The Mould Fungi of New Zealand.
II.The Genus Aspergillus

[Read before the Manawatu Branch, September 21, 1938; received by the Editor, December 22, 1938; issued separately, September, 1939.]

Fungi belonging to the genus Aspergillus constitute, with the closely related genus Penicillium, the common spoilage moulds of foodstuffs, textiles and leather the world over. Several of them are pathogenic to plants and animals, including man. Others are used in industry—notably in the manufacture of citric acid and in the preparation of fermented food and drink. Of the multitude of articles published by botanists, pathologists, and chemists touching the Aspergilli, comparatively few deal with the botanical classification of the genus. The monograph by Thom and Church (The Aspergilli, 1926) is the only comprehensive work of this character published within recent years. In it the authors review the world's literature on the genus, supplemented by personal examination of a wide range of specimens and of type cultures. They define, in general terms, groups composed of related species, but rarely lay down definite lines of demarcation between the species comprising each group. While the inquirer can, with reasonable precision, place his specimen within a group he is left in some doubt as to the choice of a specific name.

In attempting to record the New Zealand Aspergilli it has been found necessary to lay down clear boundary lines between species, based on definite morphological characters. This has entailed a review of the systematics of the whole genus and the relegation to synonymy of all but 18 of the 66 specific names accepted by Thom and Church out of the 400 or so in existence.

The strains recorded here have been isolated in the course of industrial and soil mycological work over the past four years. They do not purport to form a complete list of the Aspergilli present in New Zealand.

Sterile hyphae creeping, septate, hyaline, sometimes in age tinged yellow or brown. Fertile hyphae (stalk) erect, normally unbranched, thick walled, budding from side-wall of a hyphal cell which often becomes thick walled, swollen and distorted (foot-cell), very sparsely septate, with apex swollen to form a globose, flask-shaped, or more or less clavate vesicle. Sterigmata arising as buds from the vesicle wall, either bearing conidia directly (1 series), or budding at apex 1 to 5 secondary sterigmata which bear the conidia (2 series). Conidial sterigmata cylindrical or vase-shaped, narrowing more or less abruptly at apex to form an apical tube within which the conidia arise in succession. Conidia continuous, elliptical or globose, hyaline or with outer wall coloured green, yellow, or brown, in unbranched chains

radiating so form a mop-like or globose head, or more or less compacted to form stellate masses or cylindrical columns, not enveloped in slime.

Perithecia, when present, globose or oval, cleistocarpic, thin-walled. Asci globose, containing 8 spores. Ascospores more or less lens-shaped, with or without median groove and projecting membranes.

Sclerotia, when present, more or less spherical, composed of compacted masses of globose cells with lumen nearly filled with horny material.

There appears to be no clear line of division between the genera Aspergillus and Penicillium. P. spinulosum might well pass for a small columnar Aspergillus, its numerous sterigmata being borne on an apical vesicle more than twice the diameter of the stalk. The swollen and contorted “foot cell” at the base of the stalk, though prominent in the larger forms, is less easily observed in degenerate cultures or in small stalked species such as A. fumigatus, nor is it present at the foot of stalks that arise from aerial hyphae. Certain Penicillia also exhibit definite footcells. Pure cultures of Aspergilli, when becoming degenerate through age, staling, unsuitable media, or bacterial contamination, often produce typically penicillate fructifications. The general morphology of the essential organs of propagation, sterigmata and conidia, varies more between the species of each genus than between the two genera as a whole.

However, the generally accepted conception of the two genera is sufficiently distinct to obviate the necessity for altering such well-established names.

Border-line species can well be placed in one or the other.

The Species Of Aspergillus

In attempting to key and define the species of the genus it is imperative that characters are used that are constant, within specified limits, under all conditions of growth, and that are precisely definable in words. To be of value such a key must allow a worker unfamiliar with the group to name a specimen in hand rapidly and with confidence, independent of the medium on which it occurs. It is, of course, not possible to lay down rigid boundary lines between such variable and closely related organisms, but the key characters should be so chosen that border-line strains may be placed with the least doubt. Defined thus the species name must inevitably cover a number of strains variable in other than the key characters.

Discussion Of Key Characters

Colour.

This is taken to apply to the conidial heads in mass. The exact shade is too variable a character for use in the separation of closely-related species, but, in the generalized form of blue-green, green, yellow-green, yellow-brown, flesh-colour, white or black, constitutes a convenient and immediately apparent character for separation of the species into major groups. It has been so used by most workers on the genus.

Morphology.

