Observation 202586: Lactifluus (Pers.) Roussel

This particular mountain and surrounding area of different Eucalyptus Forest types never ceases to amaze me. Every visit it throws up something new and exciting. This particular Fungi I do not remember recording before. It was found growing on a Moss covered bank in a semi rainforest area of Eucalyptus and associated flora. The Cap was medium brown and the fungi was mature and easily removed from its habitat. The fungi was delicate and the wide gills were brittle and easily broken. The stipe was short and formed onto a Shell shaped Pelius. Only the one specimen found in the area. I was amazed when I turned the fungi over to find beautifully formed gills ,(not pores as I had expected), and the unusual dark brown thin line running the full length of each gill .The area was damp from previous two days of constant rain. I often see very much smaller seashell shaped fungi on this type of bank, but never as large and magnificent as this specimen. Worth noting was the collection of matter at the narrow end of the gill formation that was also unusual. It made my day……..

If you doubt that this is a milk cap Ian, let those spores convince you. If you have Melzer’s solution, a slide of spores mounted in water w/a drop of Melzers will be amyloid (blue) and ornamented: either discreetly warted or covered by a reticulum.

These spore characters (amyloid and ornamented) are true for all Lactarius and Russula species, no matter how bizarre their forms!

Ed Thankyou.

Thanks for the comments and link. I am always looking for that added bit of info, especially like what you have been kind enough to provide. This was a one-off you might say. I have logged several Lactifluus, but none like this find. I will read the paper today sometime. Again Thanks. kk

Hi Ian,

Here is a link to a paper discussing Australasian species of Lactarius subgenus Gerardii, which has been transferred to the genus Lactifluus. There are many odd Lactifluus, including pleurotoid forms. I cannot tell if yours is truly pleurotoid or if it just looks that way due to degradation. However, overall morph features point to Lactifluus – crumbly basidiomata, velvety pileus, dark gill edges. Also, remember that “milk-mushrooms” don’t always exude milk. Their capacity to due so is dependent on environmental and other factors. Hope this helps. Let me know if you have any more questions!

ID Lactifluus

I did not see any as per quote:>{Lactifluus is a genus of fungus commonly known as milk caps, as they often exude latex (milky fluid) when cut}? Is there more info on your I.D. please as this fungy is a new find for me, and did not display Milkcap’s tendencies.. Thanks kk

wow : D
