Collection location: Malibu Creek State Park, Malibu, California, USA [Click for map]
The date is only accurate to the month.
Found at the Chumash Intepretive Center.
When I first found this specimen I wasn’t able to even place it to genus. This specimen is young enough that it had few if any mature spores. The relatively large size caused me to discount Inocybe as an option. Subsequent collections finally allowed me to conclude that this had to be the correct genus.
This Inocybe is actually quite common in the Los Angeles area. After initially identifying it as I. jurana using Mushrooms Demystified, I have read further keys (Fungi of Switzerland & Nishida’s CA Inocybe Key in Mycotaxon) and consulted with various experts (Florence Nishida and Patrick Matheny) on this group and concluded that I. adaequata is the most appropriate name pending more research.
