Observation 200041: Trametes conchifer (Schw.: Fr.) Pil.
When: 2015-01-28
No herbarium specimen

Notes: Many specimens fruiting on a decaying log. These specimens represent the mature fruiting body of this fungus. A smaller one, which I collected, measures 3 cm. wide and is a paper-thin 0.5 mm. in thickness. Please see my Observation # 195842 which shows the immature fruiting body. I’ve not been lucky enough (yet)to find both the immature and the mature forms of this fungus in one place at the same time. That fortunate “find” can be seen in the MO observation referenced below.

As Michael Kuo says on pg. 326 of “Mushrooms of the Midwest” (2014) under his comments regarding P. conchifer, “The unusual combination of fruiting body forms is distinctive …” Aurora,in his Key to the Polyporaceae & Allies (#14) on page 55,2 “Mushrooms Demystified” describes this distinctive combination as follows: “Fruiting body usually preceded by a small, often zoned cup-or saucerlike ‘nest’ (0.5-2cm broad) from which small whitish to yellowish shelves (fruiting bodies) develop …” It is a mystery to me — and fascinating — that some fungi can have such different features at their different developmental stages. The only other fungus I have experienced this with — so far — is Kretchmaria deusta.I was lucky enough to find both forms of this mushroom at the same time in one location (my Ob. 196227). As a relative newbie mycophile, I find it much more difficult to recognize and ID a mushroom that goes through such a dramatic developmental metaporphasis when I only see one form at a time. As I mentioned in my Notes for this observation, a super example of both forms of P. conchifer was captured by another MO user in Ob. 110690. Thanks, Danny for taking a look at my observation and taking the time to comment. I am appreciative of all the feedback I get.
