Ambispora granatensis is an arbuscular mycorrhizal fungal species in the genus Ambispora, family Ambisporaceae. It forms spores of the acaulosporois and glomoid morphs, thus the Ambispora classification.[1] It was discovered in Granada Spain in 2010 and has unique spore characteristics, which distinguishes the species from the others in its genus.[2]
The genus Ambispora is the only genus of the Ambisporaceae family. Species in this genus are characterized by having the potential for spore dimorphism (glomoid and acaulosporoid).[3]
The Ambisporaceae family is separated from the other families in the Archaeosporales order due to differences in the rDNA characteristics.[4]
Morphology
The species is found to form spores of the acaulosporoid and glomoid morphs, which explains the classification under the genus Ambispora. Like the other species in the genus, this species has two spore types.[5]
A unique characteristic of only this species, differentiating it from the others in its genus, is the spores form three walls rather than the commonly seen four-wall structure.[6] They have a "papillae-like" rough outer cell wall surface that can be difficult to identify within a few hours of development however, when placed in water it becomes more clear.[7] Both spore types tend to be smaller in size, having a diameter of around 90–150 μm.[7] They are the commonly seen color of the acaulosporoid morph, ranging from glassy translucent to white or even pale yellow.[7]
Glomoid spores are formed either in a small cluster of 2-10 or one single spore alone.[7] The acaulosporoid spores form individually in the soil on a short pedicel that is branched off of the neck of a soporiferous saccule.[7] The species spores can be differentiated from the other species of the genus due to its thin outer wall.[7]
