Found in grass and moss under oak in the area just below "mushroom vale." It had not rained for until a brief but good 1-hour dousing yesterday. The ground was still a bit dry, and based on the lack of chanterelles I think it would have been thoroughly baked if we'd come before the rain. Four specimens were found. This observation is one of the younger ones. The older one has been moved to its own entry (observation 243109_) for the sake of thoroughness. I have no doubt they are all the same even though the older one was found 10 feet away from the others, by the trunk of the tree instead of the drip line. First things first: this is an intensely desirable mushroom, with the sort of scent and texture that makes boletes so much fun. The older one is slightly less dense than the younger specimens, but it is still very firm and "cheeselike" without being sticky. All specimens felt oddly heavy and cool in the hand. Cap and stem are red over yellow. Pores are bright yellow and very, very small. Tube layer is exceptionally thin, approximately 1 mm deep compared to the 9 mm context. Cap is 5 cm in diameter. The cap context was pale yellow, the stipe context full yellow, and the base yellow with a heavy amount of red from larval tunnels. The chemicals had a stronger result at each level. Lots of spots and lines on the stipe, but nothing at all like a pattern of reticulation. Taste and smell unremarkable but really good. **A note on lighting* The photos taken on the table are about 2 hours after picking. Except where noted, it's natural light on a very overcast afternoon. *A note on chemical reactions_** All the ammonia reactions were very weak if they existed at all. The KOH reactions were more profound, but still not striking. Iron salts had a very ready reaction, which differs from other "bicolor" observations such as observation 242587. All of the chemical reactions got stronger as the test moved from cap context to mid-stipe context to lower context. Ammonia on Cap Skin: Yellow Ammonia on Stipe Skin: Yellow Ammonia on Pores: Yellow Ammonia on Cap Context: No reaction Ammonia on Stipe Context: No reaction, or might have darkened a bit in the lower portions. KOH on Cap Skin: Yellow. KOH on Stipe Skin: Orange KOH on Pores: Orange. KOH on Cap Context: Yellow to pale orange. KOH on Stipe Context: Full orange in the yellow parts, and red-brown further down where there are red larval tunnels. FeCl3 on Cap Skin: Olive green. FeCl3 on Stipe Skin: Light olive green. FeCl3 on Pores: Olive green. FeCl3 on Cap Context: Pale olive green. FeCl3 on Stipe Context: Dark olive green.
