Bracket/Resupinate - 'Incertae sedis' (Crimped gill)

All images on this website have been taken in Leicestershire and Rutland by NatureSpot members. We welcome new contributions - just register and use the Submit Records form to post your photos. Click on any image below to visit the species page. The RED / AMBER / GREEN dots indicate how easy it is to identify the species - see our Identification Difficulty page for more information. A coloured rating followed by an exclamation mark denotes that different ID difficulties apply to either males and females or to the larvae - see the species page for more detail.

Fungi

Fungi are not plants, as was thought to be so in the past, but in a separate Kingdom of their own.  In most cases, the main body of the fungus is hidden from view.  It is a network of threads (hyphae) collectively called a 'mycelium', which permeate the substrate on which the fungus grows.  The hyphae absorb nutrients and water from the substrate.  The reproductive spore-producing structures, such as the familiar mushroom or bracket, are the visible parts of the fungus. 

The Fungus Kingdom is extremely diverse, and includes many microfungi that are rarely recorded.  Most of the larger species are in one of two major divisions or Phylum, based on the way the fungus reproduces.  Basidiomycota (sometimes called 'spore-droppers') include mushrooms and toadstools, brackets, corals, puffballs, jellies, rusts and smuts. The Ascomycota or 'spore-shooters' includes cups, morels, yeasts and many other smaller fungi.  

Taxonomy is very complicated and is liable to change as the true relationships between species are worked out.  In the sections below, we have grouped fungi into categories based on their structure and appearance rather than their place in the scientific taxonomic hierarchy.  There is more information under each section.

Recording fungi

Always note the substrate or host-plant on which the fungus is growing, and the habitat.  To identify many large species, it is helpful to get a good photograph of the cap (from the top), the gills or spore-producing structures (from underneath) and the stipe or stem (from the side) - three images from three angles, rather than images from much the same angle. 

Always note the texture of cap and stipe; the smell; and the presence of any staining or 'milk' produced when the cap, gills, stipe or body of the fungus is bruised. 

The colour of the spores can be very helpful.  It is best seen by taking a spore-print from a collected specimen - advice on doing this is in many of the resources below.  For some fungi, microscopic examination of the spores may be needed for identification.

Resources

The Leicestershire Fungi Study Group is a great place to start if you want to learn about fungi. They welcome new members. Their annual programme of study forays is led by enthusiastic and knowledgeable leaders. There are also indoor microscopy sessions held in Leicester. This is a really excellent way to broaden your knowledge, and make friends who share your interest in fungi.

There are many field guides, but none of them contain all the fungi you will find, or have all the photos or information you need, so it is a good idea to check several different books and websites.

Pat O'Reilly's First Nature website  has some helpful advice and tips on identifying fungi.

The British Mycological Society website is a good source of information, mostly aimed at the expert.

Brackets, Crusts and Resupinates

This section includes many of the fungi that grow on the trunks and branches of trees.  Often the species of tree on which they are growing - including dead wood - is an aid to identification.  Many used to be in the family Coriolaceae, but this has now been split into several families.  

Brackets project from the trunk or branch or log, and often have a woody or leathery feel.  Some are perennial, growing to a large size over many years - these shouldn't be collected.   Spores form in tubes on the underside of the brackets, which end in pores that can be rounded, mazelike, elongated, angular, etc. The shape of the pores can help to identify them, so always photograph the underside.  Crusts, Porecrusts and Resupinates form a layer over the wood substrate.  Some species have growth forms with a resupinate part and bracketing part to the fungus.
