Introduction

• Aim
• raise students' interest in local fungi by making
  a homepage introducing the local fungi.

5

• Fungi provide a critical part of nature's
  continuous rebirth
• fungi recycle dead organic matter into useful
  nutrients.
• Some parasitic
• Many plants are dependent on the help of a fungus
  to get their own nutrients, living in a symbiotic
  relationship.

6

• Homepage to show different species of local fungi
• 2 outings for studying and sampling of local
  specimens of fungi
• Identification of samples and photos taken

7
Outings to Tai Po Kau Nature Reserve

• We made 2 outings to Tai Po Kau Nature Reserve to
  collect samples for local specimens of fungi

8
First outing

• Date 14 July, 2002
• Time 230 pm 430 pm
• Objectives
• To learn to identify different species of fungi
• To observe the habitat of different species of
  fungi and their inter-relationship with other
  species.

9
Second outing

• Date 21 July, 2002
• Time 1000am 1230 noon
• Objectives
• To collect samples of fungi species, about 50-60
  specimens.
• To take photos for identification
• To mark the types of substratum where each
  species of fungi grow on.

More species and population of fungi were found
this time. WHY?
10
1st outing
2nd outing

• Reasons
• Humidity
• Higher in the 2nd trip
• Rained before
• Moisten the substrata for growth of fungi
• UV index (amount of sunlight)
• Lower in the 2nd trip
• held in the morning less sunny.
• Prevent desiccation due to water evaporation.

11
Identification

• Identified by observing the appearance of
• Pileus
• Size, shape, colour
• Lamellae
• Arrangement of gills
• Stipe
• Thickness, length, colour
• Habitat
• (substrata)

12
Identification

• By comparing the above properties of the specimen
  and that described in reference book
• Examples Bookmarks
• Reference books
• ??????
• ????
• Hong Kong Fungi

13
Identification

• Sort the different species of fungi by the types
  of substratum where they grow.
• Leaves
• Soil
• Trees / stems

14
Types of Substratum

• Leaves
• Dead leaves on the ground
• Cellulose digested
• Fungi
• All soft and vulnerable
• Small in size
• Thin pilei, slender stipe
• Dried and collapsed after taken from habitat for
  several hours

15
Types of substratum

• Soil
• Damp
• Digested and dissolved materials absorbed
• Fungi
• stronger
• Generally larger in size
• Thicker pilei and stipe,
• some no stipe
• Can maintain shape after several hours

16
Types of substratum

• Trees / stems
• Softened
• Can be pressed in easily
• Lignin, cellulose digested
• Fungi
• Stronger and harder
• Growing in clusters
• Some have permanent bodies

Making of the homepage

• http//www.geocities.com/popfungi/
• Map of Tai Po Kau Nature Reserve
• Life cycle of fungi
• Identified species in 3 categories
• Galleries
