Attheya is a genus of small single celled diatoms. Some of these species were earlier regarded to belong to Chaetoceros, or to , the taxonomic status of some of these species are still debated.[1]
Description[]
They are distinguished morphologically from Chaetoceros by the structure of valve outgrowths or girdle bands. The girdle bands can only be seen with an electron microscope.[2] Resting spores are seldom observed. Vegetative cells tend to attach to different substrates, including other diatoms,[3] and are sometimes referred to as epiphytic. However, they are also observed to be planktonic.
