Neosartorya sp.: Sexual state of Aspergillus
species, notably the aspergillus fumigatus group
among others. Neosartorya is common and is most
closely related to Emercilla, another genus with
Aspergillus anamorphs. Neosartorya is likely to
be present along with related aspergilli if growth
has been long term and the nutrients of the substrate
are conducive for the conversion to sexual phase.
Reports of illness include pulmonary infection,
encdocarditis, and osteomylelitis. Health effects
(for the most part), allergenicity, and toxicity
of Neosartorya are closely related to the aspergillus
anamorph and have rarely been studied apart from
that primary phase. May be identified on surfaces
by tape lifts, and tease mounts from bulk samples,
especially if the Aspergillus anamorph is present.
If Neosartorya spores are isolated on culturable
sampling, the Aspergillus anamorph is likely to
be the identifiable result, at least with primary
growth within one week. Spores have somewhat distinctive
morphology but would most probably be called “ascospores”
on spore trap samples. Natural habitat is soil.
Nigrospora sp.: Found in decaying plant material
and soil. Mode of dissemination: Active discharge
mechanism. Does not require wind or rain. Type
I allergies (hay fever, asthma) Very rare report
of human infection. Rarely found growing indoors,
Characteristics of growth/culture: White, flucose,
spreading. Develops black spore clusters with
time. A distinctive large, dark brown (nearly
black ), globose spore is readily identifiable
on spore trap slides. Distinctive but rarely found
on tape lifts.
Nodulisporium sp.: Comprise a small proportion
of the fungal biota. This genus is most closely
related to Geniculosporium, Hansfordia, and Calcarisporium.
No information is available regarding health effects,
or toxicity, Allergenicity had not been studied.
May be identified on surfaces by tape lifts, tease
mounts from bulk samples, and in air by culturable
sampling. Spores do not have distinctive morphology
and would be categorized as “other colorless”
on spore trap samples. Natural habitat includes
soil and dead stems of trees and herbaceous plants,
especially dead wood in the tropics.
Non-Sporulating sp.: These are organisms that
have not sporulated under the culture conditions
provided. Most never sporulate in culture (sterile
mycelia). Some represent non-sporulating colonies
of common fungi (e.g. Clidiosporium, Alternaria,
even Aspergillus). Grows on a variety of substrates.
Identification is not possible without sporulation.
Potentially all fungi are capable of producing
a non-sporulating state. Many fungi so not adapt
well to routine mycologic media and growth conditions
and therefore may not sporulate. Specialized media,
light-dark cycles, UV light, and low or high temperatures
ma be required to stimulate sporulation. Unless
distinctive spore types are formed, identification
may not be possible. Frequently non-sporulating
colonies are produced by basidiomycetes (mushrooms),
which usually do not produce fruiting structures
on lab media. They may produce clamp connections
and/or arthroconidia within their mycelia. Hyphal
fragments are not routinely counted or reported.
If numbers are excessive a comment indicating
high numbers of hyphal will appear on the report.
Non-sporulating mycelia may appear as colorless
or pigmented (brown), septate (with cross-walls)
or non-septate. Further identification requires
sporulation on tape lifts.
