Шаблон:Short description Шаблон:Speciesbox

Auricularia angiospermarum (wood ear or tree ear) is a species of fungus in the family Auriculariaceae. Basidiocarps (fruitbodies) are gelatinous, ear-like, and grow on dead wood of broadleaf trees. It is a North American species and was formerly confused with Auricularia auricula-judae which is confined to Europe.

Taxonomy

The species was originally described in 2015 from Connecticut on a fallen oak trunk. It had previously been referred to Auricularia americana 'deciduous unit',[1] but additional molecular research, based on cladistic analysis of DNA sequences, has shown that Auricularia angiospermarum is a distinct species.[2][3]

Description

Auricularia angiospermarum forms thin, brown, rubbery-gelatinous fruit bodies that are ear-shaped and up to Шаблон:Convert across and Шаблон:Convert thick. The fruitbodies occur singly or in clusters. The upper surface is finely pilose. The spore-bearing underside is smooth.[3]

Microscopic characters

The microscopic characters are typical of the genus Auricularia. The basidia are tubular, laterally septate, 45–65 × 3.5–5 µm. The spores are allantoid (sausage-shaped), 13–15 × 5–5.5 µm.[3]

Similar species

In North America, Auricularia americana is almost identical but grows on conifer wood.[2][3] On wood of broadleaf trees, Auricularia fuscosuccinea occurs in southern North America and typically has cinnamon-brown to purplish-brown fruitbodies.[1] Auricularia nigricans is also southern, but has a densely pilose upper surface.[1]

Habitat and distribution

Auricularia angiospermarum is a wood-rotting species, typically found on dead attached or fallen wood of broadleaf trees. It is widely distributed in North America, but is not currently known elsewhere.[3]
