E
Echinulate
Covered with delicate spines
Endospore
A spore formed within a spherule by a cleavage process following karyogamy and mitosis.
Exudate
Droplets of fluid formed on the surface of a colony.
Glossary 129
F
Favic chandelier
A repeatedly branched cluster of hyphal apices that resembles a chandelier.
Fission
A discrete cell is divided with one or more septa, each segment becoming liberated as a separate cell.
Fission arthroconidium
An arthroconidium that is released by fission through a double septum, eg: in Geotrichum.
Flexuose
With smooth bends
Floccose
Having a cottony texture.
Foot cell
The base of a macrophialoconidium produced by a species of Fusarium having a heel-like projection; the base of the conidiophore of Aspergillus species where it merges with the hypha and resembles the heel and toes of a foot.

Fragmentation
Separation of a hyphae into conidia.
Fungus (pl. fungi)
A eukaryotic, unicellular to filamentous, achlorophyllous organism having an absorptive nutrition. A fungus reproduces by sexual, asexual, or both means.
Funiculose
Aggregated into ropelike strands.
Fusiform
Spindle-shaped, swollen near the middle, strongly narrowed towards both ends.
Glossary 131
G
Geniculate
With repeated knee-like bents.
Germ pore
Circular thin-walled part of a propagule through which germination takes place.
Germ tube
A hypha initially developing from a conidium or spore.
Glabrous
Smooth; (of colony), without aerial mycelium

Hemispheric
Half of a sphere.
Hilum
Slightly prominent basal scar.
Homothallic
A fungus capable of sexual reproduction on a single thallus.
Hulle cells
Thick walled cells with characteristic thin walled pores,usually associated with cleistothecia of some species of Aspergillus.

Hypha
An individual filament of a fungus.
Glossary 133
I
Intercalary
Incorporated in a mycelial filament, in between hyphal cells.
Internode
That portion of a hypha that is between two nodes.
K
Karyogamy
Fusion of two nuclei during a sexual process.

The smaller of two conidia of two different sizes that are produced in the same manner by a single fungus.
Moniliform
Coherent chain of cells.
Mould
A filamentous fungus.
Multiple budding
Blastoconidia developing at different sites on the surface of a parent cell
Muriform
Having vertical and horizontal septa.
Mycelium
