Laccaria

Laccaria amethysteo-occidentalis   (California) Frequent under pines

Laccaria bicolor    (California) Abundant under pines. L. bicolor should have copious amounts of purplish mycelium at the base of the stipe. L. amethysteo-occidentalis also has that feature, but the spores are sufficiently different to allow easy separation microscopically.

Laccaria fraterna   (=L. lateritia)  Most frequent under Eucalyptus globulus, but appears under other exotic hosts as well.
Same patch -- changing dramatically in age. A real chameleon...
Spores: 8.5-10(11)-8x10µ globose to subglobose, moderately echinulate	Basidia: bi-spored

   
Laccaria laccata v. pallidifolia    This is a common Laccaria that can be found under both hardwoods and conifers. The version L. laccata v. laccata apparently is a rare species Worldwide that has not been collected in our area.
