medium, obverse 75
2.45 Scopulariopsis sp. after 14 days, 9 cm dish, MEA
medium, reverse 75
2.46 Scopulariopsis sp. looks similar to P enicillium sp. but
the overall look of the colonies is powdery with no true
green shades, varying from white to buff, brown and
black 76
2.47 Growth after 14 days, 9 cm dish, MEA medium,
obverse. Four colonies of hyphaceous fungi, one
colony of bacteria or some yeast 76
2.48 The dark reverse of the middle colony suggests
Cladosporium sp. Growth after 14 days, 9 cm dish,
MEA medium, reverse 77
2.49 With no other information regarding the large white
colony, only microscopic analysis of the fungus could
give the answer 77

2.50 Probably Penicillium sp. and Aspergillus sp. of
Aspergillus niger group. Growth after 14 days, 9 cm
dish, MEA medium, obverse 78

2.52 Presence of Penicillium sp. was confi rmed, showing a
typical view of the conidial head of A spergillus sp. 80
2.53 Alternaria sp. is one of the fundamental genera for the
normal and average mycofl ora of the air. Growth after
14 days, 9 cm dish, Czapek medium, obverse 81
2.54 The hyphae of Alternaria sp. are not hyaline, but show
different shades of brown. Growth after 14 days, 9 cm
dish, Czapek medium, reverse 81
2.55 Alternaria sp. spores are septated, made of a few
elements, like bricks 82

14 days, 9 cm dish, MEA medium, obverse 82
2.57 The dark reverse of the colony. Growth after 14 days,
9 cm dish, MEA medium, reverse 83
2.58 In microscopic observation, Cladosporium sp. may be
problematic 83
2.59 Typical air sample dish with different Penicillium sp.
colonies. Growth after 14 days, 9 cm dish, MEA
medium, obverse 84
2.60 The hypothesis of Cladosporium sp. so far not
disproved, the dark reverse. Growth after 14 days, 9 cm
dish, MEA medium, obverse 84
2.61 Microscopic observation confi rmed the hypothesis of
Cladosporium sp. 85
2.62 Moderately clean air sample. Growth after 14 days,
9 cm dish, MEA medium, obverse. 85
2.63 Two colonies have dark reverse, a good step towards
identifi cation of Cladosporium sp.. Growth after
14 days, 9 cm dish, MEA medium, reverse 86
2.64 Cladosporium sp., identifi ed on the basis of microscopic
observation 86

Trichothecium sp. this time. Growth after 14 days, 9 cm
dish, MEA medium, obverse, white background 88
2.68 The same dish photographed upon the black
background for better demonstration of the
Trichothecium sp. structure. Growth after 14 days, 9 cm
dish, MEA medium, obverse, black background 88
2.69 Trichothecium sp. and two other colonies with dark
reverse. Growth after 14 days, 9 cm dish, MEA medium,
reverse, white background 89
2.70 Trichothecium sp. and two other colonies with dark
reverse. Growth after 14 days, 9 cm dish, MEA medium,
reverse, dark background 89
2.71 Characteristic microscopic view of T richothecium sp.
and its conidiophores, like dull- spiked clubs with short
handles 90
2.72 Perfect development of a single P enicillium sp. colony.
Growth after 14 days, 9 cm dish, MEA medium, obverse 90
2.73 Characteristic zonation is visible on reverse even.
Growth after 14 days, 9 cm dish, MEA medium, reverse 91
2.74 Characteristic microscopic look of P enicillium sp. 91
2.75 Mostly different Penicillium sp. colonies but also 3
Cladosporium sp. Growth after 14 days, 9 cm dish,
MEA medium, obverse 92
2.76 Different Penicillium sp. colonies and 3 C ladosporium
sp. Growth after 14 days, 9 cm dish, MEA medium,
reverse 92
2.77 Different Penicillium sp. colonies and 1 C ladosporium
sp. Growth after 14 days, 9 cm dish, MEA medium,
obverse 93
2.78 Different P enicillium sp. colonies and 1 Cladosporium sp.
Growth after 14 days, 9 cm dish, MEA medium, obverse 93
2.79 There are few colonies of probably 1 Penicillium sp.,
but also probably 1 Cladosporium sp. Growth after
14 days, 9 cm dish, MEA medium, obverse 94
2.80 Since all the colonies of P enicillium sp. seem to be of the
same age and of the same species, why did the one
‘capturing’ the C ladosporium sp. grow almost twice as

Cladosporium sp.? Growth after 14 days, 9 cm dish,
