Tubeuf phot.) present a striking modification, the primary xylem alone is normal, the vessels of the secondary wood remaining rudimentary; other parts are not lignified, and the phloem is only indistinctly laid down. A mycelium is present in all deformed parts, but absent in normal green tissue. It becomes massed to form a hymenial layer beneath the epidermal cells or between their outer walls and the cuticle. The sterigmata do not exceed four in number, and.
