Colonial morphology of various specimens of Pseudomonas aeruginosa, including mucoid types. In microbiology, colonial morphology refers to the visual appearance of bacterial or fungal colonies on an agar plate. Examining colonial morphology is the first step in the identification of an unknown microbe.
The English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').

The fungus was originally classified as a subspecies of A. flavus called Aspergillus flavus subsp. parasiticus (Speare) due to its strong resemblance to A. flavus. Indeed, this fungus is very closely related to A. flavus [3] and is often misidentified as the latter. [3] However, the two species are separable based on morphological features. [3]
In March 2010, Aspergillus covered 837 species of fungi. [5] Notable species placed in Aspergillus include: Aspergillus flavus is a notable plant pathogen impacting crop yields and a common cause of aspergillosis. Aspergillus fumigatus is the most common cause of aspergillosis in individuals with an immunodeficiency.
Microscopic morphology of the micro- and macroconidia is the most reliable identification character, but both good slide preparation and stimulation of sporulation in some strains are needed. While small microconidia may not always form, the larger macroconidia aids in identification of the fungal species. [8]
The classical AM fungal identification method of spore extraction from soil and further spore morphological analysis [90] is fraught with complicating issues due to the various strategies and forms of AM fungi, e.g., lack of sporulation in certain species, seasonality, high unculturability, possible misidentification (human error), and new ...
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.
