Arrhenia retiruga

Arrhenia retiruga (Bull.) Redhead syn. Leptoglossum retirugum (Bull.) Ricken (illustrated life size) Cap 0.5–1.5cm across, cup-shaped then expanded, sessile, margin lobed; whitish-pallid, inner fertile surface whitish-grey, with often interconnected folds or wrinkles radiating from the centre. Spores 7–8×5–6¼, elliptical. Spore print white. Hyphae lacking clamp connections. Habitat usually on moss, very occasionally on dead grass or twigs; winter to spring. Uncommon. Not edible. Note this species is now considered to be a member of the Tricholomataceae and as such should be close to the main entry but it seems better to position it here amongst similarly shaped fungi.
