Filimentous, byssoid, leprose, and other lichens do not have a cortex ( are ecorticate ).
2.
Filamentous, byssoid, leprose, gelatinous, and other lichens do not have a cortex, which is called being ecorticate.
3.
The floating balls are sometimes enclosed in a loose subiculum, with a whitish surface that is byssoid ( consisting of fine threads ).
4.

5.
Byssoid lichens are of two types, those where the cottony structure is dominated by photobiont filaments ( e . g ., " coccoid photobionts among them.
6.
The peridium ( the outer protective tissue layer ) is 18 30 ?m thick, byssoid, and made of clamped hyphae typically 2.5 4 ?m in diameter intertwined with dendrophyses ( irregularly branched cystidia ) 1 ?m in diameter.
