It took some digging throughout the
blast hits. All of the hits were shelf
fungus hits. A quarter of the way down
was Tyromyces hit which began to lead
me in the right direction. When doing PCR
on this fungus it was all white and then turned brown with age. This matches the description of leucospongia. I was reassured of making the conclusion that
this was leucospongia once I stumbled
across it because it jogged a memory from when I went on the mushroom foray (a
few weeks later). One of the experts had
pointed out an identical, all white shelf fungus and called it marshmallow
fungus.

#12 and 15 Need much better close ups- use at least dissecting scope with camera to see pores in polypore and to verify absence of soredia in lichen. Also taking fresh pictures and getting the spore prints would have really helped. Luckily you had DNA data to help guide you to the marshmallow polypore...nice work with that one. When following the keys, please reference the description when you say 'not as above'..say what exactly it isn't.
ReplyDeleteOverall a nice collection, but the pictures are hindering visualization of important characteristics. Your logic with the keying guides seems appropriate, but difficult to verify with old samples and lack of proper magnification.
