Specimens examined. PERU. Puno: Cabanilla , route PE-34A, km 253, 3950 m, 15°39′55” S, 70°28′43” W, 8 Oct 2012, on Azorella diapensioides leaf bases (mc, 4 Dec 2012, pH 6.04), dwb 3548, (pH 6.09), dwb 3559 .

Notes. Although these collections macroscopically agree with the description of T. subfusca , they have primarily small sporocarps, possibly because they developed in moist chamber culture. The elater tips by SEM are the same smooth short tips as illustrated by Rammeloo in “Icones Mycologicae 1985 pl.107”. However, they differ in that there are no partly smooth areas on one side of the spores, and the spores are slightly larger (13-15 µm in diameter) but within the range of the description. The spore ornamentation by SEM is with pila, like the isotype, but sometimes with tiny warts on the epispore between the pila, approx 0.8 µm tall.
