The ITS regions of 14 isolates of endophytic fungi obtained from the root s
ystems of four Woollsia pungens plants were sequenced and compared to seque
nces of Hymenoscyphus ericae, Oidiodendron maius and to sequences from othe
r fungal taxa currently available in the GenBank and EMBL nucleotide databa
ses. Sequence data suggested that six distinct Laxa were present in the roo
t systems of the four plants and that up to four of these were present in t
he root system of a single plant. One of the endophytes was identified as a
n Oidiodendron species, while most other isolates probably belong to the Le
otiales.
