Veined Mushrooms - Chanterelles and similar looking mushrooms, with undersides ranging from almost completely smooth to veined, but never quite fully gilled. Even though they are not all related, most are mycorrhizal.
Cantharellus (Cantharellales) - the popular chanterelle, medium sized and stocky, coming in orange and white. Note the difference between chanterelle veins and regular gills. 5-15cm or so.
C. cascadensis - often
Hygrophoropsis - this gilled bolete has thinner blade-like gills than the ridges of a chanterelle.
Chroogomphus tomentosus - dry, orange and fuzzy. Another gilled mushroom very often mistaken for a chanterelle.
T. floccosus (bonarii) - orange, but paler more irregular veins, scaly and umbilicate. (Fully described below).
Craterellus (Cantharellales) - contains the very common small winter brown chanterelle and a rare (but very common in California) black chanterelle with barely any hint of veins at all, which might make it difficult to recognize. <10cm.
T. floccosus (bonarii) - orange, but paler more irregular veins, flattened scales and umbilicate (unlike Cantharellus). Fades to brown
Polyozellus mutliplex grp (Thelephorales) - related to many of the tougher stemmed Toothed mushrooms (except Hydnum) and the Boletopsis polypore. The blue chanterelles, rare, growing in large clusters 15cm high and even wider.
Also consider some gilled,
that range from practically smooth underneath to wrinkled or veined, one of which, Clavariadelphus,
is not surprisingly closely related to Gomphus/
Clavariadelphus truncatus - a "club" fungus (click through to see others). <15cm. Gomphales.
Arrhenia retiruga - white to pale grey, practically smooth underneath. ~1cm. Agaricales (Hygrophoroid clade). In moss. Saprophytic.
Muscinupta laevis (Cyphellostereum laeve) - brighter white, almost a stem, unlike A. retiruga. In moss. ~1cm. May be related to the Hymenochaetales. Saprophytic.
Stereopsis humphreyi - <3cm, true stem, and a cleft but not coral fan. Hymenochaetales. Probably saprophytic.
