Thaxterogaster austrovaginatus is a species of ectomycorrhizal fungus in the famlily Cortinariaceae. [1]
It was originally described by Bruno Gasparini in 2007 and classified as Cortinarius austrovaginatus based on a holotype specimen collected by mycologist Genevieve Gates at Jackson's Bend, Mt Wellington, Tasmania, Australia. [2] The species also occurs in New Zealand, where it is reported to have a semi-secotioid habit. [3] Cortinarius austrovaginatus was placed in Section Austrovaginati, along with two New Zealand species C. conei and C. medioscaurus. [3] This Section is of interest because it contains an agaricoid (C. medioscaurus), semi-secotioid (C. austrovaginatus) and a secotioid (C. coneae) species. [4]
In 2022 the species was transferred from Cortinarius and reclassified as Thaxterogasteraustrovaginatus based on genomic data. [5]
The pileus of Thaxterogaster austrovaginatus is up to 60 mm in diameter, with a viscid cuticle, fibrillose, the colour ranges from brown/vinaceous to pale lilac-brown with buff margin, and the cap has remnants of the white veil stained with the rusty spores. The lamellae are close, moderately thick, adnate, livid vinaceous when young and lilac brown at maturity. The gill margin is heterogeneous, whitish irregular and crenulated. The stipe is 30–36 mm tall and 8–12 mm wide, robust, fibrillose, cylindrical, lilac to livid vinaceous, with heavy rusty chocolate-brown spore deposit, densely covered with velar remains. The bulb is marginate, ampullaceous to slightly turbinate, violet, but covered with a white sheath of the universal veil forming a volva. The universal veil is white and submembranaceous. The cortina is white, abundant and permanent. The cap tissue does not react to the application of alkali solutions. [2]
The species was described from Nothofagus forests in Tasmania. [2] In New Zealand it has myrtaceous hosts. [3]
The specific epithet austrovaginatus is derived from the Latin austro, meaning from the south, and vaginatus, meaning sheathed, and it refers to this species being a southern species similar in appearance to the South American species, Cortinarius vaginatus .
The Cortinariaceae are a large family of gilled mushrooms found worldwide, containing over 2100 species. The family takes its name from its largest genus, the varied species of the genus Cortinarius. Many genera formerly in the Cortinariaceae have been placed in various other families, including Hymenogastraceae, Inocybaceae and Bolbitiaceae.
Phlegmacium triumphans, also known as the birch webcap, or yellow girdled webcap is a basidiomycete mushroom in the family Cortinariaceae. It is found in Europe and regarded as edible by some authorities, although others call it suspect and it resembles inedible species.
Thaxterogaster purpurascens is a species of mushroom producing fungus in the family Cortinariaceae. It is commonly known as the bruising webcap.
Cortinarius anomalus, also known as the variable webcap, is a basidiomycete fungus of the genus Cortinarius. It produces a medium-sized mushroom with a grayish-brown cap up to 5 cm (2 in) wide, gray-violet gills and a whitish stem with pale yellow belts below. The mushroom grows solitarily or in scattered groups on the ground in deciduous and coniferous forests. It is found throughout the temperate zone of the northern hemisphere.
Cortinarius porphyroideus, commonly known as purple pouch fungus, is a secotioid species of fungus endemic to New Zealand. It was one of six species that appeared as part of a series depicting native New Zealand fungi on stamps, released in 2002.
Cortinarius camphoratus, commonly known as the goatcheese webcap, is an agaric fungus in the family Cortinariaceae. The fungus is found in Europe and North America, where its fruit bodies (mushrooms) grow on the ground in a mycorrhizal association with spruce and firs in coniferous forests. Mushrooms are characterized by pale blue lilac colors when young, and a strong distinctive odor. Sources disagree as to the edibility of the mushroom, but they are generally not recommended for eating.
