Trichoglossum walteri is a
IUCN Red List of Threatened Species.[1]
Taxonomy
The species was first
sensu lato is not closely related to the type species of Trichoglossum, but belongs in a separate genus as yet not formally named.[2]
Description
setae are present. The asci are 8-spored, the ascospores 90–100 × 4.5–5.5 μm, becoming 7-septate at maturity.[2] North temperate collections differ in being larger, up to 100 mm (4 in) tall, and in having shorter ascospores, 75–85 × 4.5–5.5 μm.[2]
Similar species
All Trichoglossum species appear similar in the field and can only be identified by microscopic examination. In European grassland, the short-spored earthtongue is most easily confused with the much commoner Trichoglossum hirsutum which has longer spores that become 15-septate at maturity.
Conservation
In Europe the short-spored earthtongue is typical of waxcap grasslands, a declining habitat due to changing agricultural practices. As a result, the species is of global conservation concern and is listed as "vulnerable" on the IUCN Red List of Threatened Species.[1]
