When: 2012-10-10

Collection location: Moon Lake Park, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

Although I failed to excavate the stipe base (mature fruit body was fragile) the similarities to the linked obs are apparent…. yellowish ring, striate margin, otherwise Angel-like… as opposed to angelic :-)


Photo shows amyloid reaction of spores with Meltzer’s. Spore photo shows spores mounted in Meltzer’s.

Specimen collected in grassy area near hardwood border about 150 yards from where I collected obs 112833. Currently dehydrating.

Collecting mushrooms for the prupose of study adds another dimension to the hobby. One feels a part of something much larger than oneself.

Regarding the marginal striations, this is one of several observations which I believe to be sect. Phalloideae which showed this feature. Mushrooms from these Moon Lake collections also showed a collapsed annulus that had stained browinsh/yellowish; probably also due to stressful conditions. Our local autumn weather generally features temperatures that fluctuate between 20Fs and high 70Fs. Here’s another of these “striate Angels” which I collected from the same area of Moon Lake.

Thanks, David.

The material is accessioned in our herbarium and in the sequencing queue along with the other materials of sect. Phalloideae that you sent us recently.
