Abstract:
The usual host of this new parasite, Helicosporidium parasiticum, is the larva of a Ceratopogonid, Dasyhelea obscura Winnertz, which lives in the decomposed sap filling the wounds of treeselm and horse-chestnut. All the material used for this study was derived from the wounds of two trees only: (1) an elm tree standing on the Caius College ground at Newnham, facing Church Rate Walk, and (2) a horse-chestnut standing between the School of Agriculture and Downing College.
