Description
editIts cap is 5-20 mm and hygrophanous, becoming dark grey and translucently striped when wet, and paling to a grey-brown when dry. It is spatula or funnel shaped and its texture is smooth.[2] The hymenophore has branched grey veins, that with age anastomose. They are adnexed to the stipe. The stipe is 2-3 x .5-1.5 mm. The flesh smells like geranium leaves. [3]
The spore print is white. The spores measure 7-10 by 4-6.5 μm. and teardrop shaped. The basidia have 4 spores each and measure 28-34 x 7-10 μm. They have straight to curved sterigmata. Cheilocystidia are absent. Clamp connections are absent in all tissues. [1]
Ecology
editArrhenia spathulata grows on Tortula ruralis var. ruraliformis. It is common on coastal dunes in the Netherlands. It grows from October to January. [1]
