Henri Report post Posted November 30 Can you help me to identify this mushroom? It was growing on lawn under oaks in Finland this September. Quote Share this post Link to post Share on other sites
Dave W Report post Posted December 1 Nice photos of interesting mushrooms. First thing that came to my mind was genus Lentinellus. But closeup of gills shows fairly even edges (not serrated/jagged), which I believe eliminates this from consideration. Genus Cantharellus was my next thought. C. pallens is a European species that is colored somewhat like these. But the gills seen in these photos are not strongly forked. (Lots of short gills that taper near the longer ones but not truly connected together.) Interveining is present but not prominent. Genus Cuphophyllus comes to mind. C. canescens and C. colemannianus are each somewhat similar to this, but I think neither species is the correct ID here. Unless something else occurs to me, either of the latter two genera mentioned is the best guess I have. Quote Share this post Link to post Share on other sites
Henri Report post Posted December 1 Thanks Dave for your effort. This one is a bit of a mystery mushroom. There has been some timid suggestions of some sort of lobed form of Pleurotus ostreatus and also Hohenbuehelia petaloides. But no one here has actually seen anything like it before and I was thinking maybe some North American mushroom... Thanks, Henri Quote Share this post Link to post Share on other sites
Dave W Report post Posted December 1 I briefly considered Pleurotus. But the gills look wrong for this genus. Hohenbuehelia petaloides is an interesting suggestion. This would be an atypical example of the species. If you have access to a microscope, then the H. petaloides proposal may be tested. At 400x magnification, one should have little trouble locating the large pleurocystida found on a gill of this species. A smash mount of a tiny piece of gill mounted in a stain like Congo red should suffice. Maybe add genus Hygrophoropsis to the list of guesses. Whatever this is, I think it's either an atypical version of a well-known species or else something quite uncommon. Quote Share this post Link to post Share on other sites
Henri Report post Posted December 1 Thanks again Dave, I regret I did not collect a sample. Thought ID would be a piece of cake. I'll certainly have a closer look if the mushroom grows on the same spot next autumn. Quote Share this post Link to post Share on other sites
Dave W Report post Posted December 2 Yeah, I understand. Anything this distinctive would presumably key out! Quote Share this post Link to post Share on other sites
