There are 44 agaric genera reported from Australia that are excluded from FunKey because the records are (1) erroneous, (2) lack supporting evidence or (3) lack full documentation that would allow coding of their characters. For most of these genera, there is one or a few species suggested as occurring in Australia, and the species are usually rare or geographically restricted. Many of the excluded genera have been recorded from Australia on the basis of the occurrence of species described originally from the Northern Hemisphere. Many such records were first made in the 19th century, all published or compiled by Cooke (1892), and the species have not been recorded subsequently. Nineteenth century records of species originally described from the Northern Hemisphere have not been accepted unless authentic material has been examined recently to confirm diagnostic microscopic characters.

Some of the genera not yet included in FunKey are reported in recent literature (e.g. Grgurinovic, 1997a; Rees et al., 2003; Fuhrer, 2005; Ratkowsky & Gates, 2002, 2005; and lists in various issues of the Sydney Fungal Studies Newsletter) or there are recently determined herbarium collections in BRI, MEL or PERTH. These genera await further supporting documentation of their presence in Australia, both to confirm the record and to allow coding of characters for FunKey. In some cases older records have been discounted, as discussed below. The relevant genera are Callistosporium, Calocybe, Cantharellula, Clitocybula, Crucispora, Cystolepiota, Dermoloma, Flammulaster, Gerronema, Gomphus, Hemimycena, Hydropus, Kuehneromyces, Naucoria, Phaeomarasmius, Pseudobaeospora, Ripartites and Trogia.

Chamaeota is characterised by the pinkish spore print, the presence of an annulus and an inverse lamellar trama. It is similar to Volvariella (but this lacks a volva) and Pluteus (which has an annulus). Pegler (1965) transferred Agaricus insignis Cooke & Massee (type from Victoria) to Chamaeota, and this is the only report of the genus from Australia. Pegler (1965) found that the type lacked clamp connections and had smooth, 'orange-pink' spores. Illustrations with the type collection at K (T.W. May, unpubl.) show that the species more likely belongs in Agaricus, and the lack of clamp connections is consistent with that placement, although the spore colour as reported by Pegler (1965) would be anomalous. Further examination of the type specimen is required, especially the lamellar trama. Recent molecular studies show that at least some species of Chamaeota actually belong in Pluteus, which needs to be expanded to accommodate annulate taxa (Minnis et al., 2006)

The genus is reported from Australia on the basis of a record of C. lacerata (Gillet) Métrod by Cooke (1892: as Agaricus). Confirmation of this report requires a re-examination of authentic material. See also Recent reports yet to be verified.

In the scheme of Singer (1986) Collybia was recognised with nine sections, including Collybia, Iocephalae, Levipedes, Striipedes, Subfumosae and Vestipedes. The genus Collybia is now restricted to section Collybia (with type C. tuberosa (Bull.) P.Kumm. and a few other species); with a white spore print, the pileipellis a cutis, and often growing on other fungi and producing sclerotia (Antonín & Noordeloos, 1997). Microcollybia is a later synonym of Collybia in this narrow sense. Collybia racemosa (Bull.) P.Kumm., which was placed alongside C. tuberosa and allied species by Antonín & Noordeloos (1997), has recently been segregated in the genus Dendrocollybia, which has the stipe covered in short outgrowths terminating in tiny sterile pilei (Hughes et al., 2001). Collybia in the narrow sense does not occur in Australia, nor does Dendrocollybia. Australian species placed in Collybia in recent treatments now belong in either Rhodocollybia (for species placed by Singer in stirpes Maculata and Butyracea of section Striipedes) and Gymnopus (for species placed by Singer in stirpes Fusipes of section Striipedes, and in sections Iocephalae, Levipedes, Subfumosae and Vestipedes). Molecular data place D. racemosa and Collybia in the narrow sense in quite different clades, both distant from species of Rhodocollybia and Gymnopus (Moncalvo et al., 2002). Many Australian species of 'Collybia' still need assessment as to their correct genus.

An unidentified species of Crucispora is listed by Aberdeen et al. (1989), with no supporting details. Recently, McMullan-Fisher (2010) has reported the genus from Queensland (as Crucispora sp. 'rainforest'); with illustrations showing a fungus rather similar to Psathyrella in macroscopic appearance, but with distinctly cruciform spores. The record of this genus requires further investigation.

Cystodermella was errected by Harmaja (2002) for species formerly placed in Cystoderma section Granulosae, which differred from the type section of Cystoderma by the non-amyloid spores, higher ploidy level and lack of a strong association with bryophytes. The only species reported from the region is Cystodermella granulosa (Batsch : Fr.) Harmaja, but records of this species from Australia are doubtful.

