Austroboletus occidentalis

Austroboletus occidentalis, commonly known as the ridge-stemmed bolete, is a species of bolete fungus found in Australia. It was described as new to science in 1986 by mycologists Roy Watling and Norma M. Gregory. The species name occidentalis is derived from the Latin occidens "west".. The fruit body has a 5.5–10 cm diameter cap that has a texture reminiscent of suede or chamois and can be sticky/slimy when young. Initially orange- or pinkish-brown, it is subconical with a thickened margin, and flattens with age and fades an ochre colour. Like other boletes, it has tubes under the cap instead of gills. These are white in young specimens maturing to pink. The cylindrical white stipe is 7–16 cm tall and 1.7–2.5 cm wide, marked with deep lacunae. The white flesh bruises yellowish and has a bitter taste. The edibility is unknown. The spore print is brown, the spores are cylindrical, 15–19 x 5–6.5 μm and covered entirely with warty lumps. Austroboletus occidentalis is a component of jarrah......read more on Wikipedia.
