Slide 1 Fungal Biology

Kingdom Fungi: The Hidden Forest Web

The Vast Underground Mycelial Network

Mushrooms are neither plants nor animals—they belong to their own evolutionary kingdom: Kingdom Fungi!

The mushroom you see on the forest floor is just the temporary "apple" on a vast underground tree. Beneath the moss lies the mycelium: miles of microscopic branching threads (hyphae) that weave through every cubic inch of forest soil.

🕸️
Ecosystem Web: A single cubic centimeter of forest soil can contain over a mile of fungal mycelium.
🌲
Wood Wide Web: Mycorrhizal fungi share sugars, minerals, and defense warnings between trees.

Slide 2 Ecological Roles

Ecological Roles: Decomposers vs Mycorrhizae

Recyclers and Forest Root Partners

Fungi fulfill two primary ecological roles in Tyonek forests:

1. Saprophytic Decomposers: Digesting tough lignin and cellulose from fallen dead birch and spruce logs, recycling carbon into humus.

2. Mycorrhizal Partners: Forming mutualistic partnerships with live birch and spruce roots. The fungus trades mineral phosphorus and water in exchange for plant sugars from photosynthesis.

Slide 3 Anatomical Structure

Mushroom Anatomy: Spore-Bearing Architecture

Cap, Gills, Pores, Stipe, and Annulus

Cap (Pileus): Protective umbrella shielding microscopic spores from heavy rain.

Gills (Lamellae) or Pores: Paper-thin vertical blades or sponge-like tubes that maximize surface area for releasing billions of spores.

Stipe (Stem): Elevates the cap above moss into air currents.

Annulus (Ring) & Volva (Cup): Remnants of the protective veil found on deadly Amanita species.

Why do mushrooms have gills or vertical pore tubes on the underside of their caps?

Slide 4 Laboratory Protocol

Laboratory Protocol: The Spore Print Investigation

Capturing the Microscopic Fingerprint of Fungi

Step 1: Slice the stem off a fresh mature mushroom cap right at the base of the gills.

Step 2: Place the cap gill-side down onto a sheet of paper that is half black and half white (to reveal white vs dark spores).

Step 3: Cover with a glass bowl to block air drafts and let sit for 12–24 hours.

Step 4: Lift the cap to reveal an exquisite, radial microscopic powder portrait of spore drop lines!

Slide 5 Safety & Toxicology

Edible vs Deadly Toxic Fungi in Southcentral Alaska

Universal Safety Rule: When in Doubt, Throw it Out!

Never consume any wild mushroom unless verified by an experienced mycologist! Alaska forests contain delicious edibles (King Boletes, Chanterelles, Hedgehog mushrooms) alongside lethal toxins (Destroying Angel, Amanita muscaria).

Many toxic species contain amatoxins that cause irreversible liver failure within 48 hours with zero antidote. Always photograph, study, and respect mushrooms with clean field ethics.

Slide 6 Cultural Traditions

Dena’ina Traditional Uses of Fungi

Tinder Conks & Traditional Medicines

Tebughna elders have utilized bracket fungi for centuries: Phellinus igniarius (true tinder fungus) was gathered from birch trunks, dried, burned into clean white ash, and blended with tobacco for ceremonial use.

Dense woody conks were also used as slow-burning ember carriers, allowing hunters to transport living fire across Cook Inlet waterways.

Essential Inquiries & Learning Targets

Core Essential Questions:

What is the difference between the visible mushroom fruit body and the underground mycelial network?
How do mycorrhizal fungi partner with birch and spruce tree roots in Western Cook Inlet boreal forests?
How do fungal decomposers recycle dead organic matter into fertile soil, and how do you make a botanical spore print?

Student Learning Objectives:

Identify fungal anatomy: cap (pileus), gills (lamellae), stem (stipe), ring (annulus), and mycelium.
Create a botanical spore print to observe microscopic reproductive spore color patterns.
Classify saprophytic decomposers versus symbiotic mycorrhizal forest fungi.

Curriculum Standards & Activity Protocol

📚 Standards Alignment (NGSS & Alaska Cultural Standards)

5-LS2-1

Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.

NGSS

MS-LS2-3

Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

Culturally-knowledgeable students understand the ecology and geography of the bioregion they inhabit.

Cultural

🏔️ Local Alaskan & Tebughna Context

Tyonek boreal forests are carpeted with mycorrhizal fungi that exchange nitrogen and phosphorus for sugars produced by birch and spruce needles.
Birch polypore and chaga (Inonotus obliquus) have been utilized traditionally across Dena’ina territory for tinder, medicine, and smudging.
Always emphasize strict foraging ethics: never consume wild mushrooms without expert mycological identification.

📦 Required Materials & Classroom Setup

✓ Fresh mature gilled mushrooms (store-bought Portobello or button mushrooms for classroom safety)✓ Index cards cut in half (one white, one black taped together)✓ Clear glass bowls or plastic cups (to cover caps)✓ Sharp paring knife (adult use to remove stems)✓ Water droplets and hairspray (to fix finished spore prints)

🔬 Step-by-Step Hands-on Activity Guide

Step 1: Remove the Stipe (Stem)
Carefully cut or twist off the stem flush with the bottom of the mushroom cap so the gills can rest flat against paper.

💡 Instructor Tip: Do not damage the radiating gill gills.
Step 2: Position on Split Paper
Place the cap gills-down directly over the boundary line between the white and black index cards. Cover with a glass bowl to prevent drafts.

💡 Instructor Tip: The two-color paper guarantees spores are visible whether they are pure white or dark brown.
Step 3: Overnight Spore Drop
Place a drop of water on top of the cap and leave undisturbed for 6-12 hours. Billions of microscopic spores will drop onto the paper.

💡 Instructor Tip: Lift the cap straight up to reveal a stunning radiating starburst spore pattern!
