Mushroom



The fruiting body (mushroom) just opened





The fruiting body half opened






The fruiting body is fully opened










Why do the mycologists (expert of fungi) call mushroom fruiting bodies? This is because the mushroom (called basidiocarp) is the sexual reproductive structure of a fungal group called the Basidiomycetes. On the underside of the umbrella-like structure are found 'ridges' which radiate from the centre. On these ridges (called gills) are found the 'fruits' of the mushroom (called basidium, plural=basidia).

On this basidium are found 2, 4 or 8 seed-like structures called the basidiospores. The relation between basidium and the basidiospores is somewhat equivalent to the cashew nut fruit, which bears the seed on the outside of the fleshy fruit.

The characteristics of these structures, namely basidiocarp, basidium and the basidiospores are used to classify the various mushrooms into the different taxa as shown below.

Classification of Basidiomycetes

There are books that we can refer to, but the easiest to get is the Internet

Kingdom: Fungi
Subkingdom: Dikarya
Phylum: Basidiomycota
Subphylum: Agaricomycotina
Class: Agaricomycetes
Subclass: Agaricomycetidae
Order: Agaricales
Family (33): Agaricaceae
Genus (85 genera) Agaricus??
Species (1340 species) ????

Never, never, never try to eat mushroom collected from the field, unless you are an expert. Buy the ones sold in the supermarket.

Dr. Mawar,

Memang cndawan kukur ni sedap kalau masak sup. Cendawankukur atau cendawan sisik ini tumbuh pada kayu-kayu yang sedang mereput. Belainan dengan Agaricus spp, kulat ini lebih liat (keras).

Nama saintifik kulat kukur ialah Schizophyllum commune. Dari segi pengkelasan cendawan ini sama Order dengan Agaricus spp tetapi berada dalam Famili yang berlainan, iaitu Famili Schizophyllaceae.

Kulat ini dikaitkan dengan aktiviti antikanser (http://projekcendawan.blogspot.com0. Bagaimanapun kegunaan saintifik bahan aktif dalam cendawan ini sudah di patenkan. Kita semua selalu terlambat. Cendawan kita punya, faedah dapat kepada orang lain.
