White cylindrical rhizomorphs spike line at base. Gills attached, light creamy. Under oak, Laurel and redwood duff. White rhizomes rose up half the stipe creating zonate top in beige color. Small size is hard to place this in this category, thought it even might be Lepista subconnexa? Maybe cuphophyllus formicatus?

@caterpillarlady made this wonderful discovery last week. There are at least a hundred eggs here, some of them being laid one on top of the other. I hadn't realized that butterflies and moths do that.

But the remarkable thing here is that the mama butterfly has used a completely alien host plant: Phygelius equalis (Scrophulariaceae), which is endemic to South Africa. It's not as if this is a non-native that has established itself in the area. This may be the only specimen in the Bay Area.

But these butterflies use several host plants in the Scrophulariaceae family: Besseya, Penstemon, and Indian Paintbrush. So the butterflies accepted this South African Scrophulariaceae also.
