Abstract A list of ascomycetes and anamorphic fungi collected in Yakushima Island in the exploration in 2005 is provided. In total 68 genera 82 taxa (41 genera, 49 taxa in 9 orders of ascomycetes and 27 genera in 33 taxa of anamorphic fungi) were recognized. Seven anamorphic
fungi was recognized as new records from Japan. The mycobiota of Yakushima embraced both
temperate and subtropical fungi, but characterized mainly by subtropical elements.
Key words : anamorph, checklist, mycobiota, local inventory, new records.
Introduction
Materials and Methods
Due to heavy rain fall and diversified flora distributed in small area with relatively high altitude
difference, Yakushima Island has drawn attention
by mycologists. Mycological explorations have
been done for rusts (Morimoto, 1953; Hiratsuka
et al., 1955), sooty moulds (Katumoto, 1958,
1965, 1975), and wood parasites (Katsuki, 1965;
Kobayashi 1976, 1977). Otani and Tubaki (1976)
presented a preliminary list of discomycetes and
anamorphic fungi, in which 18 discomycetes and
33 anamorphic fungi were listed, but many additions are required. In the course of a research
program of the National Museum of Nature and
Science (Taxonomic research for plants and
fungi in areas with remarkable biodiversity in
Japan), Yakushima was visited in the autumn of
2005. In this paper, additional records of ascomycetes and anamorphic fungi are presented
with taxonomic notes. A list of aquatic hyphomycetes, hitherto unexplored in Yakushima,
will be given elsewhere.
For ascomycetes, isolation was attempted
when possible, to examine the anamorph. Isolation procedure followed Hosoya (1997) and
Tanaka and Harada (2003). The isolates were
cultured on potato dextrose agar (PDA; Nissui,
Tokyo), modified Weitzman-Silva-Hutner medium (WSH; oatmeal 10 g, KH2PO4 1 g,
MgSO4 · 7H2O 1 g, NaNO3 1 g, agar 20 g and distilled water 1000 ml) plate, and Miura’s agar
(glucose 1 g, KH2PO4 1 g, MgSO4 · 7H2O 0.2 g,
KCl 0.2 g, KNO3 2 g, yeast extract 0.2 g, agar
13 g, distilled water 1000 ml; pH adjusted to
6.5–7.0) at 23°C to examine the anamorph. Specimens were desiccated by heat after isolation.
Specimens are deposited in the herbaria of Hirosaki University (HHUF) or National Museum
of Nature and Science (TNS).
Enumeration of the species

Discussion
Although the above list includes some specimens unidentified at the species rank, 82 taxa
distributed among 68 genera were recognized.
These include 41 genera, 49 taxa assigned to 9
orders of ascomycetes and 27 genera 33 taxa of
anamorphic fungi (excluding those induced from
the teleomorphs). The collected ascomycetes
were classified to Helotiales, Hypocreales, Hysteriales, Patellariales, Pezizales, Pleosporales,
Rhytismatales, Sordariales, and Xylariales.
Both temperate and subtropical fungi were
recognized, suggesting a complex mycobiota in
Yakushima, but the mycobiota was characterized
mainly by fungi in subtropical areas (such as
Boedijnopeziza insititia, Byssosphaeria schiedermayeriana, Lachnum palmae, L. varians, Nectria
pseudotrichia, Rhytidohysteron rufulum and
Wiesneriomyces javanicus). Although several
taxonomic entities were recognized, identification of species in large genera that await mono-
53
graphic work (such as Orbilia and Mollisia) was
reluctantly left in the present study due to the
lack of sufficient information. Among the fungi
collected in the present study, the followings are
noteworthy.
The following three anamorphs were induced
on at least one of the media examined. Strossmayeria sp. (TNS-F-13491) produced a Dactylaria-like anamorph on Miura’s agar. The
anamorph is similar to Dactylaria in having
clavate, one to several septate conidia, but differs
in lacking discrete conidiophores. The teleomorph differs from hitherto known Strossmayeria in the aseptate ascospores, but the ectal excipulum structure best agrees with that of Strossmayeria. Although the distribution is wide,
records of Strossmayeria is relatively limited in
Japan (Hosoya, 2000). Further examination is required to settle the taxonomic position of this
fungus. Calonectria sp. (TNS-F-13539) revealed
a Cylindrocladium anamorph on all the media
examined, but produced conidia best on PDA.
Nectria pseudotrichia produced a synnematous
anamorph, Tubercularia lateritia (Berk.) Seifert,
on all the media.
The occurrence of Kirschsteiniothelia incrustans, the teleomorph of Dendriphiopsis atra
(Corda) Hughes, was first recognized in the present study in Japan (Tanaka and Hosoya, 2006),
although the anamorph has been known previously (Otani and Tsubaki, 1976). For fungi with
anamorphs, the difference of distribution is
known between teleomorphs and anamorphs
(Nakagiri and Tubaki, 1985). For these fungi,
comparison of teleomorphs and anamorph distribution will be an intriguing subject.
Bactrodesmium microleucurum, Canalisporium exiguum, Pestalotiopsis maculiformans,
Spadicoides bambusicola, Acrogenospora altissima, Endophragmiella ontariensis and Pleurophragmium simplex are new records from
Japan. Detailed morphological descriptions of
these species will be given in a separate paper
(Tanaka, in preparation). Canalisporium exiguum
was first found on submerged wood in Australia,
and believed to have a fresh water habitat (Goh et
54
Hosoya and Tanaka
al., 1998; Hyde and Goh, 1998), but recently reported as a seed decay fungus (Samrithipol et al.,
2004). The present material (TNS-F-12450) was
found on dead leaves of Alpinia speciosa, suggesting wider host selectivity of this fungus.
