Umthombo we-vanillin, i-syringic aldehyde, i-dimethyl sulfoxide, i-Lignin (i-Dealkaline) ingaba yi-extender ye-phenolic plastics, ukuqinisa i-rubber (esp yezicathulo zezicathulo), njenge-oyile yodaka lodaka, ukuzinzisa i-asphalt emulsions, ukukhupha iiprotheni.

Ukubonakala ngokubanzi kwe-lichens kuchazwa njenge-crustose (yenza i-crust encinci kunye ne-flat kwi-substratum), i-foliose okanye i-fruticose (ethe tye, iifom ze-branched, ezifana nezihlahla).Ubulembu bukhula kancinane ukusuka kwiimilimitha ezimbalwa ukuya kwiimitha eziliqela ngonyaka.Zivelisa ngakumbi ngophuhliso lwe-apothecia okanye i-perithecia, zenza i-lichens entsha ekuhlumeni kwe-ascospores kuphela xa kukho iqabane le-algal apho ukungabikho kwefungus kuyafa.
Phantse iikhemikhali ezingama-700, ezifumaneka kwilyan kuphela, zinceda iileyi ukuba ziphile kwaye zithintele ukuhlaselwa ziintsholongwane, ezinye iifungi kunye nezilwanyana ezitya utyani.
I-Lichens zezoluntu olunoqweqwe lomhlaba kwaye zinceda ukuzinzisa umhlaba, ngakumbi kwiindawo ezisentlango.I-cyanolichens inegalelo ekulungiseni i-nitrogen kwi-ecosystem apho zikhula khona.I-LicheGare isetyenziselwa ukuchonga ubudala bomphezulu (apho zikhula kuwo) ngobuchule obubizwa ngokuba yi-lichenometry.
I-Lichens zizibonakaliso zongcoliseko ngenxa yobuntununtunu bokwahluka kwi-sulphur dioxide (SO2), i-nitrogen dioxide (NO2) kunye ne-ozone, kunye nokukwazi ukufunxa kunye nokuqokelela isinyithi esinzima kunye ne-radionuclides.
Izinto ezifana ne-pigments, i-toxins, i-antibiotics, njl njl. zifumaneka kwii-lichens, eziluncedo ngokukhethekileyo njengomthombo wedayi (umzekelo, i-Roccella, ukubonelela nge-litmus), amayeza kunye neziqholo.Obunye ubulembu obufana nobulembu base-Iceland kunye nobulembu be-reindeer, busetyenziswa njengokutya kwimimandla ye-arctic.
