Bishboshjosh Posted December 26, 2014 Report Posted December 26, 2014 My pooch came across this this morning. First thought was the prince but really am just starting out so haven't got a clue.
Dave W Posted December 26, 2014 Report Posted December 26, 2014 First, "100%" is a tall order when it comes to mushroom ID. In fact, over at Mushroom Observer (online) the system used there includes an ID-proposal confidence statistic (percentage) that does not potentially register a 100% confidence level. But I think I can suggest a few good possibilities for your mushroom, Bishboshjosh. Looks like one of the types collectively known as "Shaggy Parasols." The genus for these types used to be Lepiota (older field guides), and some books still list them under the genus Macrolepiota. But I believe the current correct genus is Chlorophyllum. Potential species names include the white-spored Chlorophyllum rhacodes, C. olivieri, and C. brunneum, as well as the green-spored species C. molybdites. C. molybdites (green spored) can cause drastic flu-like symptoms if ingested. The white-spored species are edible (when well-cooked) for some people, but others are sensitive to eating them. A spore print should be taken. C. rhacodes has flesh that often bruises saffron/yellowish when cut damaged. Also, confusion with white-spored Amanitas is possible, especially the whitish warty/scaly-capped types in section Lepidella, some of which are dangerously poisonous. One dependable trait for the Chlorophyllum species is that the ring on the stalk may be detached and slid up/down the stalk. I'm pretty certain this one is not a Prince, or any other type of Agaricus. These types all have brown spore print, generally dark brown.
Bishboshjosh Posted December 26, 2014 Author Report Posted December 26, 2014 Thanks Dave the helps much appreciated. The 100% was referring to how novice I am to all this
4rum Posted December 27, 2014 Report Posted December 27, 2014 Very good photos. I'm a novice too. Hope you had a good walk in the woods with your pooch.
Duggstar Posted December 27, 2014 Report Posted December 27, 2014 Dave, the double edged ring would rule out C. brunneum would it not? And the C. olivieri I find would have a longer, more slender stipe, and a more fibrous scales on the cap. So assuming the spore print turns out white, I would call these Chlorophyllum rhacodes. Would you agree, Dave?
Dave W Posted December 27, 2014 Report Posted December 27, 2014 I agree Duggstar, probably C. rhacodes. I'm not familiar with C. brunneum, except that I know it's primarily a western NA species that resembles C. rhacodes. As for rhacodes/oliveri, I'm still trying to understand the macro-differences. My point is this. When discussing mushroom ID with a beginner, I think it's good policy to mention a range of species which qualify for consideration. IMO, the goal is to help a person develop an appropriate mind-set, as opposed to pinpointing a particular species via photo. Even when I am fairly confident about the ID for some photographed collection, I try to mention a few similar types to check. In fact, for this thread I should also mention that some smaller difficult-to-ID parasol-like mushrooms (true Lepiotas) some of which are dangerously poisonous. Agreed, 'rum. Excellent pair of photos to begin this thread. Bishboshjosh has managed to capture a range of observable traits within a pair of nice photos. In particular, the entire stem with annulus and base is seen.
Bishboshjosh Posted December 28, 2014 Author Report Posted December 28, 2014 After a closer look and the info from you guys I'd say Chlorophyllum rhacodes as the ring on stem can move freely the spore print is white and the flesh bruises a reddish colour . after comparing pictures from the other parasoles more closely the differences are quite apparent.
Cedric Posted January 12, 2015 Report Posted January 12, 2015 Looks Like Rhacodes to me, but as you have been told, careful with the small Lepiota types. As a rule, don't pick any Lepiota under 15 cm when fully opened. Cheers
