|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
|
poricidal |

Forming one or more apertures in the exterior wall, usually apically or sub-apically, through which the contents pass to the outside. |
|

FEATURE |
|
A small, rounded depression. |
|
spheric(al) |
= globose, globular, orbicular, rotund, spheroid(al) |
solid shape |
|

= spire-shaped |
solid shape |
|
Attenuate-spiral in three dimensions, the coils contiguous or not. |
|
infrabracteal |
|
insertion |
|
Upon the axis directly below a bract insertion. |
|
tetrad scar |
|
FEATURE |
|
A surficial ridge or angle resulting from coherence with other spores produced from the same mother cell. |
|
lentiginous |
= dusty, lentiginose |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also pulverulent (granuliferous, powdery), which is not clearly distinct in its application. |
|

= one-sided |
orientation |
|
Disposed or directed toward one side only. |
|
acicular 1 |
|
plane shape |
|
Very slenderly elongate, widest near the middle, and gradually attenuate to an acute apex and a blunter base; like the lateral outline of a needle. |
|
blunt 2 |
= obtuse |
base |
|
Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
|
needle-shaped |
= acerose, acicular |
solid shape |

|
ensate |
= sword-shaped |
plane shape |
|
Elongate and moderately slender, broadest at the base and gradually attenuate to a short, more strongly attenuate, acute apex; like the outline of the lateral face of a broadsword blade. |
