Fourteen species (8 genera, 3 families) belonging to the order Phallales in Taiwan were comfirmed by a fieldwork in 2008 as well as herbarium and literature searches. One species, Phallus impudicus, is newly reported from Taiwan. Key words : distribution, fungi, mushrooms, stinkhorns, taxonomy. genera Protubera (Malloch, 1989), Gelopellis Introduction (Beaton & Malajczuk, 1986) and Phallobata The order Phallales was originally described (Castellano & Beever, 1994), are closely related by Fischer (1900) to accommodate taxa common- to stinkhorn taxa. ly referred to as stinkhorns (family Phallaceae) Molecular phylogenetic studies clearly demon- and lattice stinkhorns (family Clathraceae). strated that stinkhorns are closely related to mor- Both families produce epigeous fruit bodies with phologically and ecologically distinct taxa, such spongy structures, which allow them to grow as earthstars (Geastrales), coral and club fungi rapidly when they absorb water from surrounding (Gomphales) (Humpert et al., 2001; Hosaka et environment. Most notably, their spore masses al., 2006). Currently, Phallales is recognized as a (glebae) become slimy and emit distinct odor well-supported monophyletic group with six (often described as “fetid”, “obnoxious”, or “un- well-supported subclades within it (Hosaka et al., pleasant”) when matured (Arora, 1986).

It is noteworthy that three basal clades been considered that the odor attracts small in- within Phallales were characterized by truffle- sects, especially flies, and their spores are dis- like taxa, indicating that stinkhorn-like fruit bod- persed by those insects (Fulton, 1889).

Hosaka et al. stinkhorns has been well-known for more than a (2006) also discussed the possibility that spore century, and virtually all species belonging to dispersal of Phallales, including truffle-like taxa, Phallaceae and Clathraceae depend on insects as is entirely dependent on arthropods. spore dispersal agents (Fulton, 1889). For many species of stinkhorns, the center of Cunningham (1931) first recognized that some diversity lies in tropical regions of the world taxa with non-stinkhorn-like fruit bodies, i.e., (Dring, 1980). The presence of many (presum- Claustulaceae, should also be included in the ably) endemic taxa in tropical regions, such as order Phallales. This monotypic family, which Africa (Dring, 1964, 1980; Dring & Rose, 1977), contains a genus Claustula, is characterized by West Indies (Dennis, 1953), Central America having sequestrate or truffle-like fruit bodies, and (Miller et al., 1991) and Yunnan, China (Zang & the gleba is enclosed by peridium and never ex- Petersen, 1989), is consistent with the hypothesis posed to the air. Subsequent studies also revealed that the origins of many, if not all, species of that more sequestrate or truffle-like taxa, such as stinkhorns are tropical areas.
