Bactrodesmium sp.: Comprise a very small proportion
of the fungal biota. Rarely found but may be identified
on surfaces by tape lifts, tease mounts from bulk
samples, and in air by spore trap samples. (Spores
have distinctive morphology) Natural habitat includes
wood and bark of various deciduous trees such
as oak, ash and sycamore.
Basidiomycetes: Fungal spores which are from
mushrooms. The specific mushroom species cannot
be identified on the culture plate. Many mushroom
spores are reported to be allergenic.
Basidiospores: Spore formed on a structure known
as a basidium. Characteristic of the Basidiomycete
class. Example: Rusts, smuts, and mushrooms.
Beauveria sp.: Contaminant. Known to be pathogenic
in animals and insects. Rarely involved in human
infection.
Beltrania sp.: Comprise a very small proportion
of the fungal biota. May be identified in air
by spore trap samples. (Spores have distinctive
morphology) Beltrania needs specialized media
for sporulation in the laboratory. Natural habitat
includes dead leaves and plant litter of semi-tropical
and tropical plants.
Bipolaris sp.: A fungus with large spores, which
would be expected to be deposited in the upper
respiratory tract. This fungus can produce the
mycotoxin sterimatocystin, which has been shown
to produce liver, and kidney damage when ingested
by laboratory animals.

Blastobotrys sp.: Rarely found but may be identified
on surfaces by tape lifts, tease mounts from bulk
samples, and in air by culturable (Anderson) samples.
(Spores do not have distinctive morphology and
would be characterized as “other colorless”
on spore trap samples.) Recorded isolations include
seeds and compost.
Blastomyces sp.: Human pathogen. The fungus is
commonly found in soil. It is a dimorphic fungus,
which has filamentous fungus when grown at 25
degrees C and a yeast form at 37 degrees C.
Botrydiplodia Theobromae: (see Lasiodiplodia)
Botrymyces sp.: This genus is not treated by
many reference books on fungi. Described by the
mycologist de Hoog, the multi-celled irregularly
septate, thick-walled “spores” may be
regarded by some to be vegetative structures.
Some laboratories see this organism on wood.
Botrytis sp.: Contaminant. Reported to be allergenic.
It is parasitic on plants and soft fruits. Found
in soil and vegetables. Possibly associated with
allergic symptoms.
