Resumen: Catálogo de los hongos del Parque Nacional Iguazú (Misiones, Argentina). Este catálogo de los hongos registrados para el Parque Nacional Iguazú, una de las áreas preservadas mejor conocidas en América del Sur, ha sido confeccionado principalmente sobre la base de las colecciones y publicaciones de Rolf Singer y las propias. Diez especies de Dictyosteliales, 4 de Myxomycetes, 4 de Pezizales, 9 de Hypocreales, 31 de otros Ascomycetes, 3 Deuteromycotina, y 314 de Basidiomycetes han sido anotadas. Este último grupo es de lejos el mejor conocido, e incluye 13 especies de hongos gelatinosos, 6 de hongos clavarioides, 84 de resupinados, 90 de Agaricales s. l., 111 de políporos, de los cuales 26 son Hymenochaetaceae poroides, y 11 de Gasteromycetes. Además, 8 Ascomycetes, 58 Basidiomycetes y 2 Deuteromycotina fueron solo determinados a nivel de género. Los líquenes han sido excluídos. Los microhongos del Parque apenas han sido explorados, y no se han registrado 'ficomicetes', de modo que el número de especies que se presenta aquí son tan sólo un mero muestreo de la micobiota del Parque.

Palabras clave: Biodiversidad; Hongos; Subtrópicos.

Summary: A check-list of the fungi recorded from Iguazú National Park, one of the best known preserved areas in South America, has been compiled mainly on the basis of Rolf Singer´s and our own collections and publications. Ten species of Dictyosteliales, 4 of Myxomycetes, 4 of Pezizales, 9 of Hypocreales, 31 of other Ascomycetes, 3 Deuteromycotina and 314 of Basidiomycetes are annotated. This last group is by far the best known, and includes 13 species of jelly-fungi, 6 coral fungi, 84 resupinates, 90 Agaricales s. l., 111 polypores of which 26 are poroid Hymenochaetaceae, and 11 of Gasteromycetes. Furthermore, 8 Ascomycetes, 58 Basidiomycetes and 2 Deuteromycotina were determined to genus. Lichens have been excluded. The microfungi of the Park have hardly been explored, and no phycomycetes are recorded, so the number of species included in this checklist is but a mere sample of the rich mycobiota of the Park.

Key words: Biodiversity; Fungi; Subtropics.

INTRODUCTION

Iguazú National Park is part of the subtropical rain forest phytogeographically belonging to the Paranaense Region (Cabrera,1976). Together with the Yungas region, it is the biologically richest natural area of Argentina. It covers an area of ca. 65.000 ha, and is located in the northernmost part of NW Misiones Province (25° 32' to 25° 44' S lat; 54° 09' to 54° 33' W long) (Fig. 1). Joining it at the boundary between Argentina and Brazil, is the Brazilian Parque Nacional do Iguaçu, covering ca.160.000 ha. Annual rainfall averages 2000 mm, quite uniformly distributed throughout the year. The relative humidity (RH) is enhanced by heavy nocturnal dew, so its mean RH is 75-90%. Temperatures vary much from day to night in summer and winter, 15 °C mean for June-July and 25 °C for December-January. Absolute temperatures have reached 42 °C in summer and -6 °C in winter. Soil is typically lateritic (Dimitri et al., 1974). A series of ongoing surveys of the Park's biodiversity has made it one of the best known conserved areas in South America. However fungi, especially microfungi, have been neglected and still await extensive studies.

