Observation 221679: Amanita sect. Validae (Fr.) Singer
When: 2015-11-04

Notes: One mature and one very immature fungi together on verge of Eucalyptus forest. Some recent rain and beginning of Fungi season. Mature specimen had curled splitting cap with evidence of warts. Gills were wide and loose. Stipe broke away from the pileus easily. No identifiable aroma. Although the Cap was wet (raining), it felt slightly slippery it was not sticky. The stipe cut easily and was not hollow. The Younger specimen shows a better degree of wart formation and colour. Both Fungi were well secure in forest soil.
Stipe of mature fungi displays yellow colour from top of stipe to base. At the base area which was slightly bulbous there appeared to be some woody material forming the main internal base region. The smaller fungi when bisected showed a similar texture and woody colour when cut to show the internal base area. Still trying to get a spore print and will do a scope if needed.

With the 100x objective lens, you will have to use oil.

Summary

Rod, Thanks for the helpful tips. Normally I can get some spores separated and at 100×. This proved a bigger task with this specimen for me. You were right with the Melzers, and it did make a difference with the clarity. For some reason after X40 I was unable to get a clear spore image. The slide seemed to be too dark although I tried all the variables. More practice and patience I imagine. I didnt go to oil, maybe I should have.?? kk

I suggest gettin a shot of a few spores away from a piece of the gill.

With the addition of Melzer’s reagent, removing basidia from the background makes for less confusion between the business end of a basidium and a spore.

Very best,

Rod

I did some scope work only using water as the reagent. The images are not anywhere as good as I would like but they may help with ID.

Hello, Ian. Thank you for the note calling my attention of this observation.

I agree that it is possibly an Amanita.

Some information regarding spores’ reaction to Melzer’s reagent and spores’ size and shape would be helpful.

Very best,

Rod
