Rosellinia corticiumObserver
maricel-patinoDescription
Spores have a slit from end to end and a sheath. Ascus has a strange design at tip. Paraphyses end very thin towards base and have drops. Each unit was around 1.25 mm wide. Spores: 8.6-9.8 x 24-32 um. Asci: 14.8 x 148-160 um. There was some scanty brownish mycelium at base, turning dark brown and almost disappearing when units get too close. On hardwoods.

GAB290; photos and collections by Aaron Nelson; used with permission.
growing out of ground and along base of buttessed roots of an okoume tree. The stromata were in 3 adjacent gaps between the butressed roots. When I dug into the dirt where the Xylaria were growing the only things I found were active termite tunnels and some small roots but not very many of the latter. i took pictures of the termites/tunnels in pieces of dirt that I dug up. The dirt is dark, dense, and strongly bound together. There's termite frass tunnels on the butresses.

Growing in soil under Pinus virginiana. Spores are considerably larger than what’s described from the neotype collection, so I would consider this a close relative.

Under Pinus taeda. Smells a bit like stale bread. Soft and squishy volva, a similar texture to marshmallows. Note the pileus margin becomes striate with age/drying. I believe this could be A. subphalloides. (http://amanitaceae.org/?Amanita+subphalloides)

alan_rockefellerDescription
Found by SEmushroomHunter, ID’d by Workman, who says "Spores: subrhomboid 6.6-8.2 microns
Cheilocystidia: 16.4-22.3 microns
Pleurocystidia: absent
Psilocybe weilii has smaller spores and abundant pleurocystidia. This specimen keys out solidly as Psilocybe caerulescens which is not unknown in the SE United States. P. caerulescens was first described by Murrill from Alabama in 1923 and as far as I can tell it hasn’t been reported from anywhere in the US since. This sample could be a remnant of that first described collection. Samples should be sent to a herbarium to officially document the find.
The only reason this sample was determined to be different from P. weilii is because of the microscopic examination. The two species are macroscopically virtually indistinguishable. I suspect that many of the “weilii” collections are actually unrecognized caerulescens or a mix between the two species. Further microscopic examinations of various collections is needed."