This important natural reserve was bought by the Argentine National Government in 1928, and incorporated in the National Park Service in 1935; so, notwithstanding the previous commercial exploitation of the rich forest, it has slowly recovered to what may termed a near climax vegetation.
The several strata that make up this climax forest are home to a wealth of fungal species. Although tree species probably number more than one hundred - the vascular flora is still currently under study - outstanding among them are Myrocarpus frondosus, Parapiptadenia rigida, Lonchocarpus muehlbergianus, Enterolobium contortisiliquum, Holocalyx balansae, Cedrela tubiflora, Patagonula americana, Rapanea lorentziana, Nectandra lanceolata, Chrysophyllum gonocarpum, Ocotea pulchella, Tabebuia ipe, Aspidosperma polyneuron, Adenanthera macrocarpa and O. trichotoma. One palm - Syagrus romanzoffianus - is striking on account of its gracile stipe. Arborescent ferns are common, such as Alsophila atrovirens, reaching up to 5 m in height. The tree stratum in less perturbed areas may reach 30 m high.
The understory contains many herbaceous and subshruby species including a wide variety of bamboos (Chusquea ramosissimam, Merostachys claussenii and Guadua trinii). Of course, there is also a wide array of epiphytes, orchids, Bromeliaceae, and hundreds of species of animals, including birds and arthropods.
Human activity, mainly due to the tourist invasion which expanded greatly after 1995 (6000/ day in 2001), and the ever-expanding "facilities" is a constant threat to this magnificent area.
The magnificent Iguazú Falls ("big waters" in guaraní language), discovered by Don Alvar Núñez Cabeza de Vaca (the same formidable "conquistador" who also wandered from Florida to New Mexico and Colorado), was originally called "Saltos de Santa María". The Falls form an arch of some 200 falls - the highest 70 m - due to a large semicircular fault 2700 m wide in the Iguazú River at the international boundary between Argentina and Brazil. The river flows from the Serra do Mar, in eastern Brazil, at 1300 m.a.s.l. to the west for some 500 km, towards the Paraná River at 90 m.a.s.l.; the fault is located 28 km from the mouth of the Iguazú River.
This wonderful natural area is a mycologist's paradise. We have been studying its mycobiota for the past 36 years and, although partial results have already been published, mainly for macromycetes by Corner (1957), Job (1985), Hjortstam & Ryvarden (1986), Rajchenberg (1982, 1984), Wright, Deschamps & Rovetta (1973), Wright & Deschamps (1975, 1976/77), Wright & Blumenfeld (1984a,b), Wright, et al. (1985); Singer (1950, 1952, 1958a,b, 1961a, 1961b, 1965, 1970, 1973, 1976), Singer & Digilio (1951), Romero & Gamundí (1986), no checklist of the fungi found in the Park has been published. Thus, no conspectus or guide is available for the Park's exceptional fungal biodiversity. The following checklist aims to form the basis for the needed aditional taxonomic, biodiversity and ecological studies of the fungi of Iguazú.

MATERIALS AND METHODS

The present paper is based mainly on the numerous collections at BAFC - which also include many of Dr. Rolf Singer's collections- and a list kindly supplied by Dr. Egon Horak (ETH, Zurich), together with the scant information obtained from the literature. Many collections have only been identified to genus. Names of genera and species have been updated as far as feasible. We feel, however, that the present checklist will constitute a basic contribution for the development of further and hopefully more precise studies. Suprageneric taxa follow Ainsworth & Bisby's "Dictionary of the Fungi" (Hawksworth et al.,1995).
Collections without herbarium citation are housed at BAFC, and their herbarium number is given in parentheses; other collections are indicated following Holmgren et al. (1990). Common collecting sites are indicated with site numbers given on the map (Fig. 1). Less common localities are indicated by their name or, in some instances, with no information.

CONCLUSIONS

The present check-list contains a total of 330 specific and infraspecific named taxa, of which the majority belong to Stereales (67), Hymenochaetaceae (43), Poriales (68), and Agaricales s. l. (90), of which the Tricholomataceae Comprise 61 taxa. Some groups are extremely underrepresented due to lack of adequate study, namely, the Ascomycota as a whole (with only 35 taxa), the Phragmobasidiomycetes (with 16), the Clavariaceae s. l. with a scant 3, the Myxomycota (with only 4), and the Lycoperdales (also with 8). The group that has received most study are the Aphyllophorales, which account for almost half of the total of identified taxa. The abundance of Hymenochaetaceae is remarkable. A novelty is the inclusion of slime-molds, which produced so far 10 taxa.

ACKNOWLEDGEMENTS

We wish to express our appreciation to the numerous persons who have contributed to this work, particularly Mrs. Laura Del Busto, for tedious bibliographical searches, the Argentine National Park Service, for authorizing collecting trips of the senior author to the Iguazú Nat´l Park and other facilities, which included two international work-shops in 1980 and 1981, with the assistance of Drs. E. Horak (Zurich) and L. Ryvarden (Oslo), respectively, in the collection and identification of numerous specimens. These collecting trips were shared with Dr. J. R. Deschamps, the late Mr. E. Del Busto, the late Lic. C. E. Gómez and Dr. Daniel Cabral, whose unflinching enthusiasm laid the foundations for this work. More lately, field trips were undertaken with the youthful company of Drs. Orlando F Popoff and Bernardo E. Lechner. This research was funded by the University of Buenos Aires, the U.S. National Science Foundation (1961), the Myls Pedersen Botanica Foundation and the Argentine Nat´l Research Council throughout the years, and constitutes Paper no.160 of the PRHIDEB-CONICET. We wish to express also our deep appreciation to Dr. R. H. Petersen (University of Tennessee), for making available his data-base of Argentine fungi to us and for reading the original draft of this paper and making valuable suggestions. Mr. A. de Meijer (Curitiba) is acknowledged for pertinent corrections concerning some species.
