Three images. A truffle-like species which is unusual in that the spores form in a space around an infertile core. The core is believed to be highly in nutrients which is the reward for the mammal that finds, eats and disperses the species. In other truffle-like species virtually all the inside of the fungus contains fertile spore producing material.
About 30 growing in chip mulch with weed mat layers in home garden. Probably many more 'eggs' because we only checked several square metres. The spores are in the brown goo on the inside of the lattice. No noticeable odour.
Several images including close up of the pinkish brown spores caught up in the gills. Superficially like Cheimonophyllum candidissimum which has white spores and also like Crepidotus variabilis which has a watery texture and is not as furry with gills that quickly turn brown.
