I made sure to travel with a dehydrator throughout the entire trip, which was just enough to get everything back to SFSU in time for re-drying. I now pack each bag with indicating, non-toxic silica gel to keep an eye on moisture levels. This proved crucial during the last trip to Ecuador.

The eucalypts are indeed introduced, as are various pine species, both for timber. Each are now widespread and form an integral part of the economy, urban and rural alike.

I’ll try to bring this and several other Malagasy and Neotropical Amanita specimens to Maine this August.

Beautiful creatures, Danny.

I think these would probably be in section Lepidella.

I suppose you are prepared to keep specimens dry while traveling in Madagascar.

What a wonderful opportunity for mycology.

The Eucalyptus are introduced are they not?

Very best,

Rod