The organs available for morphological comparison are the vegetative mycelium, stalk, foot-cell, vesicle, sterigmata, conidia, sclerotia, and perithecia.

– 239 –

Vegetation mycelium. Careful observations have failed to find any constant distinguishing character in either the submerged or aerial mycelium of different species. The various coloured inclusions and accretions, and the swellings and abnormalities of the submerged hyphae, that are sometimes present, as well as the relative abundance of aerial hyphae, to some extent characteristic of certain strains and species, are, in general, variables associated with age and vigour.

Stalk. Measurements of length, diameter, and thickness of wall provide useful descriptive data, but are not suitable for use as key characters. Smoothness of outer wall as contrasted with walls bearing wart-like accretions, usually washed off in mounting, but leaving scars or pits, forms a readily observed and useful key character. Stalk colour is apparently a constant character for some species and for them constitutes a key character.

Foot-cell. Shape and dimensions of the foot-cell vary greatly between individual stalks in any one colony and therefore have no diagnostic value as between species.

Vesicle. The shape of the vesicle is of value in separating A. clavatus from other Aspergilli, but otherwise variations cannot be defined with sufficient precision. The manner in which the sterigmata are borne upon the vesicle is of indirect value in that it indicates whether the heads are normally columnar or radiate—a key character usually observed directly on the growing colony.

Sterigmata. Whether the sterigmata are unbranched (1 series) or branched (2 series) constitutes a key character that must be used with discretion. Age and conditions of culture may influence the branching of the sterigmata and some species may have both branched and unbranched sterigmata in the same colony. Other species, however, are constant in producing their sterigmata in either 1 or 2 series and with these the distinction is valid.

The relative morphology of the sterigmata is of some diagnostic value, but the distinctions are difficult to define succinctly.

Conidia. Conidial morphology has been used in the present key as a character for separation of certain species only. The conidia of some species vary in shape and size, and in markings of the epispore, between strain and strain and even under different conditions of culture. All three characters, however, are valuable confirmatory aids to diagnosis and are detailed in each species description. Colour in the mass and the manner in which the conidial chains are borne on the undisturbed head, whether radiate or compacted into solid columns, are characters of the utmost value for key divisions.

Sclerotia. Formation of “Hiille” cells * and of sclerotia, though apparently a property of certain species only, is governed largely by environmental conditions and therefore cannot be considered a key character.

[Footnote] * “Hülle cells” are special cells, usually terminal to aerial vegetative hyphae, in which the walls are so thickened as nearly to obliterate the lumen. They are particularly well observed in the hyphal weft surrounding the perithecia of A. nidulans.

– 240 –

Perithecia.

Perithecia are at present known for only a very few species of Aspergilli. Strictly such species should be classed under the ascomycetous genus Eurotium, but, in agreement with most workers, they are here retained under Aspergillus.

Cultural Characters.

These vary so widely between strain and strain, and under varying conditions, that they have little or no value for key purposes. As aids to diagnosis they have at times some value and as such are given for each species grown on a standardized medium, Czapek's solution agar ex Thom and Church:—NaNO 3 2 grms., K2HPO4 1 grm., MgSO4 0.5 grm., KCl 0.5 grm., FeSO4 trace, Sucrose 30 grms., water 1 litre, Agar 15 grms. The addition of 10 grms. of “Marmite” to the above formula greatly improves colony vigour without affecting other characters.

– 243 –

The “slime” condition described for “A. conicus” by Dale and by Thom and Church (The Asperg., p. 125, 1926) was present an the colony which developed on an air-exposed plate of “Difco” prune agar. Subcultures direct to Czapek and potato-dextrose agars were also slimy. A similar condition had been noted in old stock cultures of A. glaucus. No bacteria could be found in direct examination or in dilution cultures on various media, nor could the condition be produced in non-slimy colonies by direct inoculation. It was found, however, that transfers of mass inoculum to “Difco” prune agar plus 40% cane sugar produced colonies apparently healthy and free from slime.

The “slime” condition is associated with other evidences of degeneration—contorted hyphae, lack of vigour, irregularity in fruiting, darkening of colour in the submerged hyphae and in the media, etc. The conidia remain normal. The two strains isolated from oats did not show the “slime” condition. It appears therefore, that the condition is of physiological origin and is not a constant species character—an opinion also held by Blochwitz (Ann. Myc., vol. 23, p. 206, 1929).

