JGI 1000 fungal genomes is sequencing a close relative M. procera; partial text below:
Macrolepiota fuliginosa (Barla) Bon, is a litter-decomposing basidiomycete belonging to the order Agaricales. Due to their morphological similarities it was originally classified as a variety of Macrolepiota procera (Macrolepiota procera var. fuliginosa (Barla) Bellù & Lanzonidue). M. fuliginosa grows preferentially in Fagus, Quercus or conifer forests in southern Europe, and plays an important role in the breakdown and chemical conversion of litter components to simpler compounds. The sequencing of the M. fuliginosa as reference genome within the framework of the ‘Metatranscriptomics of Forest Soil Ecosystems’ project will provide new insights into the diversity of forest fungal communities and their role in nutrient cycling.
only… because it’s very similar to ours (macroscopically). I saw two today that I will upload. In my opinion “M. procera sensu American” would be a good name, for now as it’s easier to change the name in the future.
to back off to Genus, or group or even family for species that can not be determined by a photo or are not known from North America (in the case of a European named species). I am not happy with provisional names (but I have used them at times) and I don’t like calling it what it is not. See all the changes to Bisporella citina. Patrick is correct. There are many European names currently in use. It is a matter of opinion whether to use the European name, or use group,or sensu American authors which is what I like to use at forays.
There is no right answer. It is unfortunate that the upheaval in this time period leaves us nameless for popular edibles like parasols, chanterelles and morels. When the dust settles years from now, there will be names. In a forum like this, many times we will have to settle for a genus or group name. As in the Mycoflora project saying, “without a collection, it is a rumor”… And without a description it is nameless.
for a discussion of the naming convention on MO as it applies to NA versions of M. procera.
The problem is we don’t have a name (or names) for the common Eastern North American Macrolepiota. I prefer genus to group in most cases but neither is satisfactory. I do know that whatever the name turns out to be, it is one of the very few mushrooms that I consider a choice edible! The slight snakeskin look of the N. American species is variable.
Do you think we have the ID wrong or do you take issue with the “group” name?
I just noticed that there are MO postings of M. procera from NA. I rechecked M. Kuo’s site and he describes it from east of the Rocky’s as does Roger’s Mushrooms website. So it looks like the books are still calling this by the European name at present.
in the same way we’re use prefixes like “sub” or “ameri” for some species that we know are probably not the same as the European species but are the NA version?
At some point this would have been called a Lepiota. Otherwise, Chlorophyllum brunneum and Chlorophyllum rachodes are not synonyms, but neither show the snakeskin stipe pattern. As for M. procera it has not been shown to occur in the United States as far as I know. I think this a known, but undescribed eastern taxon found all the way into New England.
