Identification notes
You are most likely to confuse this species with Conocephalum conicum; the 2 species were was only separated relatively recently in 2004. The paper introducing C. salebrosum is available in the resources section below, along with a link to a page comparing the 2 species.
Dull-looking Conocephalums with a clearly reticulate surface growing away from water are good candidates for C. salebrosum but – until you can recognise them by ‘jizz’ – should be taken home for checking. Note however that microscope characters such as thallus border can be quite variable.
