Classification of Sub-division of Deuteromycotina
i) Budding ( yeast or yeast like) cells with or without pseudomycelium. True mycelium lacking or not well developed.
ii) Mycelium well developed assimilative budding cells absent.
Sub division of Deuteromycotina
Family: Monliaceae ( Hyphae, Conidia and Conidiophores are hyaline or colourless)
Genus: Pyricularia Conidiophores long, slender, simple, rarely branched septate, Pyriform conidia 2 to 3 celled. E.g. P.oryzae- Blast of rice.
Family: Dematiaceae ( Hyphae, Conidia are coloured)
Conidia and conidiophores are coloured.
Muriform type condidia.
E.g. A.solani-Early blight of tomato and potato
Conidia multiseptate, worm like.
e.g. C.arachidicola- Tikka of G.nut.
Conidia 3 to many celled.
E.g. H.oryzae- Brown spot of paddy.
Genus4 : Drechslera
e.g. D.maydis – Blight of Corn
Sub Division of Deuteromycotina
They are formed in soil ad black in colour having size 100µ. E.g. R.solani-root rot of tomato
They are formed as white cottony growth on the infected portion of plant brown in colour having size 100 -300 µ.E.g. S.oryzae- Steam rot of paddy.
i) Order- Melanconiales
Conidiophores are brown hyaline septate branched sickle shaped having rounded ends. E.g. C.falcatum –red rot of sugarcane
Conidia multiseptate, fusiform type, 2 to 5 septa. 3 to 9 apical, simple branched appendages. E.g. P.theae-grey blight on tea.
ii) Order- Sphaeropsidiales
Leaf spot of fungus
E.g. S. thespesiae- septotria leaf spot, S.avenae-leaf spot oat.
