Wow Jenny, lucky you!! You've been able to capture an early developmental stage in this Phlebopus not often seen and very rarely understood. Namely the immature pores, which look pale coloured, instead of the typical yellow which you can see coming on image 2, right side of the left hand specimen. This is because of a covering similar to a partial veil. It was described by Destinger et al (2010) as '..a layer of tangled white hyphae that covers the immature tubes (equivalent to a partial veil) a feature that effectively 'plugs' their pores and has often been referred to, misleadingly as 'stuffed pores'.' Josef Sutara (2014) in an indepth study of this characteristic found that it is a layer of cheilocystidia (special sterile cells on the fertile section of the fungus) covering the pores supported by the growth of hyphae in the flesh (trama) under these cystidia. If you have a handlense have a look at these covered pores. Sutara said the cheilocystidia covering looks like 'hoarfrost'. I have yet to see this first hand.............sigh!
