Author's notes

Caps velvety, becoming conical with age and often tearing in the centre. Most caps 40-60mm diameter. Stipe short and stout. Spore print white. Spores sub-globose, rough. Could this be Russula flocktoniae (based on p169 in Fuhrer's field guide)?

KerriLee you have a Lactifluus sp. it is often recorded as L. clarkei though I'd be inclined to call it L. subclarkeae (see Cheryl Grgurinovic's Larger Fungi of South Australia op. 63 under old genus name of Lactarius) or you can go with L. clarkei complex. The only problem I have with your great photos is that you treated the specimen with too much respect! If you had damaged it, only slightly of course, particularly the lamellae you would have seen th classic Lactarius exudate, in this case white. This is usually a quick way to divide the Russula spp. from the Lactarius and Lactifluus ones. These are mycorrhizal, ectomycorrhizal to be exact, so it would be interesting to note nearby tree species that it may be associated with. This appears to be a new species for this site

I have some new information to add: the stem snaps and breaks into pieces, 'chalk-like' (photo 3); and there is no apparent exudate when damaged, including when the gills are crushed. Hope that helps :)

As for identifying the host trees, I think that's nigh impossible here in the forest. There are so many trees, of many species.

Yes the stipe should break like chalk, if the invertebrates haven't trashed it, because these three general that I've mentioned all belong in the family Russulaceae. The species in this family have sphaerocysts. Simply, these are roundish cells which facilitate that classic Russulaceae 'chalk snapping' character. Trying to id this group of organisms (fungi) from photos is challenging. The additional characters that swayed my id were that the lamellae attachment is adnate, though sometimes subdecurrent for the Lactifluus subclarkeae, which fits. With lamellulae at periphery that often bifurcate or are anatstomosing, the R. flocktonae this is only occasionally so. If you look at image 3, the left hand cap edge you can see this character all the way around the perifery of the cap. Also the lamellae often become spotted with age - again in image 3, the left hand cap you can see light spotting appearing on the lamellae to the lower left. That dark brown markings on the lamellae of the right hand specimen where it has been damaged, indicate to me the presence of lacticiferous hyphae (latex containing hyphae) You should be able to see these under the microscope. On image 5 on the left hand side c half way down the outside lamella you will notice a tiny droplet. I have at times found it very difficult to find exudate in some specimens so that doesn't worry me. Hope this is of some help. As I've said id'ing fungi from images is an inexact art and I can only work on characters I can see and my familiarity with the different species. If you're still not certain I would suggest you just place it under Russulaceae which has unquestionable rigour.

Well problem solved, well partially anyway. Russula flocktonae was transfered to Lactifluus flocktonae in 2016 by Teresal Lebel et al. As I can not be definitive about the species name I've opted to just confirm it by the genus Lactifluus. Hope that is of some help.

Sorry I can't seem to remove the superflous names as I just keep getting a 'we are busy' message. If you could tidy this up for me it would be much appreciated

Thanks very much Pam. The system does seem to be struggling at the moment ... probably some technical improvements being made behind the scenes.
