Thaxterogaster causticus, formerly known as Cortinarius causticus[1] and commonly known as the caustic webcap,[2] is a species of mushroom in the family Cortinariaceae.
Description
The orange,[2] hygrophanous[3] cap of Thaxterogaster causticus is about 1.5-4.5 centimeters in diameter. It starts out conical and usually becomes umbonate in age.[2] The gills start out creamy or white-colored, before becoming brown as the mushroom gets older.[4] They are adnexed and often notched.[2] The stipe is about 3.5-7 centimeters long and 3-6 centimeters wide. It is white and bruises yellow.[4] The spore print is rusty brown.[2] Both the cap and stipe of this mushroom are slimy.[3] There are several similar species, including T. vibratilis, which is found in Europe.[2]
Habitat and ecology
Thaxterogaster causticus grows under conifers, such as pine,[3] hemlock, and fir.[2] It is found in coniferous forests[3] in the Pacific Northwest.[2]
