus membranous, colorless. Capillitium composed of yellow elaters, 3-4 μm in diameter, bearing 4-5 spirals with scattered long or short spines in 2-6 μm in length, free ends obtusely pointed with long spines of 7-11 μm long at the end, or forking into 2-3, about 20 μm. Spores dull orange-yellow in mass, pale grayish yellow by transmitted light, globose to subglobose, densely warted, tips of the warts mushroom-like in optical section, 7 ~ 11 μm (mostly 7 ~ 8.5 μm) in diameter.

　Note： The fruiting body of our specimen are smaller with smaller spores as well. Nevertheless, those of our largest size fall in the range (sporangial diameter: 0.4-0.7 mm, total height: 1-2.6 mm) as described in the references (Nannenga-Bremekamp, 1991; Martin and Alexopoulos, 1969 ). Other characters agree very well to the taxon Trichia erecta. In outer appearance this taxon resembles Trichia botrytis, but the spiny elaters with much shorter and obtusely pointed ends are distinctive characters separating it from the latter, Trichia botrytis.
