NatureServe Status

Global Status: G4G5
Global Status Last Reviewed: 29Mar2002
Global Status Last Changed: 29Mar2002
Rounded Global Status: G4 - Apparently Secure
Reasons: Fissidens hyalinus, a moss once considered very rare, is now known to be much more common. Collection and field efforts have located 65 new localities in the United States alone (Risk 2002). This small moss occurs in seven states in the United State, and throughout islands in southeast Asia, Australia, Borneo, Japan, and India. Risk (2002) also suggests "there are likely many undiscovered localities of F. hyalinus in the eastern United States". Furthermore, while its habitat requirements are somewhat specific, it is relatively easily found when the correct habitat is searched (Risk 2002).
Nation: United States
National Status: NNR

NatureServe Global Conservation Status Factors

Range Extent Comments: Fissidens hyalinus is found in the United States in seven states: Pennsylvania, Ohio, Kentucky, Tennessee, Alabama, Louisiana and Virginia. It is also found in other parts of the world including, Micronesia, Taiwan, India, the Fiji Islands, Malaysia, Vanuatu, Philippines, Japan, Australia, Borneo, Nepal and Java (Risk 2002).

Population Size Comments: In the past Fissidens hyalinus was thought to be "very rare (or overlooked)" (Reese 1984). A recent study has reported that this species is actually much common than once thought. In the United States, 65 new locations were discovered in the following states: Kentucky, Tennessee and Viriginia. In total, Fissidens hyalinus is now known from seven states in the United States: Pennsylvania, Ohio, Alabama, Kentucky, Louisiana, Tennessee and Virginia (Risk 2002). Risk (2002) also says "Is F. hyalinus rare? These collections and field experience suggest it is not when the apporpriate habitat is searched. The species was relatively easily found when sites meeting the aforementioned criteria were examined". The criteria Risk (2002) mentions is calcareous geology, intact and diverse overstory and a steep dissected landscape. Futhermore, Risk (2002) says that there are likely many more locations of F. hyalinus to be discovered in the eastern United States.

Basic Description: Mosses minute, pale-green or hyaline and exceedingly delicate, scattered or gregarious. Leaves in pairs, broadly oblong-lanceolate, acute and often minutely apiculate, entire, ecostate. Autoicous. Setae terminal, hyaline and delicate, bent at the base (Crum and Anderson 1981).
Habitat Comments: Fissidens hyalinus inhabits calcarous soils, in intact forests with overstory diversity associated with Braun's 1950 mixed mesophytic forest and a steeply dissected landscape. Further, F. hyalinus is absent from ridgetops and the upper slope areas (regardless of the geology) due to lack of moisture. At midslope where calcareous substrates are available F. hyalinus is found (Risk 2002).
