Comatricha lurida Lister

Sporocarps stipitate, brown purple, up to 1.5 mm high, isolated and forming small colonies. Sporotheca globose.

Peridium remaining and forming a collar at the base of the sporotheca. Stalk cylindrical, widened at the base, with a length of 0.8 mm, approximately twice the diameter of the sporotheca. Columella cylindrical, reaching half the height of the sporotheca. Capillitium originating along the columella. Apex of the columella with thick branches, dividing into thinner and flexuous branches but without forming a defined network and with free ends at the end. Spores globose, 8.3–10.6 × 8.3–10.5 μm, av. 9.5 × 9.4 μm, Q av = 1 (n = 25), purplish-gray, with marked wrinkles. Under SEM, the spore ornamentation is formed by thick baculae of different size and irregular distribution, which sometimes are joined and form short ridges (figs. 3a–g).
