Without having to look at the colony, the hyphae, or macroconidia-one can identify the dermatophyte by a simple color test.
12.
Once the Koa tree dies, the fungus invades all tissues and, upon reaching the dead plant surface, sporulates profusely producing macroconidia and chlamydospores.
13.
If soil conditions are moist, roots are also likely to show blue masses of spores ( macroconidia ) around the taproot just below the soil surface.
14.
These are different-appearing macroconidia in the two common species of " Microspora ", and typical microconidia in " Trichophyton " infections.
15.
The identification of rough-walled macroconidia, a hallmark of the Microsporum genus, lead to the dermatophyte being classified as " M . gallinae ".
16.
Direct examination with KOH of skin, reveal mycelium and masses of arthroconidia in some chains; KOH examination of hair produces distinctive large macroconidia in chain or irregular masses of hair.
17.
The soil-borne " F . oxysporum " reproduces only asexually . " F . oxysporum " produces three types of asexual spores : microconidia, macroconidia, and chlamydospores.
18.
For example, the basal cells of macroconidia in some " Fusarium " species have hooks or notches whilst others do not, but these differences are not always sufficient to distinguish closely related fusaria from one another.
19.
A microscopic examination shows a marked distinction : " H . capsulatum " produces two types of conidia, globose macroconidia, 8 15 �m, with distinctive tuberculate or finger-like cell wall ornamentation, and ovoid microconidia, 2 4 �m, which appear smooth or finely roughened.
