Observation 160203: Leucocoprinus fragillinimus

Leucocoprinus fragillinimus

This Fungi was found in a Eucalypt forest, located on the East Coast of NSW Australia in the Yarrahapinni State forest, near Grassy Head.
Several individual specimens were found, (10), but in only this area, and over an area searched of about 250mtrs. Most of the specimens were almost mature or mature. Recent 4 day medium rainfall I believe had encouraged the show of fruiting bodies. All specimens found were growing in the substrate , (decomposing matter),and the humidity was high and temperatures were in the High 20’s(Celsius ) to low 30’s. All specimens sighted were in good condition and were incredibly delicate.
The caps were opalescent, easily damaged, and off white/yellow in colour, tinged with yellow specks and with the central area of the pileus, yellow. The gills were close, and showed some remnants of an earlier stage in growth. A distinct annulus was evident on all specimens sighted. The stipes tapered slightly from the cap to the base, which in some cases became bulbous. The Caps were almost 5cm across and the stipes about 10cm in length, (approximately.)
A cap was placed on paper at the site for collection of spore. At home the deposit of spore was scraped off the white paper and placed on a dry slide, initially.
The first Image (5769) loaded, represents this example loaded. I must mention that when scraping the pores off the paper onto the slide, there may have been some paper scrapings included. It was impossible to relate with any confidence the spore colour, although the Cap showed yellow specks.. I had previously loaded similar images.(7762 & 44699), which were both identified as:
Leucocoprinus fragillinimus (Two other specimens identified with the same name were loaded by Dan Molter 50755 & Erice Urbanovitch CureCat 21561.)
I found it very difficult to find any images in my library for, (Leucocoprinus fragillinimus) but, was able to find a reference to ..>> :[ Leucocoprinus austrofragilis Aberdeen, Lepiotoid Genera (Agaricales) South-eastern Queensland 11 (1992)].. in Fungi of Australia Volume 2A. Catalogue and Bibliography of Australian Macrofungi 1. Basidiomycota p.p.
No descriptive data accompanied this reference. I presume the two names are referring to the same species?.
Images 5771, 73, 74, 75, 76 and 5778 inclusive are taken from spore deposits.
Image 5779 is micrograph of section cut from pileus.

Not sure what was going wrong, but — naturally! — it’s working okay for me right now. I make it a policy not to try to fix bugs that I can’t reproduce. :)

Add a name?

May be Leucocoprinus austrofragilis.
Nathan, for some reason I was unable to add another suggested name? Tried several times without success, hence the note.
The site didn’t reckognise “Leucocoprinus fragillinimus” when I originally created the file although it had recorded the name previously. (see notes).
Maybe the name has been depreciated?
