I spent 50-50 percent of my time between Mexico City and Tepoztlán Morelos but most of the recolections I do are Morelos based. I haven’t visited the Universidad Autónoma del Estado de Morelos Mycological Herbarium, but I’m planning to do it as soon as I have some free time. Special attention on Amanitas this season!


too little info to ID to species here.

not only bisporigera has a “thin stem” or a “white cap.”

You’re welcome, Alejandro.

I look forward to hearing more about your material. Are you based in Morelos?

There is a very interesting Amanita that was found there in the past. It is one of the species that seems to be amycorrhizal.

Prof. Montiel-Arcos collected this material in 1991 and showed this material to me in the late 1990s.

From photographs, it looks like A. macerisolum:


Very best,


I will describe and photograph them better this season

Rain season in México is not too far, I will document my observations better this year, and will try KOH too, I’ll ask for your opinion soon.

Thanks for the comments

That is something that I don’t know about.

Some people have described a “chlorine”-like smell for some of the white Phalloideae in the eastern U.S. I have never detected that. It could be that I don’t have the right genes. The smell I associate with the white “destroying angels” is the sweet smell like carrion that the fruiting bodies acquire as they begin to age. French authors sometimes say it is the smell of “decaying honey.”

Very best,


Cap surface white

Like in the other observations, didn’t taste but I did noticed after handling this one http://mushroomobserver.org/231537?q=2iSBz that it started exuding a transparent liquid with a very strong “chemical smell” (not sure that makes any sense)


Was the cap surface white? sordid ivory? gray-brown?
