can you mention one of its microscopic feature?
The spore shape
Phellinus ellipsoideus
 The spore shape is one of the features that makes the species readily recognisable microscopically, and the spores measure from 4.5 to 6.1 by 3.5 to 5 micrometres (μm). 
what kind of species is phellinus ellipsoideus? Polypore fungus in the family Hymenochaetaceae mention any one delimitations of the first term?

Phellinus ellipsoideus [SEP] Microscopic features
Most of the tissue of a fungal fruit body is made up of hyphae, which can be of three forms: generative, skeletal and binding. In "P. ellipsoideus", the tissue is dominated by skeletal hyphae, but also has generative hyphae; it lacks binding hyphae. For this reason, the hyphal structure of "P. ellipsoideus" is referred to as "dimitic". The hyphae are divided into separate cells by septae, and lack clamp connections. The skeletal hyphae do not react with Melzer's reagent or Lugol's solution, and are not cyanophilous. While the hyphae will darken when a solution of potassium hydroxide is applied (the KOH test), they remain otherwise unchanged.
