Summary
| Description |
English: Bipartite and tripartite cyanolichens. A ) In the bipartite cyanolichen Peltigera scabrosa the cyanobacterial symbiont (Nostoc) forms a continuous layer just below the upper cortex of the lichen thallus B) Nephroma bellum is another example of bipartite cyanolichens C) In the tripartite cyanolichen Peltigera aphthosa the Nostoc symbiont is restricted to wart-like cephalodia (shown magnified) on the upper surface of the thallus, while the green algal symbiont (Coccomyxa) forms the photobiont layer D) Nephroma arcticum is another example of tripartite cyanolichens. The large cephalodia of this species are internal, but clearly visible through the upper cortex of the hydrated thallus.
Nederlands: Bipartiete en tripartiete cyanolichenen. A) In de bipartiete cyanolichen Peltigera scabrosa vormt de cyanobacteriële symbiont (Nostoc) een doorlopende laag net onder de bovenste cortex van de korstmosthallus B) Nephroma bellum is een ander voorbeeld van bipartiete cyanolichenen C) In de tripartiete cyanolichen Peltigera aphthosa is de Nostoc symbiont beperkt tot wrat (vergroot weergegeven) op het bovenoppervlak van de thallus, terwijl de groene algensymbiont (Coccomyxa) de fotobiontlaag vormt. D) Nephroma arcticum is een ander voorbeeld van tripartiete cyanolichens. De grote cephalodia (wratten) van deze soort zijn intern, maar duidelijk zichtbaar door de bovenste cortex van de gehydrateerde thallus. |
