A Survey of Wood Decay Fungi
In this article there are many different types of Wood Decay
Fungi that can grow on your living trees. These types are:
White pocket rot, red ring rot (Phellinus pini)
This type in most commone worldwide. It grows on living dead
branch stubs. This fungus can grow up to 10 inches across. They
grow on the heartwood of trees. These have a variety of colors,
size, and shape. They can have irregular tublular pores that show a
maze-like pattern. This infection can have predisposed trees to be
known to have breakage and wind throw.
This type is grown in sapwood of dead and/or dying trees. You
are most likely to see this to trees that have been sunburned or
have had been in a fire. With this happening it can spread to the
living sapwood on any tree. The process of this fungus is moving
outward to inward, which causes the tree to decay.
False turkey tails (Stereum hirsutum)
This type is grown on sapwood of dead and dying trees, branches,
and stumps, which causing white rot. It can also be seen in trees
that have broken branches are that have recently been pruned. They
occur on many oaks and other hardwoods. They typically look thin
and bracketlike and sometimes flattened. They are about 2 inches
across but are often seen smaller.
Turkey Tails (Trametes vesicolor)
This type is grown on many hardwoods and is very common to the
saprot fungus. It can grow on dead trees or branches and seems to
happen on most streesed trees of injured of dying bark. This fungus
can invade to living bark and sapwood. Its a smaller type of fungus
only reached about 4 inches across.
Oyster mushroom (Pleurotus ostreatus)
This type of fungus are large and have been seen up to 6 inches
across. They look mushroomlike, and typically are seen grown on
large branches and trunks. This can be seen on dying trees or
branches that have been through a fire, sunburn or even
mechanically injured trees. This is seen on most oaks and other
Split gill fung (Schizophyllum commune)
This type is grown on many hardwoods. It is known to look small
with a leathery texture. These can grown up to 2 inches across.
They occur on trees that are dying or have injured tisses. Once the
tree has this fungus it can kill adjourning bark, which can also
cause white rot. They occur commonly on trees that have been
through heat, drought or major wounds.
Jack-o'-latern fungs (Omphalotus olivascens)
This type can be found on both dead and living trees that can
grown in clusters. This are known to grow 10 inches long normally
on the soil line of trees or on shallow roots. These are normally
found on oaks and Eucalyptus spp trees.
This type of fungus are solitary or are seen as cluster. They
are typically found on dead and dying trees that have been through
an extensive white rot of sapwood. This can cause major branch or
trunk failure. This type of fungus is known on many oaks as sudden
oak death, but can be seen on many hard woods.
It is very important to check trees for fungus, espcailly if the
tree is still a living tree. It can cause a living healthy tree to
become hazardous which, can fail at any time.
