WASHINGTON (AP) _ A special report on the plight of the hungry and homeless in Dallas earned a five-member team from the Dallas Morning News the 1986 Heywood Broun Award.

Three of the five winners accepted the $1,000 Newspaper Guild award at a Tuesday luncheon at the National Press Club, said Guild spokesman Philip M. Kadis.

Four reporters and a photographer spent two months living on the streets of Dallas, eating in soup kitchens and sleeping in shelters before producing a 16-page Thanksgiving Day report.

The team included reporters David Tarrant, Melinda Henneberger, Leslie Pound and Dan Barreiro and photographer David Leeson. All but Ms. Henneberger and Barreiro, who has left the Dallas paper and now works as a columnist for the Minneapolis Star and Tribune, attended the luncheon, Kadis said.

The five ''put faces on the anonymous and revealed an unhidden but invisible world,'' said the Broun award judges, who noted that the report brought a deluge of contributions for the homeless.

The judges for the 46th annual award were James Polk, an NBC News investigative reporter; Juliet O'Neill, senior correspondent in the Canadian Press Washington bureau; and Ray Jenkins, editor of the Baltimore Evening Sun's editorial page.

Broun, whose concern for the underdog and the underprivileged was reflected in newspaper columns published in the 1920s and 1930s, was the Guild's founding president. The award is given for outstanding individual journalistic achievement in Broun's spirit.

Two other Dallas Morning News reporters, Steve McGonigle and Ed Timms, won honorable mention for reporting that disclosed the systematic exclusion of blacks from juries in Texas.

Honorable mention also went to reporters Mike Kelly and Mary Kane and photographer Mel Grier for a series in the Cincinnati Post on the plight of 74,000 slum residents, a effort that resulted in changes in housing-code enforcement.
