Observation 237835: Auriscalpium Gray

Notes:
Growing in wet lowland alien forest on unknown downed wood (possibly Kukui Nut, Aleurites moluccanus). I thought this was Schizophyllum commune from the top, there are not many hydnoid fungi reported from Hawai’i as far as I know.

Odor: moderately fungal/mushroomy
Taste: delayed (10 seconds) peppery taste.

I know the microscopy isn’t great…working on it.

and borrow his Melzer’s. unless he’s completely abandoned his master’s degree for whittling, moonshining and sign shooting, he should still have some reagents and at least a hazy idea of how to use them.

Thanks for looking into this more…

The macro description does fit well for A. villipes (The spines are more white/cream as opposed to pale brown, but no biggie) except for the stipe. Definitely no stem on these.

Yeah, I have been struggling with the scope; particularly w/ pale spores. I don’t have stains, I don’t have Melzer’s, and I’m assuming I have poor to mediocre technique! The close-up images were done 100x w/ oil.

Maybe I’ll have to bother Lynx for a lesson and supplies advice (when I was more motivated last year I ordered congo red and methylene blue online but was told they would not ship to Hawai’i). If you have any more input/advice let me know.

make out some ornamentation in the outline of these subglobose spores. so long as they’re also amyloid, we’re heading in the right direction for Auriscalpium or something in that neighborhood. the trouble is that Auriscalpium might always be stipitate, and I see no stipes here. I think that this and many other observations on the site could be A. villipes, and that the description of that species’ manner of attachment in the literature might need some updating to include less stipitate forms. or it could be something else entirely. a pileate to effused-reflexed cousin of Aurisclpium is Gloiodon, but members of that genus are much darker with strigose cap surfaces.

in addition to checking for spore amyloidity and measuring 20 or more of them, I would also check for the presence of gloeocystidia in the hymenium.

to determine presence/absence of amyloidity and/or fine ornamentation. be scoping at 100x w/ oil.
