Homobasidiomycetidae
The homobasidiomycetidae are divided into two distinct groups;
M.H. Zoberi, 1972. Tropical Macrofungi. Page 13-19
- Hymenomycetes: characterised by basidia which develop in a well defined hymenium which becomes exposed even when the spores are still undeveloped. Examples of Order :1) Aphyllophorales (Family: Thelephoraceae, Clavariaceae, Hydnaceae, Polyporaceae) 2) Agaricales ( Hygrophoraceae, Tricholomataceae, Amaniataceae, Agaricaceae, Coprinaceae, Bolbitaceae, Cortinariaceae, Boletaceae)
- Gasteromycetes: having poorly defined hymenia closed, at least at an early stage of the development of their fruit bodies; basidiospores are not violenlty discharged from their sterigmata. Examples of Order 1) Phallales (Family: Phallaceace, Clathraceae), 2) Nidulariales (Family: Nidulariaceae, Sphaerobolaceae) 3) Lycoperdales (Family: Lycoperdaceae, Geastraceae) 4) Hymenogastrales (Family: Podaxaceae)

Basidiomycetes
Basidiomycetes are divided into two sub-classes;
M.H. Zoberi, 1972. Tropical Macrofungi. Page 12.
- Heterobasidiomycetidae: the basidium is either septate or deeply divided and the basidiospores are capable of germinating by repetition. These include the rusts, the smuts and the jelly fungi. Example: i) Tremellales ii) Tremellaceae iii) Auriculariaceae
- Homobasidiomycetidae: the basidium in neither septate nor deeply divides and the basidio-spores usually germinate by a germ tube. The Fungi included in this sub-class are very common and are generally known as mushrooms, toadstools, puffballs, stinkhorn, bird's-nest fungi and bracket fungi bracket fungi

Media for culture fungi
Media for culture fungi
Water Agar (WA)--use for isolating fungi from surface-sterilized substrates.
Antibiotic Agar (AA)--use for isolating fungi from substrates not readily surface-sterilized, or to clean up a culture contaminated with bacteria.
Acidified Cornmeal Agar (ACMA)--use for isolating fungi from substrates that are likely to be contaminated with bacteria. Not a substitute for AA, but the acidity inhibits bacteria and the medium supports the growth of a wide range of fungi.
Cornmeal Agar (CMA)--use for growing a wide range of fungi, particularly members of the Fungi imperfecti; provides a good balance of mycelial growth and sporulation.
Potato Carrot Agar (PCA)--considered a relatively weak medium somewhat comparable to CMA, good for some Fungi imperfecti.
Malt Agar (MA)--lacks peptone, and is useful for culturing many Ascomycota; sporulation in some species is inhibited by peptone.
Malt Extract Agar (MEA)--a good growth medium for soil fungi, fungi isolated from wood, basidiomycetes, etc. An all-purpose type of medium.
Potato Dextrose Agar (PDA)--a relatively rich medium for growing a wide range of fungi.
Potato Dextrose-Yeast Extract Agar (PDYA)---good for growing cultures derived from mushrooms.

Ganoderma australe, belonging to the group of Ganoderma species without a shiny, laccate crust;sometimes parasitic on trees.
Ganoderma tropicum
Ganoderma tropicum
Ganoderma tropicum , one of the many species of bracket fungi with a highly polished, waxy crust.
Microporus affinis
Microporus affinis
Microporus affinis, commonly found on dead wood, laterally attached with a short, dark stem.
Ganoderma sp.

Microporus sp. - Kelintik Kera
Microporus sp, a very common, thin flesh-but tough polypore; the pores are minute and almost invisible to the naked eye.
Amanita sp. - Destroying Angel
Amanita sp.
Nice to hold, but highly poisonous and deadly when consumed.
Basidiocarp of Amanita sp. with brightly coloured caps often ornamented with scales. Many amanitas are mycorrhizal, growing and forming their basidiocarps in close association with forest trees. The basidiocarp is complete with a ring and volva.
Order: Agaricales
Family: Amanitaceae
Genus: Amanita
Common Name: Death Cap or Destroying Angles.
