Lichens too :o} ?

Hope I'm not a nuisance in asking if Lichens could also be added in the Category list ?

Can we combine mosses & lichens into one category?

Sure! That would be fine. Thanks!

Best not to - mosses are more closely related to flowering plants, than they are to lichens. They're in different kingdoms!

Resin

That's an excellent point, and I'm red-faced I didn't raise that objection myself. (I knew there was a reason we had shied away from lichens in PlantFiles in the past ;o)

Resin, you made a good point! But then do Lichens belong to the same kingdom as the Fungi ? I know that these are not considered to be plants!

Lichens are a symbiotic combination of alga and fungus, so in theory, they fall into two different groups in one go. Not sure how their formal classification works out! Try checking the Tolweb site:

What could be grouped with mosses is liverworts, they are fairly close (I think! - best check!!)

Resin

Thanks Resin, I do understand (feel intuitively) that liverworts are closer to the plant kingdom...and not the lichens I feel are more closely related to the fungi world...

But, alas I think the scientifical nomenclature used in the sites is beyond me...
