Postia livens (Postia caesia) Miettinen & Vlasák 2018 

Postia caesia is a European polypore. DNA analysis has revealed that we have several different species previously under the name Postia caesiaPostia livens is the most common one found in the eastern and central regions of N.A. Its common name is “Blue Cheese Polypore”.  Postia livens is saprotrophic on both conifers and hardwoods, although the majority that I have come across over the course of nearly 16 years have been growing from dead conifer wood. This soft and spongy polypore with a pubescent or  hairy white cap with blue and gray causes brown rot. Cellulose in the wood is broken down by enzymes produced by the mycelium, but the lignin component is uneffected. Pores are white and like the cap, bruise blue. Fruits from late summer to late autumn. White to pale blue spores. Fragrant. Despite its common name, it is not edible. It used to be in the is the Fomitopsidaceae family of the Polyporales. it is now in the Dacryobolacea family.
