uniformly distributed in this area, despite slight differences 
in the character of the several places visited. The woods in 
the neighbourhood of Hutton Beck yielded the more prolific 
gatherings, and what species were found there were duplicated 
in the Kirkdale area. The addition to the County records of 
three species may be considered very satisfactory. Lactarius 
violascens found in woods on the right hand bank of the River 
Dove is a very interesting addition to our Lactarii. The 
investigation also resulted in obtaining records for twelve 
other species new to the well-worked N.E. Division, V.C.62, 
threee of which are first records in the County.
