The Fungi and Slime-Moulds of Coombe Wood

This page of Fungi and Slime Moulds has two parts. The first, comprising the two tables below, is the result of two surveys done by Mary Smith of the Essex Field Club. The first was on September 19th and October 15th 2012. Mary was accompanied by Gwyn Jordan for the first survey, and by John Rostron for the second. They took the photos that accompany the entries. Essex Field Club members also did a survey in the autumn of 2013. Their results comprise the second table.

The remainder of the page is an ad hoc list of species almost all of which were recorded (and photographed if possible) by John Rostron. The identification of these should be taken as, perhaps, less reliable than those in the table above, which have largely been vetted by Mary Smith. Any reference to “me” in the tables refers to Mary.

For many of the fungi listed below, at the left-hand side, there is a small i-symbol [If you hover over this with the mouse, then an information panel about that species will appear, usually with an image. i] before or after the name. If you hover over this with the mouse, then an information panel about that species will appear, usually with an image. Note, however, that a plain i-symbol [i] is purely a space-filler in lists and does not (yet) provide a link.



The Birch Bracket fungus is common and widespread throughout the wood.

Fungi Recorded by the Essex Field Club Surveys

I have grouped these species into five sections. First are the ordinary ‘toadstools and mushrooms’ (or Agarics), with a roughly circular cap and a stipe (stem) below. Then there are the brackets, typically growing out of trees, with an asymmetrical cap and the stipe on one side or no stipe at all. The third group are the earthballs and puffballs. The fourth group are the ‘resupinates’ – a fancy name for those that are flattened against a tree trunk or other surface. This section also includes some small growth forms without an obvious cap and stipe. The fifth and final group are the Slime Moulds or Myxomycetes, which are neither Fungi, Plants nor Animals, but from a quite distinct Kingdom of organisms. They spend most of their lives underground or in rotten wood and then, in moist conditions, they gather together and emerge to form slimy aggregations as their reproductive bodies.

The final column, headed VG, refers to which part of the wood in which that species was found. VG1 is the Village Green area designated in 2007 (south and east of the stream), and VG2 that part designated in 2013 (north and west of the stream).
