Umthombo we-vanillin, i-syringic aldehyde, i-dimethyl sulfoxide, i-Lignin (i-Dealkaline) ingaba i-extender yamapulasitiki e-phenolic, ukuqinisa irabha (esp yezicathulo zezicathulo), njengesengezo sodaka lwamafutha, ukuzinzisa ama-emulsions e-asphalt, ukwehlisa amaprotheni.

Ukubonakala okuphelele kwama-lichens kuchazwa ngokuthi i-crustose (enza uqweqwe oluncane futhi oluyisicaba ku-substratum), i-foliose noma i-fruticose (amafomu aqondile, amagatsha, afana nezihlahla). Ama-Lichens akhula kancane ukusuka kumamilimitha ambalwa kuya kumamitha amaningana unyaka ngamunye. Zizalana kakhulu ngokukhula kwe-apothecia noma i-perithecia, zakha ama-lichen amasha ekuhlumeni kwe-ascospores kuphela phambi komlingani we-algal lapho ukhunta lungekho khona.
Amakhemikhali acishe abe ngu-700, awawodwa kuphela ulele, asiza ulele ukuba luphile futhi avimbele ukuhlaselwa amagciwane, ezinye isikhunta nezilwane ezidla uhlaza.
Ulwelwe luyingxenye yemiphakathi ewuqweqwe lwenhlabathi futhi lusiza ukusimamisa inhlabathi, ikakhulukazi ezindaweni eziwugwadule. Ama-cyanolichens afaka isandla ekulungiseni i-nitrogen ku-ecosystem akhula kuyo. I-LicheGare isetshenziselwa ukuhlonza iminyaka yendawo (lapho zikhula khona) ngendlela, ebizwa ngokuthi i-lichenometry.
Ama-Lichens ayizinkomba zokungcola ngenxa yokuzwela kwawo okuhlukile ku-sulphur dioxide (SO2), i-nitrogen dioxide (NO2) ne-ozone, kanye nekhono lawo lokumunca nokuqongelela izinsimbi ezisindayo nama-radionuclides.
Izinto ezinjengama-pigment, ubuthi, ama-antibiotics, njll. zitholakala kuma-lichens, awusizo ikakhulukazi njengomthombo wamadayi (isibonelo, i-Roccella, ehlinzeka nge-litmus), imithi kanye namakha. Olunye ulele, njengolembu lwase-Iceland kanye nobulembu be-reindeer, busetshenziswa njengokudla ezindaweni zase-arctic.
