When: 2019-10-16
Collection location: Lincoln Co., Maine, USA [Click for map]
Who: jtibbs
Notes:
• Pileus: 1-4cm; margin translucent striate when moist, hygrophanous with a separable gelatinous pellicle, sometimes turning blue
• Stipe: 2-6cm; An annulus/ring zone often present, streaked with blue (or black) in mature specimens or soon after collection. Other regions of the stipe, especially the base, usually turn blue after handling.
• Microscopic: Spores dark purplish; I have not measured the spores or the cheilocystidia, pleurocystidia absent.
• Habitat: Mulched/wood-chipped area adjacent to a river, woodchips are softwood (probably white pine); occurring in patches with a max distance of ~200ft apart. Shade and slope is variable between patches.
The thin membranous partial veil/annulus isn’t always present in mature specimens, seems to depend on various environmental factors or maturity. Sometimes the veil is stuck to the cap margin or stuck to a neighbor’s cap.

Has caerulipes been recorded on softwood? jtibbs reports it on softwood, likely white pine.
…. the cheilocystidia here are not a good match for P. ovoideocystidiata, the neck is too long and the shape is mostly lageniform with a long flexuous neck.
P. ovoideocystidiata has globose, pedunculate or subpedunculate cheilocystidia.
This looks more like P. stuntzii.
This photo of the cheilocystidia is not good, I know. It is the best I can do for now with my scope at home. I will try to get some better photos and measurements on here soon. The cystidia are tiny, abundant, and they have shoulders with long neck-like projections.
Does P. ovoideocystidiata usually have a separable gelatinous pellicle?
Are you able to post some photos of the cheilocystidia?
Yes. I have found P. caerulipes on softwood mulch. https://www.inaturalist.org/observations/5700751
