A few Amanitas.


Recommended Posts

To ID an Amanita one needs to see: entire base of stalk, to what degree the cap margin is srtiate, presence/absence of partial veil, ornamentation on cap surface. The partial veil aspect is the trickiest, as some Amanitas that have a pv readily lose it as the cap expands.

1st one. No pv (ring), cap striate maybe 30% of the radius. if you were to dig this one out of the ground, you would see a membranous sac surrounding a non-bulbous stalk bas (volva... remains of the universal veil). This is an Amanita from section Vaginatae. The brown color on the cap points toward Amanita amerifulva, the America "Tawny Grisette". (The Euro species is the classic A. fulva... a different species... maybe.) This group is currently being studied.

2nd one. Striate cap, large membranous volva, pv present as a ring on the stalk. Section Caesareae. Amanita jacksonii is a good possibility. There are a few other species of reddish American "Caesars".

3rdon. Need to see the stalk base and info about partial veil. A few possibilities here: A. rhacopus (section Vaginatae), no pv, striate cap, membranous volva that disintegrates into a grayish ring on the upper stalk base. A. amerirubescens (section Validae), pv present, cap not distinctly striate, base of stem with (possibly small/slim) bulb, reddish-brown staining on variuos parts.
