Observation 197590: Trametes conchifer (Schw.: Fr.) Pil.

When: 2015-01-22

Collection location: Lower Meramec Park, St. Louis Co., Missouri, USA [Click for map]

Who: weed lady (Sylvia )

No specimen available

Collected a number of these. They were all found on branches which were on the ground. The size ranges from about 2 cm. to 5 cm. Some have a rudimentary stalk. Thin and papery. Pores beneath – maybe becoming tooth-like. Color whitish to grayish. Faintly zonal. Believe this to be the species without the “cup”. These are the caps. Michael Kuo says “when this polypore is found without the immature, cup-like forms present, it can be difficult to identify”. I agree – at least for me. I also have another observation # 182290 which shows both the cup AND the cap which was found in the same park.

If that one has a D under the year, it is valuable as I recall from my coin collecting days.

I have a few that I keep just for the purpose of showing size when I take photos of fungi. My oldest is 1914. I am searching now for an Indian head penny. Think that was the one prior to the wheat ones.

wow a wheat back penny

“whats the point?” The point of his first comment was to explain why he thought P. conchifer was not a reasonable species identification based on his species concept. The point of his second comment was to redefine and educate us on his new species concept of P. conchifer.

“what species?” I don’t understand the question

“all this “speculation” and no proof…” What speculation? Depending on our definition of speculation over 95% (rough guess) of MO observations can be considered speculation.

“barf…” Not sure how this is beneficial to the conversation

P. conchifer is a two-part fungus: one sterile cup which forms at the base, above the point of attachment, one poroid, fertile “shelf,” as seen here, which can be found without than the sterile tissue (or vice versa), hence the easy confusion with Trametes… which this may well still be, depending on your fondness for the genus Poronidulus.

many thanks to Parker V. for the clarification.

Trametopsis cervina and more.

This is an old trametes , Trametes villosa or Trametes hirsuta

my concept

of this sp. is circular, centrally-stipitate pilei. these are all reniform/laterally stipitate.
