  We carried out a search for M-type Vega-like stars by correlating the IRAS
Faint Source Catalog with Hipparcos selected M-type stars. Three stars with
apparent IRAS 25mu excess emission are shown instead to be non-IR-excess stars
from ground-based 11.7 and 17.9mu photometry. Two stars previously suggested to
have Vega-like mid-IR excess are also shown to be non-excess stars. These
results imply that other suggested mid-IR excess stars in the literature may
also be false excess stars. Detection threshold bias is apparently responsible
for these bogus IR excesses. Sixty micron excess emission from a previously
known M-type Vega-like star (GJ 803) is identified again.
