Exidiopsis calcea - perhaps

Post by Steve » Sat Apr 23, 2016 6:09 pm

Found at Longshaw, Peak District on a stick under a large elm, but not necessarily belonging to it as there are other tree species in the vicinity. The crust is very thin, less than 50 um thick, a few sq. cm in area, very tightly attached, hardly changing when soaked in water for several hours, and extremely brittle when bone-dry. This made it difficult to section the fungus. I made squash preparations. I managed to find a few hypobasidia with epibasidia, but there were very few. Also, very few spores were dropped overnight, they are a bit larger (18-23 x 6-9) than those described in Fungi of Switzerland, but I wasn't able to measure an adequate number. They are somewhat variable in shape as shown in FOS. Some extraneous crescent shaped spores were also dropped.
