Hi All,

Was poking around my Dad’s place and came across the old water well, deep in the undergrowth.

I noticed a liverwort growing below the surface. Could it be Riccardia chamedryfolia?

Excellent information as always, the tap water round here is very soft but I’ve tested this well and the GH/KH was surprisingly high.

I found this growing on the brickwork of a canal lock in Staffordshire. Sounds likely to be the pellia you describe. Is it an aquatic species or just likes wet spots near water?

Hi all,

The Hart's-tongue fern (Asplenium scolopedrium) and Herb Robert (Geranium robertianum) are plants you would associate with base rich conditions, so I guessed the water had some bases in it.

I associate it with the tops of stones in limestone streams, but I don't think it needs to be continually wet. It is the only liverwort (that looks like this) that you find in very base rich water. <"Pellia epiphylla"> can look almost identical, and is also really common, but it grows in less base rich conditions.

AquaMoos sell <"P. epiphylla">.

I'm pretty sure that one is <"Conocephalum conicum">, it looks quite big and chunky, and you can see the very obvious pale dots (air pores), it is a common Liverwort in any damp, bare places.
