Observation 141698: Amanita sect. Lepidella sensu Bas

Notes:
This specimen was found (not by me) during an FPP foray with the NJMA. That’s why I can only comment on morphology that remained intact by the time I picked it up from the ID table.

This is a miniature specimen from a section that usually produces giants. It’s measuring only 5 cm in height. The cap has a diameter of 3-3.2 cm, and the stipe is 6 mm thick at its narrowest section (the middle).

The cap volval material consists of pyramidal warts with brownish tips that are localized to the inner half of the disk. The warts get progressively flatter away from the center. The carrot-shaped, rooting bulb contributes 1/3 to the total length of the stipe. The annulus is superior; it has an irregular margin decorated with “icicles”. The fruitbody sustained larva damage, and the tissue around larvae tracks is stained brown. There also appears a single smudgy brownish stain from handling on the stipe (top picture).

The material is available for further scrutiny.

Another memory lapse on this one, which makes sense as I wasn’t the one who collected it, but I am almost certain it has to be obs 286409 – found almost 4 years to date later. The diminutive size is an important clue.
Since this is clearly not a common or commonly encountered species, judging from only two records from FPP posted to MO (to my knowledge), I am willing to bet both collections came from the same spot on the sandy road leading to Chatsworth Lake.

Thanks Igor,
