Musci, Gigaspermum, Italy.Palabras clave. Musci, Gigaspermum, Italia.During a series of studies conducted innorth-western Sicily in October 1996,Gigaspermum mouretii Corb. was gathered byA. Carratello in the periphery of the inhabitedcenter of the municipality of Capaci (Palermo)(38'10'93" N, 13°14'28"E). The species wasfound on a small piece of land (about 200m 2 )once used for pasture, at about 50 m from thesea and at 5 m a.s.1., with N-NW exposure.Its leaves are evenly spaced or crowded,almost orbicular, apiculate, concave and 0.7mm long (without the apiculus) (fig. I). Itsmargin is flat, smooth and somewhat crenulatein the upper part. Nerves are absent. Cells inthe basal part of the leaf are rectangular withsmooth walls; in the median and upper partthey are often partly hyaline, irregular torhombic. The perichaetial leaves are hyaline,green at the base, extending 2.5 mm long; theyare elongate-triangular, longly acuminate andstrongly concave, enclosing the whole capsule.The margin is flat, smooth in the lower half andslightly denticulate in the upper half. Its capsuleis sessile, gymnostomous, with a wide, slightly204	Acta Botanica Malacitana 23. 1998Figure 1.

The sporesare polyhedric, very large (ca. 130 [tm),brownish, almost smooth.All the plants were fertile and thesporophytes were found in abundance. Thearrangement of the gametangia was paroicous(antheridia in leaf axils, just beneath thearchegonia). This species is distinguished byits thick, hyaline, subterranean, rhizomatous,fragile stems and short gametophoresresembling buds.In the Capaci area Gigaspermum mouretiigrows on a shallow argillaceous-calcareoussubstratum with rocky outcroppings, where itforms dense gray-green tufts. The species isassociated with Bryunt caespiticium Hedw.,Didymodon vincalis (B rid.) R.H. Zander,Fissidens viridulus (Sw.) Wahlenb., Funariamuhlenbergii Turner, Pottia starckeatta(Hedw.) MOII.

All the specimensare deposited in the herbaria of the Universitiesof Palermo [PAL] and Camerino [CAME].Gigaspermum tnouretii is a rare oceanic-mediterranean species (Schumacker & Martiny,1995). Its first description, by Corbiére (1913),was for a specimen from Morocco. Later Heimgathered it in 1934 and Jelenc reported it in1955 in two other localities of Morocco. Thefirst report for the European continent was byAllorge & Casas (1958) in the Sierra del Cabode Gata (Spain). It was later found in othersites in Spain by Acuña et al. (1974), by Ros(1984), Ros & Guerra (1987) and by Rose116 inthe Balearic islands of Mallorca and Formentera(Casas eta!., 1985). More recent finding wereby Malme (1988) in the Canary islands, byDirkse & Bouman (1990) in Lanzerote and inTenerife and by Urmi in Crete (Gávdhos Island,near Kastri, Nomos Khanion, leg. E. Urmi 1983,Z). The species is known in several sites in Israel206	 Acta Botanica Malacitana 23. 1998(Herrnstadt et al., 1980, 1991). The report ofGigaspermum mouretii for Capaci is the first forItaly and extends the species' areal of distributionin the Mediterranean basin (fig. 2).In most of these locations the species wasalways found sterile, a condition which shouldbe related to the fierce aridity of the collectionsites. It is known that in certain regions withdry climates, the moss flora mainly consists ofsterile plants. In 1980, sporophytes ofGigaspermum mouretii were found inabundance in one locality of Israel wherecollections made in previous years had nosporophytes. The unusual winter of 1970-80had a long and continuous moist period andprobably allowed unusual sporophytedevelopment (Hernnstadt et al., 1980).In the Capaci site Gigaspermum tnouretiiwas gathered with sporophytes in September-October with the first autumnal rains. Thearea's climate, though it has typicallymediterranean characteristics, presents an ave-rage annual rainfall of about 700 mm, withaverage monthly temperatures above 10°Cwhich, in the period from May to September,exceed 20°C. A series of mountainous reliefsimmediately inland greatly attenuates theimpact of the hot African winds and in factblocks the establishment of a decidedly aridclimate. Only the presence of a not particularlyarid climate, characterized by a moderategradient of humidity seems to be the basis forthis species' sporification.Gigaspermum mouretii is also of interestfrom the phytogeographic point of view.All the species of this genus are distributedin the Southern Hemisphere (southern Africa,Madagascar, Australia, Tasmania and NewZealand); Gigaspermum mouretii, on the otherhand, has a mediterranean distribution and thusrepresents a very important horco-australdisjunction (Allorge, 1931; Casas eta!., 1981).Some hypotheses can be advanced toexplain the finding of Gigaspermum mouretiiin the Capaci area.First, the spores could have been carriedby the hot African winds full of sand whichperiodically blow over the zone and stop nearthe mountainous reliefs which surround theCapaci basin.Second, the spores may have beendispersed by the air traffic and tourism whicharrives in the zone through the nearby Palermoairport, from Spain, the Canary Islands andfrom the nearby African countries.Further research to identify newGigaspermum mouretii sites has so far failed andseems to confirm for the moment these hypotheses.AKNOWLEDGMENTS.
