Plate 12, figure 7

Trichomes densely aggregated, moderately straight, 4.8-5.2 p
diam., deeply constricted; cells subcylindrical to dolioform, about
2 times as long as the diameter, homogeneous, pale drab to
amber-colored, forming microscopic colonies irregular in shape
and size, but mostly membranaceous; heterocysts spherical, sub-
spherical to dolioform; 6.5-7.5 ¡j diam; spores dolioform to
broadly ellipsoidal, 7-8 n diam., 12-15 n long, wall smooth, 10-15-
catenate; tegument yellowish or amber-colored at maturity,
moderately firm.

Growing on earth about five kilometers south of Adjuntas,
no. 1665, type; in a small stream about five kilometers east of
