Diversity and ecology of truffle fungi in the Rocky Mountains
Speaker: Jack States

Dr. Jack States has this to say about his July presentation for CMS:

My research in collaboration with wildlife resource managers has shown that the ecological importance of hypogeous (truffle) fungi goes well beyond their beneficial symbiotic relationship with forest tree root systems (as mycorrhizae) and nutrient cycling.  Truffle fungi are an important, and in some cases essential, food source for many forest animals, including arboreal and ground Jack Statesdwelling squirrels, small rodents, deer and elk,  and even insects. Comprised of many genera and species, truffle communities perform interconnecting, and in some cases interdependent roles in food webs of Rocky mountain conifer forests, wherein the fungi develop symbiotic root associations with trees thus providing nutrients to the host and receiving in return photosynthates (sugars) to fuel their growth. Forest adapted animals, particularly tree squirrels, consume the truffle fruiting bodies as major parts of their diets and disperse the fungal spores throughout the forest. Healthy squirrel populations provide an essential prey base for forest carnivores, especially northern goshawks and northern spotted owls, and these birds are thus intimately connected to the fungi through both the prey base and the  trees (supported by the mycorrhizae) for nesting habitat.  So tightly linked are these food web components in Rocky Mountain ponderosa pine forests that forest managers have selected tassel-eared squirrels, Sciurus aberti, to be the official indicator of forest health and ecosystem sustainability. The steps leading to the discovery of this remarkable relationship and its current application in forest management policy and guidelines will be presented.


New Meeting Location for CMS in 2009

The Colorado Mycological Society has a new meeting location for 2009! At the end of the 2008 season the Denver Botanic Gardens notified CMS, and other plant societies, that we would not be able to meet there in 2009 because of the extensive construction work being carried out at the Gardens. CMS therefore appointed a committee to come up with a new meeting location.

In 2009 the Colorado Mycological Society will be meeting in the Asbury Event Center at 3011 Vallejo Street in historic North Denver (map). The Asbury Event Center is in the old Asbury Methodist Church (built in 1890) complex which is today privately owned and no longer functioning as a church.

We are quite excited about the new meeting location. The main meeting room is large and will comfortably accommodate our members. There are also adjoining rooms where we can hold Board meetings and conduct classes. And a very big plus for us: CMS will have use of a kitchen adjoining the main meeting room. There is also off street parking in a lot across the street from the Center.

Directions: To reach the Asbury Event Center from east of I-25 take Speer Blvd. north. After crossing I-25 turn right on Zuni Street. Proceed north to 30th Street. Turn right and go two blocks to Vallejo Street. Asbury Event center is on the northwest corner of 30th and Vallejo.

From I-25 take the Speer Blvd (north) exit and proceed to Zuni Street. Turn right on Zuni Street. Proceed north to 30th Street. Turn right and go two blocks to Vallejo Street. Asbury Event center is on the northwest corner of 30th and Vallejo.

Entrance: There are several entrances into the facilities. The door to our meeting room is at the northeast corner of the building.

We look forward to seeing you in our new location of the Colorado Mycological Society.



CMS Meetings:

  • Until further notice CMS will not meet at the Denver Botanic Gardens (posted Jan. 2009) — Meetings are held on the second Monday night of each month, from March Coprinus atramentariusthrough October, at 7:30 PM at the Denver Botanic Gardens, 1005 York street (map). The meetings are in Mitchell Hall. There is no charge to get into the Botanic Gardens to attend a CMS meeting.

  • CMS meetings provide an informal opportunity to socialize and exchange information with others interested in mycology.

  • Each meeting features a lecture and/or slide presentation on Yellow feetmycology or a related subject.

  • Speakers include nationally known mycologists, outside specialists and knowledgeable members

  • Visitors & members are encouraged to bring the mushrooms they find to the meetings.

  • Knowledgeable members will be happy to help you identify the mushrooms you have found.
