摘要:

SummaryDasyscypha Agassizii(Berk.&Curt.) Sacc. was found to be very abundant upon plantedPinus Strobus, especially on blister rust cankers, and to occur also on several pine lots studied.This fungus has been known in literature only uponAbies balsamea. This host is found to be the usual one for the fungus, but collections are here noted also uponTsuga canadensis, Pinus monticola, Picea rubra, Picea mariana, and possiblyPseudotsuga taxifoliaas well asPinus Strobus.The habitat ofDasyscypha Agassiziiis apparently sub-boreal. The herbarium specimens available were from north of 43°30' north latitude for the most part (excluding two doubtful forms), the exceptions being from Pennsylvania at 1,000 feet, and from Massachusetts and southern New Hampshire.The ascospores of material upon white pine and spruce were found to be somewhat more slender than given by Saccardo.A description of the mycelium in blister rust cankered white pine bark is given.
