ba·sid·i·um

, pl.

ba·sid·i·a

(ba-sid'ē-ŭm, -ă),
A cell or spore-bearing organ usually club-shaped that is characteristic of the Basidiomycota. It bears basidiospores externally after karyogamy and meiosis. It is composed of a swollen terminal cell situated on a slender stalk, and gives rise to slender filaments (sterigmata), usually four in number, from the ends of which the basidiospores are developed.

Basidia 24.5-35 x 5.5-6.5 [mu]m, cylindro-clavate to clavate, tetrasporic, hyaline (Fig.
Basidia 18.0-20.2 x 5.8-6.8 [micro]m, clavate, 4-sterigmate, with basal clamp and oily contents; sterigmata up to 4.4 [micro]m long.
Basidia 16.0-28.0 x 5.6-6.8 [micro]m, clavate, 4-sterigmate, with basal clamp, with or without oily contents; sterigmata up to 4.8 [micro]m long.
Germination with phragmobasidia; often two-celled parts of the basidia separate from the rest of the basidium, and plasma left in the teliospore germinates again; basidial cells develop basidiospores or hyphae.
Hymenium thickening; basidia 23-28 X 6-7 [micro]m, clavate, clamped, yellowish and somewhat refringent under phase contrast; contents homogeneous or with minute granules or guttules, especially proximally; sterigmata 4, slender, more or less straight.
For morphoanatomical characterization of ectomycorrhizae, terminologies of Agerer (1991, 2006) were followed and sporocarps were analyzed macroscopically (color, lamellae, shape etc.) and microscopically (basidia, basidiospores, cystidia etc.) following Reid (1984) methodology.
The measurements of spores, basidia, cystidia and sterigmata were taken and drawings were made with the aid of a camera lucida.
Size dimensions were determined for 25 basidiospores, 20 basidia, 20 cystidia, from each basidioma.A sample from a dried specimen of each species was ground in liquid nitrogen and placed in 2% CTAB buffer and DNA was extracted using Porebski et al.
Microscopic examinations (spore, hyphae, basidia and cystidia) were performed using Leica DM LS2 microscope.
