As humans spread invasive species around and alter fire regimes, we change the basic functioning of single keystone species, which ultimately radiates to other species. With whitebark pines declining from 40%-90% throughout their range, these high elevation regions are drastically being transformed. Grizzly bears depend on these fatty pine nuts to get them through the harshest winter months when little else is available. As these tree populations decrease, the fight for survival intensifies. It is time we all think about plant conservation and our role as humans in protecting these truly wild places. I’m here to remind you, and remind myself, that the struggle for survival in Yellowstone is ramping up, and that the decimation of one species radiates throughout the food web, which increases competition, which unfortunately increases the rates of human-bear conflicts.

The species featured in today’s edition of Fungi Friday is more cryptic than those deadly looking Amanitas. Galerina marginata not only varies in its appearance, but it looks like a few other edible species that also grow from woody debris. The forest floor is an incredible place, but it must be respected. Death by mushroom is not the way you want to go.

a.) Hypomyces perniciosus on Agaricus bisporus at 3 days. b.) A germinated chlamydospore ofH. pernicious. From Zhang et. al 2017.
In this weeks edition of Fungi Friday learn about an economically important fungal parasite and find out why Hypomyces perniciosus doesn’t infect the mycelia of Agaricus bisporus, but readily parasitizes its aboveground tissue.
