Pored or somewhat maze-like on underside [bracket polypores]



In most species of this sub-group, the underside of the fruitbody has pores. In most cases the pores are small (two or more per millimetre) and of uniform size and appearance. However, in some species the pores are larger or of irregular shapes and sizes or incomplete and so giving a maze-like appearance. Sometimes you may see a mix of pored and maze-like regions in the one fruitbody.

 

In the following hints you see examples of useful identification features and a few of the more commonly seen genera in which at least some species (not necessarily all) show those features.

 

Hints

Red, fleshy texture: Fistulina.

Orange, leathery to corky texture: Piptoporus, Pycnoporus, Rigidoporus.

Pinkish to pinkish-brown, texture of firm rubber: Rhodofomitopsis.

Corky texture; creamy to yellow- brown: Perenniporia.

Upper surface furry & orange-brown to red-brown, pores white: Postia.

Large, creamy to pale brown, on live trees: Laetiporus.

 

On the wood of native or introduced conifers: Gloeophyllum.

 

Pores large, several millimetres in diameter: Hexagonia.

Underside maze-like or a mixture of pores & irregular gills: Cerrena, Gloeophyllum.

 

Hard & woody, black upper surface, pores brown to bronze: Phellinus.

Hard & woody, brown upper surface, pores white & marking brown: Ganoderma.

Hard & woody, brown upper surface, pores white & not marking brown: Fomes.

 

Roughly semi-circular, leathery, concentrically banded upper surface; white pores: Trametes.

     Note: Trametes is a very common genus and is the one (with these features)

                 that you are most likely to see.

Very possibly a Tubifera sp forming but there is not enough detail to be certain - the description of 'a red blobby thing' certainly describes the early stage but this image does not show the individual bodies beneath the peridium. With this species its important to see it at this stage and again in 24hrs when it has become brown at maturity - at the mature stage it is generally overlooked as it blends into the substrate so completely.
Tubifera is a complex genus with several species which are differentiated by the formation of each individual at its tip, some of which are quite pointed while others are ovate and flattened, and its spores which are variable is size.

A slime mould - perhaps a Tubifera...but that's based on a hazy recollection!
