just a couple days after reading your comment about white Clitocybes often being hygrophanous, a new fruiting appeared. Links below are obses taken over two days. All of these mushrooms were found either singly (first link) or in small groups in a different part of my property than the ones in this obs (142925). There are very few mushrooms fruting around here right now (several hard freezes), so given the similarities in macro-traits, the matching spore sizes, and the occurrances in grassy habitat, I believe these all represent the same species as obs 142945. Note the color variations brown/tan/white. These linked obses were encountered during the morning, in chilly weather (couple hours after thick frost), a day or so after a soaking rainfall. So I believe the deviation from ivory white seen on some caps is attributed to moisture retention. Interestingly, one or two small brownish ones did not fade upon being laid indoors for several hours. Obs 142945 was made during dry warm weather, August as opposed to November.

No distinctive odor noted.

I believe C. dealbata subsp. sudorifica is a good fit for all these obses. Note that some macro-characters for this species differ from the European C. dealbata. Also, none of the sources I have used mention C. dealbata subsp. sudorifica as being hygrophanous.

Several sources I have used…

list Clitocybe dealbata subsp. sudorifica as a NA species, including the Audubon guide and a few newer guides. Apparently, this type is similar to, but not the same as, the C. dealbata of Europe.

I am interested in learning to classify as many of my local fungi as possible, and maybe some others that I happen to run across when I travel. I do not engage in serious research, but I do like to use names whenever possible. To my knowledge, C. dealbata subsp. sudorifica is a name that very well applies to these small white Clitocybes that occasionally inhabit different areas of my lawn. If anyone has other names to suggest, then I welcome this input.

The one thing that bothers me about using this name is that these small white Clitocybes I find exhibit variation in gill spacing.

If you are going to work on Clitocybe you should record things like smell and whether they are hygrophanous or not (Even the all white species can be if you pay enough attention). Unfortunately even then, I’m not sure which literature you could use that would help much. Does C. dealbata even occur in the states? I have a hard time wrapping my head around the names and species concepts in this group….
