Observation 50501: Amanita augusta Bojantchev & R.M. Davis

When: 2010-08-12

Collection location: Point Reyes National Seashore, Marin Co., California, USA [Click for map]

Who: Adam Singer (adam)

No specimen available

Only found one speciman though I looked hard for more: Cap 6.5cm diameter has a universal veil remants that were ochre-yellow colored and covered most of the cap as classic little warts or nodules. Cap itself is dark brown, almost olive or wine brown, convex. The flesh inside is creamy white but with lots of yellow tinge. Gills: many, thin with some short (half length) lamellulae around margin but not between all lamellae. Margin/edge slightly in-turned/curved-in and edge has teeth composed of gill edges. Stalk is 8cm tall, 2cm thick at middle, bottom “bulb” is about 2.5cm and was white with light brown hairs in a wavy pattern. Bulb was bulbous with either the sac glued to where I could not distinguish it from the flesh of the bulb or not there at all (or I missed it). Had a huge, thick annulus that formed a skirt and it was high up on the stalk, very yellow and had striations as if yellow spore had dropped onto it but the spore print was white.

Md pg. 267 15 – 16 – 17 – 8 – 19 – 20 – 21 = a. aspera (franchetii).

First image has the a. francheti sitting on a suillus.

Sorry for the poor photo quality, hope to do better with a real camera next time.

the amanita is sitting on a suillus to prop it up a bit – that makes it look a little confusing, sorry ’bout that. The franchetii is covered in warts.
