apiculus

Basidiospores 8.55-11 x 4.5-6 um, Q= 1.8-1.84 or [greater than or equal to] 1.8, elliptical with prominent apiculus, rounded at the distal end, smooth to poorly ornamented; yellowish brown to brown, with oily drops, highly dextrinoid (deep reddish brown) in Melzer's reagent.

Basidiospores 8.8-9.4 x 3.8-5.0 [micro]m, ellipsoid to subcylindrical, somewhat tapering towards the apiculus, sometimes slightly concave at the adaxial side, thin-walled, smooth, acyanophilous, inamyloid, with oily contents.

Antennae dark brown with the apiculus pointed and hooked, red brown ventrally.

Castniid moths are medium to large in size, from 20 to 110 mm; they are related to Cossidae and Hesperiidae, the distal portion of the antenna is similar to that of the Hesperiidae with a club and apiculus and the presence of three cubital veins on the wings.

Basidiospores (5-)6-7(-8) x (3-)3.5-4.5(-5) x 3-4 [micro]m, narrowly subellipsoid, oblong ellipsoid or obscurely subrhomboid in face-view, subellipsoid in side-view, thin-walled, wall 0.5-0.8 [micro]m thick, pale to dark yellowish-brown, with a truncate germ pore, and a short and acute apiculus. Basidia (13-)(15-)(20-)22-29 x (4-) (5-) 6-7 [micro]m, 4-spored, clavate or subvesiculose-subcylindric, with a middle constriction, hyaline.

Relative lengths of antennomeres: 11-10-64-45-44-44-44-43-39-37-35-33-32-28-23-22; apiculus of distal flagellomere ca 0.2x article length.

Stamens included; filaments complanate, lilac toward the apex, the antepetalous ones adnate to the petals for 6-8 mm, the antesepalous ones free; anther base obtuse-sagittate, apex apiculate, apiculus nigrescent, dorsifixed above the base at 1/3 of its length; pollen globose, diporate, exine psillate; stigma conduplicate-spiral, ellipsoid-capitate, lilac-purple, margins crenulate-lacerate; ovary obconic, trigonous, 8-9 mm long, 6-7 mm in diameter at the apex, white, glabrous, bearing inconspicuous longitudinal sulcus; placentation apical; ovules shortly caudate; epigynous tube inconspicuous, ca.

Meanwhile, an apiculus is formed on the top of each anther (Figs.

2d) is awned and the lemma and palea were covered by spiny trichomes and lignified papillae, and the apiculus presented abundant large prickle trichomes in the distal end of the palea (Fig.

Basidiopores 7.5-9 x 7-8.5 um, globose to sub globose, reticulated, reticulum complete, with prominent apiculus. Basidia 35-60 x 10-12 um, clavate to clylinderical, thin-walled, 4-spored.

20 in number, subcoriacous, suberect-arcuate, forming a broad funnilform rosette; sheaths broadly elliptic, 13-14 x 10-11 cm, greenish toward the apex, subdensely brown lepidote on both sides, strongly nerved with conspicuously castaneous nerves, coarsely spinose at extreme apex; blades sublinear-lanceolate, narrowed toward the base, 25-60 x 5-6 cm, sparsely and inconspicuously white-lepidote to glabrescent, green to reddish at apex and along the apical margins, with sparse and irregular darker green spots, apex acute and distinctly apiculate, apiculus 3-4 mm long, rigid, margins densely to subdensely spinose, spines subspreading, triangular, castaneous toward the apex, the basal ones ca.
