Russula fellea.

Again, another mushroom that need further study to get a right id., but according to our local field guide, and taking into account the other yellow russulas we have around here, I find Russula fellea the most convincing id.
Other species we have here, similar to this can be Russula farinipes, Russula ochroleuca and Russula sardonia viridis.

The mushroom Russula fellea goes by the common name of the geranium-scented Russula, or bitter Russule and is a member of the Russula genus, all of which are commonly known as brittlegills. It is straw or honey coloured and in Britain grows in beech woods during autumn. It is inedible.

Taxonomy

It was first described and named in 1821 by the Swedish mycologist Elias Magnus Fries, initially as Agaricus felleus, before being placed in the genus Russula in 1838. Its specific epithet is derived from the Latin adjective felleus meaning "biliary", in reference to its bitter taste, reminiscent of bile.

Description

The cap is usually 4–9 cm wide, and convex, flattening later, and often with a broad central boss (umbo). It is sometimes furrowed at the margin when mature. The similarly coloured, but paler stipe is firm and stout, and is 2–6 cm high by 1–2 cm wide. The gills are adnexed, and are the same colour as the stem, giving a spore print that is white to pale cream. The flesh is white, and does not change colour on cutting. It tastes hot, and often has a bitter tang. The smell is variously reported to resemble geraniums, or apple sauce.

Distribution and habitat

Russula fellea appears in autumn, and is found with beech (Fagus) in Britain, but in Europe it sometimes occurs with spruce (Picea). It is normally associated with well-drained acid soils, and is widespread in the northern temperate zones; Britain; Europe, and Asia. It is not present in North America where it is replaced by the closely related R.simillima.It grows in deciduous and coniferous woods, and forests.

Edibility

This mushroom is inedible, having a very hot bitter taste.

Hola Felipe,
La foto de la izquierda, es tan elocuente que hace que uno piense que se puede tocar el hongo!... la foto de la derecha tiene un POV útil pero más comprometido. Al mimo tiempo tiene un "pedacito"# de trasfodno maravilloso, llamativamente profundo!... buen trabajo con ambas fotos y exelente documento anexo. Saludos, Gracias por compartir, Jesús

Hi Felipe,

Beautiful pair of shots, with perfect ID specification. I must add this species is only growing on acid soil, mostly in broadleaved, rarely in pine forests and its odour always helps to isolate from similar species. Although I don't understand the sentence with the following name in your note: "...Russula sardonia viridis". Species with a name like this doesn't exist. Russula sardonia Fr. is not similar to this species at all with its purple cap - it's a character species of 2-needle pine forests (Pinus nigra, P. silvestris) on acid soils, while Russula viridis Cleland lives only in New Zealand (and maybe in Australia). Other Eurasian species to confuse with are Russula solaris Ferd. & Winge, sometimes with almost the same odour but with smaller size, and Russula raoultii Quél. with more white than yellow tones on the cap.

Thank You not only for sharing, but also for accepting my too scientifical style of critiquing in case of fungi photos. :) Best regards, László

Hi Felipe

Another lovely Spanish fungi for us to admire. Good POV on both shots and good light management. Good DOF and sharpness.

Chris

Hi Felipe & Cristina,
A lovely capture of this beautiful mushroom. Very well composed with good details. Thanks a lot for sharing.

Two great images showing the top and gills clearly.
Great exposure and sharpness in both images.
Excellent work.
Cheers
Steve
