Lycoperdon molle

I have looked at this puffball extensively under the microscope. Based on these characters, I am going to call this puffball Lycoperdon molle. In addition to these characters, this specimen is missing characters needed to call it V. curtisii.
So:
The exoperidium has remnants of it’s scurfy furfuraceous minute warts. It has a chanbered subgleba (no diaphragm). It has Lycoperdon type eucapillitia with pores of varying size – medium and small. The water and KOH mounts have an abundance of sterigmal remnants. The spores are globose with asperulate verrucae and broken pedicel remnants. The spores are roughly 4.8 × 4.8 (LxW). This size fits with the European keys, but is a bit small for the Arizona key.
