Arachnion is a genus of gasteroid fungi in the family Agaricaceae.

Taxonomy

The genus was circumscribed by Lewis David von Schweinitz in 1822 with Arachnion album as the type, and only species.[3] The genus name is Greek for "cobweb".

William Chambers Coker and John Nathaniel Couch circumscribed the family Arachniaceae in 1928 to contain Arachnion.[4] The genus was later placed in the now-defunct family Lycoperdaceae.[5] Modern molecular analysis has shown that Arachnion, as well as other puffball genera, are part of the family Agaricaceae.[6]

Description

Arachnion species have a characteristic gleba, resembling a mass of grainy, sand-like particles. At a microscopic scale, the granules are peridioles, or tiny sacs made of hyphae that contain spores. Inside each sac is a minuscule chamber that contains inward-facing basidia (spore-bearing cells), an arrangement similar to that seen in Lycoperdon. The fruitbodies have a smooth, thin, and fragile peridium that readily disintegrates into small pieces in maturity to expose the granular contents.[4]

Distribution

The genus is widely distributed, with species found in Australia, North and South America, South Africa, and Europe, and Japan.[7]
