When: 2009-10-12

Collection location: Luzerne Co., Pennsylvania, USA [Click for map]

Who: Dave in NE PA

No specimen available

These were collected at the same site as obs 26412, but not by the exact same tree (all Norway Spruce on a lawn). One small patch showed very little yellow (light to almost white) and another patch about 12 feet away showed some yellow, but not nearly as much as the yellow ones I saw last week (same day as 26412 was collected). Note that the yellow ones pictured here appear to be fairly newly emerged and the very light ones seem to be a bit older. Also, there was a heavy frost last night, and there have been a few other mornings during the past 10 days or so when frost formed. So, I’m wondering if perhaps the combination of frost and sunlight may act upon the color of the fruit bodies as progressive bleching agents. This could be offered as a potential explanation for why white and yellow ones comingled last week. For the yellow ones may have emerged just after a frosty period which had produced an effect upon the white (formerly yellow?) ones. The less dramatic contrast in color amongst the specimens in the collections pictured here suggest that the fruit bodies may have been affected to different degrees.
