Matula and phialides In two series (
biseriate) Conidia Conidia, spherical, 2.0-3.0 [micro]m.
The vesicles were hemispherical in shape, small, globose and flattened at the apical part, and diameters ranging from 8.0-12.0 m, with uniseriate and
biseriate sterigmata.
Ascospores partially overlapping to
biseriate, fusiform, brown, with three or more transverse septa without longitudinal septa, mostly terete (cylindrical; frequently circular in section but narrowing to one end), mostly with a thick sheath.
Young or distal regions of wild rice adventitious roots have a stele with differentiating proto- and metaxylem, a cortex with an endodermis, a midcortex with thick cell walls in inner layers, developing schizolysigenous aerenchyma, an enlarged outer ring of cells (not part of the hypodermis), a distinctly
biseriate hypodermis, and an epidermis at 5 mm from the apex (Figure 1(a)).
Plant mass formed by entangled filaments, caespitose, sometimes isolate filaments or in small groups in the mucilage of other cyanobacteria; main filament and branches similar; filaments usually uniseriate, occasionally
biseriate, 10.0-11.0 [micro]m wide, irregularly T-branched, Y-false branching present; sheath thin, hyaline; trichomes constricted, sometimes not constricted, 8.0-10.0(-13.0) [micro]m wide; cells cylindrical to rounded, 10.0-12.0(-15.0) urn long; heterocytes intercalary or apical, 9.016.0 [micro]m long, (8.0-)10.0-12.0(-13.0) [micro]m wide.
Postocular setae
biseriate, primary row stronger than secondary row, primary row disclinate (out-curved), secondary row inclinate (in-curved).
Gynoecium with superior ovary, densely pilose, trilocular;
biseriate Seminal rudiments up to 12 per cavity; axile placentation, thin placentae; style simple, large and filiform; stigma simple, usually terminal, subcapitate.
Conidial heads ar
biseriate, and phialides are borne on metula.
Blackbrush also exhibit summer dormancy, with characteristics of revolute margins, uniseriate hypodermis,
biseriate epidermis, biracial palisade parenchyma, and intercellular air space in leaves; all of which are characteristics of leaves from sclerophyllous chaparral plants.
Conidiophores were light brown with hemispherical vesicles bearing metulae and
biseriate philalides on the upper half.
