DD532 - Leucoagaricus rubrofolia nom. prov. Originally one of two photos for Observation 1038, but later found to be a different species. . From Dr. Else Vellinga: DD532 is a mixture of two species; most specimens are what Dr. Sundberg called L. rubrofolia; there is one specimen of L. roseifolia. The names are similar, but the species actually are quite different. L. rubrofolia is quite close to Leucoagaricus croceovelutinus from Europe and L. haemorrhagica from Australia and forms a group of species separate from species like L. roseifolia, L. flammeotincta, L. badhamii, L. cupresseus etc. The differences are manifold, very striking is the fact that the reddening reaction in L. rubrofolia is that and that the red does not change into the dark dirty blackish colour which so spoils the finds of L. flammeotincta and the such. A drop of KOH or ammonia has a different effect: orange-red in L. rubrofolia, and greyishgreenish in the others. Microscopically, again a wide array of characters; the spores in L. rubrofolia and its allies have a small but persistent papilla at the apex, giving them a very characteristic look. By the way, the name L. rubrofolia has never been published officially. I am still not 100% sure whether there are enough morphological characters distinguishing it from L. croceovelutinus to warrant a separate species, and if so, i would never use the name L. rubrofolia, as i think the name should refer to the pileus, and not to the lamellae.
