Pleurocystidia are absent but the clavate
, filamentous, subutriform, saccate and fusoid-ventricose cheilocystidia are striking features of this variety.
, swollen at the median region and with slightly pronounced constriction between the median region and the apex.
Conidiogenous cell clavate
, polyblastic, discrete, three in number and each cell with two or three denticles at the apex which bear the conidial in chains with isthimi.
Representatives of the genus Ischnocolus can be distinguished from all other Ischnocolinae genera by the clavate
(club-shaped) tarsal trichobothria, with small barbs on the surface, that are arranged in a short median apical row and by the maxillae having a lighter colour on the prolateral edge on the ventral surface than on the retrolateral edge, in both live and preserved specimens.
5 mm long, bright red, clavate
to narrowly pyriform, smooth.
The appressoria developed in different positions on the conidia and presented distinct shapes, including spherical, irregular, lobed or clavate
5-12 [micro]m Basidia clavate
, two sterigmata, 40-85 x 6-9.
gracilis Transversal Absent Smooth, Axillary Clarke, 1882 clavate
from pedicel L.
can be distinguished by the presence of two spines on the intermediate appendages, the shape of tergum X, which is clavate
apically, the wide 2nd article of inferior appendages, and the smaller number of phallic spines.
First and second palpomere of maxillary palp cylindrical, subequal in length and shape, third one slightly more than twice as long as first; fourth palpomere half as long as third, with narrower basis, fifth slightly clavate
, length equal to sum of second and third palpomeres.
Posterolateral angles of dorsal external laterotergites II to III without protruding, IV to VI slightly protruding, VII forming an obtuse angle; lateral border of connexival segments V to VII slightly concave, posterior margin of segment VII substraight; paratergites clavate
, as long as one-second length of pygophore; glabrous area faint (Figs.
Oosporangia are 160-220 [micro]m in size, clavate
form, thick, and with a smooth wall.
