Le genre Pilat (Basidiomycotina)

Host-exclusivity and host-recurrence by wood decay fungi (Basidiomycota - Agaricomycetes) in Brazilian mangroves

“…The Georgea S. Nogueira-Melo, Paulo J. P. Santos and Tatiana B. Gibertoni other species are considered host-generalists, (including G. striatum, which in the current study was host-exclusive in R. mangle), being mentioned previously in other hosts when collected in high-diverse ecosystems (Ryvarden & Johansen 1980;Hjortstam et al 1987;Gilbertson & Ryvarden 1986;Hjortstam & Ryvarden 1990;Boidin et al 1997;Boidin & Giles 2000;Lindblad 2000). The data here presented may support the hypothesis of Gilbert & Sousa (2002) that in environments of low diversity, such as mangroves, the differential occurrence of a fungus in a host may happen more easily, since in those environments plant diversity is low and, therefore, the number of suitable host plants is higher.…”

“…Color designation followed Watling (1969). The material was identified using specialized literature (Ryvarden & Johansen 1980;Gilbertson & Ryvarden 1986;Hjortstam et al 1987;1988;Hjortstam & Ryvarden 1990;Boidin et al 1997;Boidin & Gilles 2000;Ryvarden 2004) and incorporated to the Herbarium URM. The nomenclature for Agaricomycetes followed the Index Fungorum (www.indexfungorum.org).…”

Corticioid fungi (Basidiomycota) in mangrove forests of the islands of Iriomote and Okinawa, Japan

“…This species has been reported from Guadeloupe Island in the Caribbean Sea (Boidin et al 1997), Tanzania (Hjortstam and Larsson 1995), and Florida and Mississippi in the United States (Ginns and Freeman 1994). There are different opinions on the disposition of this species.…”

“…Notes: This species is characterized by its loosely intertwined subicular hyphae with clamp connections, cylindrical to obclavate gloeocystidia with a stalklike base, and minutely warted ellipsoid and amyloid basidiospores measuring 4.5-5.5 ϫ 3-4 µm. It has previously been reported only from Réunion Island in the Indian Ocean (Boidin et al 1997) and Taiwan (Wu 1996).…”

“…because of the presence of acanthohyphidia, clampless hyphae, and smooth, amyloid basidiospores. Recently, Larsson (2002) suggested that this species should be transferred to Megalocystidium Jülich based on the phylogenetic analyses using sequence data of the nuclear 5.8S, internal transcribed spacer region 2 (ITS2), and large subunit rDNA genes, although acanthohyphidia have not been described as one of the generic characteristics of Megalocystidium in Jülich's original description (1978) and subsequent descriptions by Ginns and Freeman (1994), Wu (1996), and Boidin et al (1997). Basidiomata resupinate, adnate, at first orbicular and then becoming confluent, 70-250 µm thick; hymenial surface dull cream to "Buff", smooth, pilose under the lens (ϫ20); margin white to "Buff", thinning out indeterminately, sometimes pruinose to fibrillose under the lens (ϫ20).…”