The lamellate Daedalea quercina (L.) Pers. was recorded from Australia by Cunningham (1965). Other records of D. quercina compiled by May et al. (2003) are all as the anamorphs Xylostroma giganteum Tode or X. corium Pers. These two names have been widely misapplied in Australian literature to the sterile, leathery sheets formed in decaying wood by Laetiporus portentosus (Berk.) Rajchenb. The single collection of D. quercina cited by Cunningham (1965) on oak was made in South Australia in 1914. There is no reason to doubt the South Australian record, which should be regarded as an introduction of an exotic species, but the genus is omitted from FunKey pending confirmation that D. quercina has become established in Australia.

The genus contains some lamellate species. Daedaleopsis confragosa (Bolton) J.Schröt., which has elongate pores, was recorded from Australia by Cunningham (1965: as Daedalea) on the basis of a single specimen from Queensland, and in the same publication the species was also reported from New Zealand. Reid (1967) considered that Cunningham's use of the name was based on a misidentification, and Buchanan & Ryvarden (2000) also regard the New Zealand records as doubtful. The genus is not accepted as occurring in Australia.

Delicatula differs from Mycena in the inamyloid spores and hyphae and presence of a veil when young (Singer, 1986). Delicatula integrella (Pers.) Pat. was reported by Cooke (1892: as Agaricus). Confirmation of this report requires a re-examination of authentic material.

There are old records of this genus, as D. cuneifolium (Fr.) Bon, by Cooke (1892: as Agaricus) and Mathieson (1946: as Tricholoma). Confirmation of these reports requires a re-examination of authentic material. See also Recent reports yet to be verified.

Flammulaster was placed under Phaeomarasmius by Singer (1986), as subgenus Carpophilus, but accepted at generic rank by Horak (1980) and Moser (1983). Flammulaster siparia (Fr.) Watling is the only species of Flammulaster reported from Australia. Early records (Cooke, 1892: as Agaricus) must be regarded as dubious. The record by Willis (1963: as Flocculina) was accompanied by some data on macroscopic appearance, describing a small agaric growing on dead wood and litter with densely fibrillose pileus and russet lamellae. These details are insufficient to confirm its identity and, in the absence of information on microcharacters (and there being no collection under this name in MEL, which is where Willis material is held), the presence of F. siparia in Australia requires confirmation. See also Recent reports yet to be verified.

The genus was accepted by Moser (1983) and Singer (1986), differing from Conocybe in the plicate pileus and non-capitate cheilocystidia. The report of Galerella concocephala (Bull.) Bon from Australia (Cooke, 1892: as Agaricus) requires confirmation following re-examination of authentic material.

One species, G. carbonarium (Alb. & Schwein.) Pat., was reported from Australia by Cooke (1892: as Cantharellus leucophaeus (Pers.) Nouel-Malingié). Confirmation of this report requires a re-examination of authentic material.

Singer (1986) differentiated Gerronema from Omphalina by its pigmentation, when present, being intracellular and not dark-coloured. He included in Gerronema several sections, many species of which are now placed elsewhere, including lichenised species currently segregated as Lichenomphalia and various species subsequently transferred to Chrysomphalina Haas ex Cleménçon, Haasiella Kotl. & Pouzar, Loreleia or Rickenella. According to Singer (1986), species in subgenus Gerronema are lignicolous. Redhead (1986) restricted Gerronema to species with sarcodimitic tissue, although the placement of many of the species included by Singer (1986) has not been re-assessed in the light of this altered circumscription. The two species of Gerronema included in the molecular study of Redhead et al. (2002b) form a clade distant from other omphalinoid genera (Arrhenia, Omphalina sens. str., Lichenomphalia, Loreleia and Rickenella). However, the type of Gerronema is yet to be sequenced. Of the two species of Gerronema reported from Australia (May & Wood, 1997), records of G. holochlorum (Berk. & Broome) Pegler date from the 19th century (Cooke, 1892: as Agaricus) and require confirmation, and G. postii (Fr.) Singer is now placed in the genus Loreleia. In addition, Eyssartier & Buyck (2001) suggested that Cantharellus granulosus (type from South Australia) belongs in Gerronema, but they did not make a formal transfer. The species would be unusual in Gerronema due to the hymeniform pileipellis. Therefore the genus Gerronema is not included in FunKey. See also Recent reports yet to be verified.

Characterised by decurrent lamellae with black spore print, and reliably reported from New Zealand under exotic pines (McNabb, 1970), Gomphidius was included in a key to the genera of larger fungi occurring in the Australian Capital Territory (Shepherd, 1965), but as 'occurrence unverified' and no herbarium material has been seen from Australia.

