A visit was recently made to Woolmer Forest in North Hampshire v.-c.12 in an attempt to refind Protolophozia herzogiana. This was not successful, but the locality provided a rich assemblage of leafy liverworts including this Odontoschisma denudatum. This attractive species with bright gemmae on attenuated shoots is found typically on moist peaty banks but appears to be declining. The plants were growing through a mat of algal slime due to atmospheric nitrogen deposition which is a major threat to small leafy liverworts.
