Interpret fungus life cycles, fungal biology/ecology
and the impacts of environmental factors

Peridermium quercuum

     
Assess and explain aspects of fungi as they may be related to issues encountered by manufacturers,  attorneys, builders, government agencies, retailers, homeowners and other public or private entities:

 

   
How fungi cause different types of decay: Example 3  Example 4
Formation and impact of mycorrhizal relationships: Example 1  Example 9

Volvariella bombycina

Impact and role of alternate hosts in rust fungi: Example 5
Spore discharge and distribution of fungi: Example 6
Nutritional and environmental impacts on mildew: Example 2
 

 

   
         
  Inform and advise non-mycologically-trained professionals 
 
   Provide information for use in litigation and depositions
         
   

Amanita muscaria

Example 1:  Provide information on mushroom toxicity for poison control centers and health professionals.

Amanita muscaria 
(a mycorrhizal species)

         
      Aureobasidium pullulans Example 2:  Advise attorneys or homeowners on the biology and environmental factors affecting the growth of mildews on wood surfaces and finishes.

Aureobasidium pullulans
       
   

Tree on house

Example 3:  Provide advice to attorneys or homeowners on biological aspects of decay that may cause tree failure.

Brown root-rot resulted in tree failure
         
      Wound on park tree Example 4:  Evaluate and make recommendations regarding park or yard trees attacked by decay fungi.

  Assist homeowners with tree disease problems
             
  Telial horns

Example 5:  Juniper tree infected with cedar apple rust. Innocuous disease caused by spores from apple trees in neighborhood.

Gymnosporangium juniperi-virginianae
  Dutch elm disease
 
 
 

Example 6:  American elm infected by
Ophiostoma ulmi
, probably resulting from spores
carried by a bark beetle. Flagging indicates
that the tree will probably die within 2 years.

   Interpret fungal interactions with trees and other plants
             
Interpret and explain the significance of mycological phenomena such as fairy rings, slime mold appearance, plant diseases and mycorrhizal associations.
          
Agaricus fairy ring  

Black knot of cherry

 

Thelephora terrestris

  Fuligo septica
Example 7 Example 8 Example 9 Example 10
Agaricus bitorquis causes a fairy ring by growing out in all directions from the original inoculum in the grass. The grass will recover and turn green. Black knot of cherry
caused by
Apiosporina morbosa.
It is unsightly
but largely innocuous
Mycorrhizal association between pine seedling and Thelephora terestris -- 
 necessary association for vigorous growth
of trees.
Fuligo septica (a slime mold sometimes called The Blob) is frequently found in wood chip mulch. It lives on bacteria and other surface contaminants and is not dangerous to humans.
