Baden-Württemberg - Lichens of Wales

thickening from the remaining cells; site of
nitrogen fixation.
hymenial algae: algae which are in the interior of
the hymenium of perithecia and become ejected
with the spores, smaller than the remaining algae.
hymenial gelatin: gelatin-like filling material in
the hymenium, cementing paraphyses etc.
hymenium: layer of paraphyses and asci in the
fruiting body of lichens (fungi).
hyphae: filamentous organs, of which fungus or
for the most part even the lichens are
constructed, producing dense tissues in lichen
thallus or in the fungus fruiting body.
hypothallus: spongy tissue of the underside of
many foliose lichens.
hypothecium: region within the hymenium.
inspersed: (hymenium) having fine oil droplets.
involucrellum: the receptacle partially or
completely surrounding a perithecium, often a
dark colored envelop or ± covering layer of the
apex of the perithecium.
isidium: warty, peg-form, coralloid branching or
± spherical outgrowths of the thallus upper
surface, used for vegetative reproduction.
isidiate: with isidia.
isotomic: in the case of branching; the branching
equally strong and growing uniformly.
core: interior of a perithecium.
conidia: asexual reproductive body, e.g.
produced in the pycnidia.
capitate soralia: spherical soralia on the ends of
the lobes.
coraloid: coral-like, i.e. of cylindric branching
segments.
crustose lichen: lichens one with the substrate
lying closely bound crust-like, coherent, areolate
or ± squamulose thallus, not or scarcely able to
loosen without destroying.
cryptolecanorine: apothecia sunken into the
thallus, bordered by the thallus, but without a
thalloid margin (set off).
spherical soralia: (capitate or laminal): ±
spherical soralia on the upper surface of the
thallus.
Kurzzweig: short unbranched side branches.
thalloid margin (thalline exciple): produced by
the thallus and commonly ± thallus colored algae
containing border of an apothecium.
Laubflechte : foliose lichen.
lecanorine: apothecium with thalloid margin.
lecideine: apothecium with black proper margin.
leprose: thallus completely erupted dusty,
without cortex.
lichenized: producing a lichen, i.e. the fungus is
associated with algae, or algae with a fungus.
lip soralia (labriform) lip-form curved soralia on
the underside of the lobe end.
lirellae: long narrow apothecia.
macroconidia: in the case of species with at least
two conidia forms (pycnospore forms) the larger
conidia type.
collar soralia: in the case of soralia, the ring
form produced around a hole.
medulla: loose hyphal tissue underneath the algal
layer.
muriform: cross and longitudinally divided spore;
weakly muriform: with less cells.
mazaedium: dusty mass of spores and remains of
asci and sometimes also paraphyses, covering the
fruiting body.
mesoconidia: in the case of species with at least
three conidia forms (pycnospore forms) the
middle sized conidia type.
micareoid: algae small (4-7 µm), thin-walled,
often in pairs (in the case of Micarea).
microconidia: in the case of species with at least
two conidia forms (pycnospore forms) the
smaller conidia type.
modification: environmental influenced, non
hereditary change.
navel (umbilicus): ± central, often single
attachment of a foliose lichen, also a pointed
nipple-like outgrowth of the disk of an
apothecium.
navel lichen (umbilicate lichen): foliose lichen
attached with a navel.
needle-form (acicular): in the case of spores:
long, narrow, long pointed on one end.
net-ribbed (reticulately ridged): upper surface
divided by weakly raised ridges surrounding
weakly concave regions.
ocular chamber: short finger-like projections of
the ascus interior region into the (inner) wall of
the ascus tip.
ostiole: pore-form opening at the apex of the
perithecium.
palisade parenchyma: tissue, whose hyphae are
oriented ± at right angles to the upper surface.
papillae: small, usually ± regularly round,
convex outgrowths of the thallus, not sharply
separated from isidia.
parallel multicellular (septate): spores in the
case of 3 or more ordered one behind the other.
paraphyses: filamentous, branched or
unbranched, usually vertical ordered hyphae in
the hymenium, attached at the base.
