For effective results, various stains (lactophenol and cotton blue, Melzer's reagent, congo red, etc.) were used to visualize different cellular structures such as hyphae,
basidia, and spores.
Basidia 23-33 x 6.5-7.5 [mu]m, clavate, tetrasporic, rarely mono- or bisporic, hyaline (Fig.
Basidia clavate, 4 spored, brown in KOH, 31.6-35.1 x 6.8-10 um.
Measurements for
basidia, basidiospores and cheilocystidia were made using an ocular micrometer.
is a large and heterogeneous assemblage of species in Agaricomycetes, kept together on the basis of generally large sized, smooth basidiospores and constricted
basidia, rich in both oil drops and hyphae with conspicuous clamps.
Taxonomy and phylogeny of yellow Clavaria species with clamped
basidia - Flavostellifera sp.
Also, the similar microscopic features, notably spore and
basidia shape and size, adds weight to the conclusion that the two species may be part of a complex (Table 1).
Basidia (13-)(15-)(20-)22-29 x (4-) (5-) 6-7 [micro]m, 4-spored, clavate or subvesiculose-subcylindric, with a middle constriction, hyaline.
Segundo BEDENDO (1995), os basidiosporos sao ovalados, unicelulares, uninucleados, hialinos, normalmente nao existem ornamentacoes e sao produzidos a partir da germinacao dos teliosporos, os quais dao origem a um pro-micelio (tubo germinativo) que se diferencia numa
basidia. No caso da familia Tilletiaceae, a
basidia e asseptada, e os basidiosporos sao formados em tufos, situados na extremidade da
basidia.
