项目摘要

Many fungi of Aphyllophorales (Basidiomycotina) have been described by several mycologists from the subtropical areas of Japan, but corticoid fungi (Corticiaceae sensu lato) not known except for several species. The aim of this study was to collect corticoid specimens and isolates from the susbtropical areas including mangrove forests and to carry out their morphological and phylogenetic analyses. In this study, I collected 425 corticoid specimens and 235 isolates. Morphological analyszes revealed that 93 species belonging to 45 genera were distributed in the subtropical areas of Japan. Among these species, the following ten species were recognized as the previously unrecorded from Japan : Asterostroma muscicola, Cerocorticium molle, Gloeocystidiellum moniliforme, G. wakullum, Hyphoderma ayresii, Phanerochaete tropica, Phlebia acanthocystis, Resinicium friabile, Trechispora stevensonii, and Vararia gittoni. Furthermore, one new genus, Haloaleurodiscus, and two new species, H. mangrovei and Asterostroma macrosporum, were proposed based on ribosomal DNA (18S, 25S and/or ITS1-5.8S-ITS2) sequence analyses, and morphological and ecological characteristics of the corticoid fungi collected from the mangrove forests. Further morphological and phylogenetic studies on the many specimens unidentified in this study are required to elucidate floristic of the corticoid fungi in subtropical areas of Japan.

许多非担子菌目真菌(担子菌目)已被日本亚热带地区的几位真菌学家描述，但皮质类真菌(Cortisaceae Sensu Lato)除了几个种外，还没有被发现。本研究的目的是从包括红树林在内的热带地区收集皮质激素标本和分离物，并对其进行形态和系统发育分析。在本研究中，我收集了425份皮质激素标本和235株分离物。形态分析表明，日本亚热带地区有分布于45属93种。在这些种中，有以下10种为日本以前未记录的种：Asterostroma muscicola、Cerocortis molle、Gloecystidiellum moniliforme、G.wakullum、HyPhoderma ayresi、Phanerochaete tropica、Phlebia Acanthcystis、Resinicium Friabile、Trechispora stevensonii和Vararia gittoni。根据核糖体DNA(18S、25S和/或ITS1-5.8S-ITS2)序列分析，结合采集自红树林的皮质类菌的形态和生态学特征，提出了1个新属--Haloalurodisus和2个新种：H.mangrovei和Asterostroma macporum。需要对本研究中未鉴定的许多标本进行进一步的形态和系统发育研究，以阐明日本亚热带地区皮质类真菌的区系。
