When: 2013-05-09

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

Who: Phil Yeager (gunchky)

No specimen available

Most of these morels were found under a mature, still healthy apple tree in an old orchard. Twelve were under one tree, and three were under a different tree. The other trees in this orchard were unproductive. The photo of three morels together was taken in a different location and they were found near mayapples growing near ash trees.

a specimen of MorchALa TONDORApes.

As for the Morchella, looks like spore size/ratio for M. esculentoides, M. diminutiva, and M. virginiana are all very similar. So you probably will not achieve closure on a species ID based upon spore size. It is my understanding that M. diminutiva and M. virginiana may be reliably seperated only by DNA analysis. I’ve been calling these small forest yellows “diminutiva/virginiana types.”

zoom in on the tree in the bottom photo and see if you can recognize the person under it. Having fun with a new camera.

to get spore prints and sizes to post. Perhaps this will help to identify the specimen to species.

that I left last thursday, did some research and reached the conclusion that the tree mushrooms in the third from last photos are M diminutiva, not M. Virginiana, due to the location where found and the small size as indicated by the metric ruler placed to the side. Mistook these three for M. esculentoides.

you read my notes correctly

the three morels in a group were all found within eight feet of one another. I left some ther to see how much bigger they can grow. I also noticed that the ridges and pits were more elongated than those found in the orchard. Hopefully I’ll know more by Fridays meeting.

Phil, I’m guessing that…

the three small ones in the bottom of the group photo came from around the ash tree. These three (at least the two smallest ones) are likely a different species than M. esculentoides. They are either M. diminutiva or M. virginiana. The main difference (aside from size) is that these diminutiva/virginiana types have longer slot-like pits. Although I do find what I believe to be esculentoides in hardwood forests, the diminutiva type is more common in this habitat.
