| Morphological Description
|
Blackish dark brown central stem/stripe with an average length and width of 69.3 mm x 3 mm and tough flesh. The rim/edge of the cap is tan (light brown), and the top of the cap is yellowish brown top. The overall cap is rust-dark brown with a conical/bell shape and a smooth texture. The hygrophanous is present. The average pileus width is 21 mm, and the average pileus context thickness at the disc is 10.3 mm. The odour is akin to the cucumber/rind of a watermelon. The hymenophores are light cream-brown, crowded gills with free attachment and broad thickness. Although the spore print colour is pinkish-brown, the spore is oval shaped with a clear whiteish colour, absent ornamentation, thick-walled, and a present apical pore. The average spore length and width is 7.5 um x 5 um. The reaction Melzer’s colour is reddish-brown. The bean-shaped pleurocystidia length and width are 12.5 um x 7.5 um. The cheilocystidia length and width are 32.5 um x 10 um, lemon-shaped with a curved rounded bottom. |
