Physical Description

Genus Macbrideola:

Sporocarps small, stipitate, globose to ovate. Stalk translucent, hollow (trapped air is often seen in liquid mounts). Columella usually present. Peridium fugaceous or persistent. Capillitium present or absent.

Species Macbrideola argentea:

Scattered or solitary, 0.5-1.0 mm tall. Stalk slender, c. 75%-80% of the total height, attenuate upwards, black in reflected light, red-brown below and opaque above by TL, indistinctly longitudinally striate below, hollow. Sporotheca globose, shining silvery and c. 0.1 mm diam. Peridium persistent, when dehisced leaving a collar round the stalk at the base of the sporotheca, membraneous, colourless, smooth. Columella reaching 20%-50% of the sporotheca, where it splits into two or three branches and merges with the capillitium. Capillitium arising from the apex of the columella, rather lax, slender, brown, dichotomously branched 3-5 times, with few or no anastomoses, and many, mostly c. 10 µm long, slender attenuate ultimate branchlets. Spore-mass dark brown. Spores pale grey, 7-8.5 µm diam., densely pale-verruculose and with small groups of larger, darker warts.
