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]
This reference describes morphological characters of AMF genera, and descriptions of then-known species, which is still useful as identification of AMF species via DNA sequencing presents difficulty as each spore can yield many Operational Taxonomic Units (OTUs). [23]
Examining colonial morphology is the first step in the identification of an unknown microbe. The systematic assessment of the colonies' appearance, focusing on aspects like size, shape, colour, opacity, and consistency, provides clues to the identity of the organism, allowing microbiologists to select appropriate tests to provide a definitive ...
The spore wall is made up of three layers all with distinct phenotypes. The first layer is hyaline and mucilogenous and is approximately 1.4–2.5 μm thick (mean = 2.1 μm). This layer is found in the juvenile spores of F. mosseae, and degrades as the spore matures and goes through sloughing, producing a granular appearance.
Gigaspora margarita is distinguished primarily by the morphology of its spores. Young spores are often salmon colored and will become pearly white to yellow-brown at maturity. A mature spore has three cell wall layers (L1, L2, L3): L1 is the outermost layer which forms the rigid and smooth shell of the spore.
Normally, spores in fungi are discharged into still air, but in A. terreus, it resolves this problem with a long stalk and it allows the spores to discharge into air currents like wind. [18] In turn, A. terreus has a better chance to disperse its spores amongst a vast geography which subsequently explains for the worldwide prevalence of the fungus.
Microsporidia produce highly resistant spores, capable of surviving outside their host for up to several years. Spore morphology is useful in distinguishing between different species. Spores of most species are oval or pyriform, but rod-shaped or spherical spores are not unusual. A few genera produce spores of unique shape for the genus.
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. It is easiest to see the color change under a microscope, but it is possible to see it with the naked eye with a good spore print.
