Riccardia latifrons on Sitka Spruce Log, Afan Forest Park
Apical portion of Riccardia latifrons leaf
Third record for Glamorgan (I think) and second for NPT. Like Barry's earlier record for Crynant Forest this colony was on a Sitka Spruce log. This was in the Argoed Valley, above the Visitors Centre. Elsewhere in the park (Pelenna Valley) we recently had logs with Riccardia chamedryfolia and R. palmata. Common associates on decorticated Sitka logs include Nowellia curvifolia (often abundant), Lophocolea bidentata, L. heterophylla, Campylopus flexuosus, Tetraphis pellucida, Cephalozia bicuspidata, Diplophyllum albicans and Lepidozia reptans.
Riccardia latifrons is probably more widespread in South Wales than we think, even though it may not be very common- there's a lot of Sitka logs out there!
And if your looking at Sitka logs, you'll probably see some nice fungi, particularly Stagshorns e.g. Calocera viscosa and C. pallidospathulata ........ sorry, couldn't resist it.
