| Morphological Description
|
colour of cap ranges from dark-brown or medium-brown with silvery undertones to dark gray. The stipe is a similar color but sometimes a little lighter in shade
-Cap flavor: slowly peppery (after about 4 seconds)
-Latex is milky-white and it does not change color readily (even after 5 hours of exposure)
-No obvious staining of the gills of cap tissue
-Spores are broadly ellipsoid, and amyloid ornamentations which form a reticulum. The spore ornamentation is 0.5-1 micrometers tall.
-I was not able to get a spore print.
-Basidia are clavate
-Pleurocystidia: macrocystidia 60-90 X 7-11 micrometers and are elongate-fusoid. Cheilocystidia present (similar in shape to macrocystidia but smaller).
-Lactifers throughout gill and cap tissue
-Sphaerocysts are numerous in the cap tissue
-Note that usually Lactarius pseudomucidus has a stipe that is fragile and breaks like chalk. Many of my specimens have stipes that are a little bendy. This might be because of unusual whether conditions (perhaps the weather was drier than usual and the stems were a bit "limp") |
