Diagnosis: Characterized by die large, brownish, strongly con-
vex, bullate galls up to 10 mm diam. on die diallus of Fla-
voparmelia caperata, the subspherical to ellipsoid, longitu-
dinally 1-septate basidia, with cells longer than the septum,
16-22 x 11-17.5 pm, and the large, subspherical to shortly
ellipsoid basidiospores 8.5ù11.5(ù13) x 7.5-11 pm.
Etymology: From Flavoparmelia, the host lichen.

Basidiomata absent; fungus inducing the formation of

Although the host Flavoparmelia caperata is particularly
common in Europe and other parts of the world, and the
galls induced by the fungus are large and eye-catching, it is
astonishing that the species in known only from the USA.
Tremella flavoparmeliae, USA, North Carolina, holotype. Basidio-
matal galls on the thallus of Flavoparmelia caperata. Scale bar: 1 mm.
lipsoid, with 1 longitudinal septum, individual cells often
longer than the septum, 16ù22 x 11ù17.5 pm; epibasidia
cylindrical, 20-40 pm long. Basidiospores subspherical
to shortly ellipsoid, 8.5-11.5(-13) * 7.5-11 pm. Asexual
stage: asteroconidia frequent, arms 4-7 pm; conidiogenous
cells 15-10 x 1-2.5 pm.
Ecology and host. On the thallus of Flavoparmelia caper-
ata, gall-inducing.
Distribution. North America (USA: Minnesota, North Car-
olina, Virginia).

Notes. The galls induced by this species strongly resemble
those of Tremella evemiae, a species confined to Evemia
mesomorpha. It differs from that species by the much larger
and constantly 1 -septate basidia (vs 2-4-celled basidia, 9-14
x 9-13 pm) with cells that become longer than the septum,
aid from many lichenicolous species by the large basidio-
spores.
