Observation 190571: Amanita citrina f. lavendula group

When: 2014-11-26

Collection location: Juliana Trail, Longview, Gregg Co, Texas, USA [Click for map]

Who: L G Price (LG_Price)

No specimen available

I found a group of mushrooms with two distinct types. Type 1 smaller and Type 2 larger, more warts on the cap. Otherwise the two types are very similar and per most field guides would be identified as Amanita gemmata. I’ll keep to that unless I can find out more.

This observation is for the smaller, type1. The slender one on on the right of the 2nd photo. There were two of this type, almost identical in all aspects.

See Observation 190382 for a description of the larger mushrooms.
