Fig. 3
Sporocarps grouped or scattered, sessile. Sporotheca subglobose,
0.5–0.6 mm
diam., brownish black (65. br. Black). Hypothallus inconspicuous. Stalk absent. Peridium double, partially evanescent; outer layer dull, with dirt accumulated in surface, light yellowish brown (94. l. Ol Br); inner layer thin, translucent, pale yellow (89. p. Y) by transmitted light, inner surface warted; dehiscence irregular. Columella absent. Capillitium tubular, elastic, elateriform, yellow (83. brill. Y–84. s. Y) by transmitted light, without attachments to the peridium, tubules 2.6–3(–4) µm diam., flexuous, decorated with 3–4 smooth spirals, free ends short-pointed, 8–9 µm long, sometimes preceded by a 5–6 µm diam. swelling. Spores free, yellow (83. brill. Y–84. s. Y) in mass, yellowish (104. p. g Y–101. l. g Y) by transmitted light, subglobose, 14–15 µm diam., densely warted, wall thick, and with a large pale area.

Comments:
—First record for the Neotropics and
Peru
. It was found in branches of small shrubs associated with cryoturbed soils, and it represents one of the records at higher altitudes of
Myxomycetes
in the world. Morphologically, it resembles
Trichia contorta
(Ditmar) Rostaf. (1875: 259)
, but it is distinguished by the smaller spores, 11–14 µm diam.
vs.
14–15 µm diam. in
T. mirabilis
, and the length of the pointed free ends, 10–20 µm long
vs.
8–9 µm long in
T. mirabilis
.
