Taxonomy

Notes:

Name Status: Accepted Name. Latest taxonomic scrutiny: Kirk P.M., 14-Sep-2005

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 declinata:

Sporocarps solitary to scattered, 0.2-0.35 mm total height. Sporothecae globose, usually smooth, silvery, bronze, or gold-coloured to dark purplish brown, often with metallic reflections and somewhat iridescent, 0.1-0.2 mm diam. Peridium membranous, persistent, the inner surface marked with dark papillae, the base persisting as a small collar. Stalk erect, hollow, pale at the base, becoming progressively darker red, the upper portion nearly black. Columella dark, reaching to near the apex of the sporotheca. Capillitium arising from the columella apex as 2-4 primary branches, lax, consisting of purplish brown threads arranged ± at right angles to the columella when short or, when longer, tending to arch downwards and with the tips frequently attached to the peridium. Spore-mass brown. Spores distinctly and unevenly echinulate, 7-8 µm diam. This sp. has many similarities with M. scintillans var. scintillans, especially when the capillitium is reduced.
