🧠 Report on the zoological collections made in the Indo-Pacific Ocean during the voyage of H.M.S. 'Alert' 1881-2. London: Printed by order of the Trustees, 1884. [Source]

Illustration from an 1884 zoological report showing detailed scientific drawings of three crab species collected during the Indo-Pacific voyage of H.M.S. Alert. The central focus includes full views and close-ups of claws and carapaces labeled A (Euxanthus tuberculosus), B (Hypocoelus punctatus), and C (Banareia inconspicua). The finely stippled engraving highlights surface textures, tubercles, and anatomical features with labeled parts such as claws and carapace sections. This historical plate reflects 19th-century taxonomic study methods, linking to Darwin’s legacy of natural history exploration and species documentation.

A new book on British Earthstars by Jonathan Revett is now available to preorder from @summerfieldbooks.com #MycoBookClub #fungi #FungiFriday #Mycology www.summerfieldbooks.com/product/brit...

14. Geastrum rufescens Pers.

Rosy Earthstar

<<< rufescens = red, reddening >>>

Icons: Pegler et al. (1995) p103; Jeppson (2013) p168; Læssøe et al. (2019) p1249.

A medium to large sized species with thick fleshed pinkish-red non-hygroscopic rays, a fimbriate peristome and stalked spore sac

Unexpanded fruitbody: Subglobose, 30mm 40mm.

Expanded fruitbody: 50mm - 90mm with 5-8 non-hygroscopic rays, flattened or arching with age.

Mycelial layer: Persistent, encrusting debris.

Fibrous layer: Pale grey brown

Fleshy layer: Warm reddish pink, flesh up to 8mm thick when fresh, quickly cracking and falling apart, darker with age but normally with residual reddish tones.

Spore sac: Subglobose 10mm 30mm diameter, greyish buff or light brown, smooth or minutely hairy (hand lens needed!) and with a fimbriate peristome which is often ill-defined and a short stem.

Mature Spore Mass: Dark brown.

Spores: Globose, 3.8µm 4.3µm, covered in elongated warts up to 0.5µm high.

Capillitial hyphae: 4.0µm 8.0µm, thick walled, tapering, encrusted.

Habitat: Rich litter in both deciduous and coniferous woodland, parks, arboretums.

Distribution: An uncommon species but well represented across Britain.

Discussion:

Unmistakable when fresh, thick fleshed with some degree (often very intense) of pinkish red tones and a weakly defined fimbriate peristome. The spore sac often degrades very quickly, especially around the peristome and can end up with several tears and holes. The short stem is best seen in mature specimens when all the flesh has eroded.

Unlikely to be confused with other earthstars when fresh but old specimens can resemble Geastrum michelianum or even Geastrum fimbriatum however the rays normally have dark reddish tones and sometimes dried patches of the thick flesh. The spores are also larger than G fimbriatum & G michelianum.

Often found in and around rotting tree stumps or on big thick piles of needle litter.

European Distribution & Species:

Common and widespread a…