Hemimycena has small fruit-bodies that are mycenoid or omphalinoid, but differs from Mycena by the inamyloid spores and hyphae and from Lichenomphalia by the presence of cheilocystidia and often also pleurocystidia. The pileipellis is a cutis or trichoderm, often with nodulose or diverticulate hyphae, rather than the hymeniderm characteristic of Marasmius. Hilton (1988) reported H. crispula (Quél.) Singer (as Delicatula) from Western Australia, and this is the only record of the genus from Australia. Hilton (1988) cited a herbarium specimen but provided no other details to support the record. Given that Grgurinovic (2003) in her extensive studies on Australian Mycena has not referred to confirmed records of any species of Hemimycena, the report of this genus from Australia is regarded as needing further documentation before it can be accepted. See also Recent reports yet to be verified.

NOTE ADDED IN PROOF: Lepp (2004) reported Hemimycena tortuosa from the Australian Capital Territory and Bougher (2010) reported H. cepalotricha from Western Australia. The genus Hemimycena will be added to the next edition of FunKey.

Hydropus differs from Mycena by the pileipellis which is either composed of smooth, filamentous hyphae or has pileocystidia, and in addition the hyphae are only rarely dextrinoid, and many species do not have amyloid spores (Singer, 1986). Hydropus putredinus (Berk. & M.A.Curtis) Pegler was reported from Australia by Cooke (1892: as Marasmius). Confirmation of this record requires a re-examination of authentic material. Hydropus anthidepas (Berk. & Broome) Singer is known from the Australian external territory of Christmas Island, but not from the geographic area covered by FunKey. See also Recent reports yet to be verified.

Hypsizygus ulmarius (Bull.) Redhead was included by Walters (1962: as Pleurotus ulmarius (Bull.) P.Kumm.), but without further details, in a list of species held in the Herbarium, Wood Preservation Section, Division of Forest Products, CSIRO. There are two collections filed under P. ulmarius at MEL (where the DFP Herbarium now resides). One collection (DFP 6465) has the characteristic echinulate spores of Conchomyces bursiformis (Berk.) E.Horak, agreeing with the description provided by Horak (1981). The other collection (DFP 6437) is sterile, but is also likely to be C. bursiformis, because of the presence of large, broadly clavate cheilocystidia and pleurocystidia with brown contents (as are present in DFP 6437). Therefore, H. ulmarius and the genus Hypsizygus should be deleted from the list of Australian fungi.

This is close to Pholiota but is distinguished by the non-viscid, strongly hygrophanous and translucent-striate pileus in combination with spores with a germ pore and the absence of chrysocystidia (Singer, 1986). Only Kuehneromyces mutabilis (Schaeff.) Singer & A.H.Sm. has been reported from Australia. Nineteenth century records (Cooke, 1892: as Agaricus) are doubtful. Dennis (1955) reported the species from Queensland, 'on rotting logs', but with no other supporting data. Presence of the genus in Australia requires confirmation. See also Recent reports yet to be verified.

Singer (1986) suggested that Agaricus luteoaurantius Kalchbr. (type from New South Wales) belonged in Lactocollybia, but he did not formally transfer the species to that genus. Pegler (1965) had placed it in Pleurotus, after examining the type and finding plentiful cheilocystidia and pleurocystidia with yellow contents, and similar structures on the pileipellis, although he could not locate spores. The generic position of Agaricus luteoaurantius remains unresolved.

Megacollybia platyphylla (Pers.) Kotl. & Pouzar was recorded from Tasmania by Eygelsheim (1981: as Collybia). There is no voucher collection and the brief description provided is not sufficient to confirm identification and therefore M. platyphylla and the genus Megacollybia should be deleted from the list of Australian fungi.

Thisw genus was originally described for Metraria insignis Sacc., a species with a volva and annulus and a pink spore print (Cooke, 1891). Type material at K consists of a painting and a spore print. The painting appears to be of a species of Amanita similar to A. rosea D.A.Reid (Reid, 1980), while spores from the spore print possibly match those of Hebeloma victoriense Holland & Pegler (Holland & Pegler, 1983). A lectotype specimen has not been selected. Depending on the choice of material (the spore print or the illustration) the genus will be a synonym of Amanita or Hebeloma.

Several species originally described in this genus from Australia by Cleland are referrable to other genera (Grgurinovic, 1997a). The one other species based on Australian type material, N. russa (Cooke & Massee) Sacc., is of uncertain generic position because the type has not been examined in the light of modern taxonomic criteria. A further seven species originally described from the Northern Hemisphere which are currently accepted in the genus have been recorded from Australia, but almost all records are from the nineteenth century, and can be discounted, as can the record of N. melinoides (Bull.) P.Kumm. by Mathieson (1946), which is by name only. One of the seven species, N. cerodes (Fr.) P.Kumm., is placed by some authors in Simocybe, for which there are confirmed Australian records based on other species. In the Northern Hemisphere Naucoria is associated with broad-leaved trees such as Salix, Alnus and Betula. It is possible that the genus occurs in Australia as an associate of exotic trees, but there are no recent records or herbarium material to confirm this. See also Recent reports yet to be verified.
