When: 2012-08-27

Collection location: Flemington, New Jersey, USA [Click for map]

Who: Linas Kudzma (baravykas)

Specimen available

Collected in predominantly Hemlock woods. Some spores are strongly dextrinoid in Melzer’s others are not. This variable and very strong dextrinoid reaction is not mentioned in any references I have. Spores are narrowly ovoid and the size is variable with a 20 spore average of 12.2 × 5.3 microns, Qm = 2.31. Careful selective focusing of the microscope reveals subtle irregular pitting of the spore surfaces.
