A printable chart to make a spore print and start identification. The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. [1]
Melzer's reagent can be used to test whether spores are amyloid, nonamyloid, or dextrinoid. Spores that stain bluish-gray to bluish-black are amyloid; Spores that stain brown to reddish-brown are dextrinoid; This test is normally performed on white spored mushrooms. If the spores are not light colored, a change will not be readily apparent.
Many types of cystidia exist, and assessing their presence, shape, and size is often used to verify the identification of a mushroom. [13] The most important microscopic feature for identification of mushrooms is the spores. Their color, shape, size, attachment, ornamentation, and reaction to chemical tests often can be the crux of an ...
The dusty texture of many molds is caused by profuse production of asexual spores formed by differentiation at the ends of hyphae. The mode of formation and shape of these spores is traditionally used to classify molds. [4] Many of these spores are colored, making the fungus much more obvious to the human eye at this stage in its life-cycle.
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. [1] Spores form part of the life cycles of many plants , algae , fungi and protozoa . [ 2 ]

Conidia and colony characteristics of the culture led to identification of N. sphaerica as the fungal pathogen. It was hypothesized that this special case of fungal corneal ulcer was caused by transfer of spores to the patients eye from contamination with soil (a common habitat of the fungus) or other matter from the cow’s tail.

The spores are airborne and found in the soil and water, as well as indoors and on objects. The club-shaped spores are single or form long chains. They can grow thick colonies which are usually green, black, or gray. [2] At least 20% of agricultural spoilage is caused by Alternaria species, with the most severe losses reaching 80% of yield. [2]