Heads dark green, later dull green to grey-brown, radiate, irregular in outline, mop-like rather than spherical, 75—150 μ diam., 40–60 μ deep. Stalks smooth, hyaline or tinted yellowish-green in upper part, 0.5-3 mm. × 8–15 μ, walls 0.5-1 μ, thick. Vesicles globose to flask-shaped, 15–30 μ diam., fertile over upper three-quarters of surface. Sterigmata in 1 series, not crowded, 6–12 μ × 3.5-5 μ, vase-shaped, tapering only slightly to apex and closely resembling the first conidium. Conidia at first smooth, highly elliptical, later generally coarsely verrucose or wrinkled, occasionally remaining smooth, elliptical, pyriform, or almost globose, very variable, 4–12 μ × 4–8 μ, in separate, loose, radiate chains. Perithecia bright yellow, darkening somewhat in age, subglobose, 75–120 μ diameter, not enclosed in hyphal weft. Asci globose, about 11 μ. diameter. Ascospores lens-shaped, circular in plan, 4.5-5.5 μ diameter, elliptical in elevation, 3.5-4.5 μ. deep, with median groove either bounded by projecting membranes 0.5-1 μ wide, or without membranes, or again showing clear elliptical outline with no sign of groove, or at most a slight flattening of the ends.

Czapek colony restricted, more or less floccose, varying in appearance with the strain and conditions of culture, some becoming quickly ascosporic with suppression of conidial formation and consequent predominance of yellow colouration, others spreading widely, with little or no formation of perithecia, appearing dark green, browning with age, or tinged in zones dark yellow or rust colour due to coloured inclusions within, or accretions upon the vegetative hyphae. Reverse various shades of greenish-yellow to rusty-brown. Some staining the media, others not.

Habitat: Silk and cotton fabrics, diseased bee-larvae, tobacco, dried fruit, soil, dead plant parts in glasshouse, sawn timber, jams and preserves, hessian meat wraps, grass seed, air-exposed plates in milking sheds, dairy factories, workrooms and hospital wards, cheddar cheese, leather, sheep-skins, beef dripping, rolled oats and oatmeal, mouldy wheat, barley, peas and bread. (49 isolants.)

The writer has followed Wehmer and Lindau in adopting the specific name glaucus Link as covering the range of forms, here listed as synonyms, included in the “A. glaucus” group of Thorn and Church. Divisions in general rest upon the relative morphology of the ascospores and show a graduated range making the delimitation of any particular form very difficult. Smith (1931), discussing the 42 strains of the “A. glaucus” group examined by him, divides these into 4 species, A. repens, A. ruber, A. amstelodami and A. chevalieri, mainly on ascosporic, secondarily on cultural characters. Among the 49 strains collected in New Zealand, though the majority agree with his delimitation of A. repens, there is a range of ascosporic character covering all four “species,” but the writer has not been able to correlate them with the associated secondary cultural characters of Smith. Failing a clear line of demarcation in the conidial stage, differences in the ascosporic stage should not be used to separate species of the “imperfect” genus Aspergillus however valid they may be in the classification of the “perfect” genus Eurotium.

Czapek colony usually very vigorous, spreading, more or less floccose, at first white, soon becoming covered with concentric rings of dark-brown, black, or dark purple fruiting heads which finally coalesce into an almost solid crust, aerial hyphae often tinged canary-yellow. Reverse colourless to bright yellow, greenish-yellow or brown.

Habitat: Annatto seed, tent calico, bulbs, germinating seeds, soils, pelts, stored onions, macaroni, rolled oats, oatmeal, malt, wheat-meal, rice, exposed plates in library, workrooms, clothing stores, and hospital. (23 isolants.)

A. nanus Mont., A. luchuensis Inui, A. perniciosus Inui and A. japonicus Saito have here been listed as synonyms of A. niger van. Tieg., since, in agreement with Thorn and Church (The Asperg., p. 171, 1920), the writer does not consider the absence of secondary sterigmata alone as a sufficiently constant character to warrant separation. Several New Zealand strains of A. niger show heads with either 1 or 2 series of sterigmata in the same culture, and one strain, otherwise indistinguishable from type, has sterigmata persistently in a single series. To quote Thorn and Church (l.c.) “we appear to be dealing with a cosmopolitan, almost omnivorous group of races or species which show great variability with probably many natural or induced variations.”

S. sulphurea Fresenius, Beitr. Z. Mykol., vol. 3, p. 83, 1886.

This species is known only from the imperfect description of Fresenius, and from dried herbarium material, in the interpretation of which Wehmer, Thom and Church and Blochwitz differ.

Thorn and Church would apply the name to strains of A. ochraceus producing bright yellow heads and not producing sclerotia.

The name should be dropped.
