Summary[edit]
| Description |
Amanita umbrinidisca (Murrill) Murrill Image location: Millersylvania State Park, Thurston Co., Washington, USA Very interesting collection. Looked very similar to Amanita augusta, only lacking the yellow cast to veil and stem. Very thick, large, meaty specimens-largest fruiting body was well over 12cm across for cap. Cap patches are dark grey and adhered to cap more so than A. pantherina or A. gemmata. Young specimens were deep yellow with an olive cast throughout caps. Volva=double collared. Fruiting directly beneath young Western red cedar and mature Douglas firs. Added images for canopy type. Harvested 3 fruiting bodies for home herbarium. Umbrinous central disc=darker brown and depressed on mature caps(intensified to nearly black upon drying/dehydration). Available for further study/analysis/sequencing. 12/3/18-Sending out vouchering samples to RET on 12/3/18. Retaining remainder of collection in home herbarium storage.. Updated 12/19/18: Performed microscopy with Celestron Digital scope. Spores=ellipsoid. Images added. Lamellae/Basidia analyzed. See added images. Will hope to get a clearer look at clamp connections(or lack thereof)/basidia, etc. in the future with more powerful equipment. Recognized by sight: http://www.amanitaceae.org?Amanita%20umbrinidisca
