NS3977 : A slime mould - Physarum leucophaeum

taken 8 years ago, near to Renton, West Dunbartonshire, Great Britain

A slime mould - Physarum leucophaeum
A slime mould - Physarum leucophaeum
Near a large man-made mound (NS3977 : Mound beside the River Leven), a single log was host to at least five different species of slime mould at the same time.

[These were: LinkExternal link (Arcyria denudata), LinkExternal link (Ceratiomyxa fruticulosa), LinkExternal link (Metatrichia floriformis), Physarum leucophaeum, and LinkExternal link (a Trichia species). All but the second of those links show the species on this log.]

The spore-producing bodies (sporocarps) shown here were partly concealed beneath a piece of peeling bark. The rounded top part is less than a millimetre across; through a lens, it is seen to be densely frosted with lime granules (in this context, "lime" refers to various calcium salts). The deeply-furrowed stalks are also lime-covered.

Some of the sporocarps show a brown interior, consisting of spores and of a network of colourless threads. This network has little pieces of lime at some of the nodes. (As is often the case, a microscopic examination was needed in order to identify the species; simply comparing a photograph of its macroscopic appearance with that of other species does not allow for accurate identification.)

This is a very common species; according to "A Census Catalogue of the Myxomycetes of Great Britain and Ireland" (Bruce Ing, 2000) it has been recorded in all but one of the 112 botanical vice-counties of Britain, and from most of those in Ireland.
