Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

Supplied as tube cultures. Comes with culture and handling instructions, as well as the manual Working with Fungi.

Eight strains: a1 (HAO), α1 (HBO), a2 (HAR), α2 (HBR), a3 (HAT), α3 (HBT), a4 (HART), α4 (HBRT).

Aeolosoma sp. A small, freshwater Oligochaete, Aeolosoma is characterized by colorful oil droplets in its body. It’s easy to culture large quantities of this microscopic organism for use in regeneration experiments: Simply add hay and wheat grains to hay medium. Culture instructions are included. Size: 2–3 mm.

Conifers come in all shapes and sizes — and so do their cones.
Includes: 6 pine cones, 6 spruce cones and 6 cedar cones.
*Pine cone factoid: Pine cones can forecast the weather! In dry weather, the scales dry up and open out. If they start to close up, wet weather is coming!

Mature Drosophila are cultured in our own labs, and are marked with the culture initiation date. Culture is shipped in our instant medium in a shatterproof vial. The Fruit Fly pupae will usually appear within ten days of the ship date. You will also receive WARD’S Drosophila Culture Guide. Note: We can supply any of our single strains in the larger quantity for 100 students. Call our Customer Service department for details.
