Fossombronia wondraczekii Acid Frillwort

Similar to Fossombronia pusilla and growing in similar places (see description of that species). It is best distinguished from it by microscopic examination of the spores whose surface appears to have 35-40 spines in side view (see photo). It also has a similar distribution in Britain and in West Glamorgan. Sporophyte capsules are common on this thallose, monoicous liverwort.
