Miscellaneous white spored Wood-inhabiting Mushrooms

All are saprophytic (or parasitic!) on conifers (or not fussy) unless otherwise specified.

Pleurotus/Panus are large mushrooms on wood that usually have eccentric stems/tough fruitbodies, and therefore are found on the Oddballs page, but they might appear normal and be looked for on this page. Neolentinus/Lentinellus have serrated gill edges, but that is easy to overlook.
Gymnopus and other collybioid fungi with tough stems can sometimes be found on wood. Consider them too.
Also consider two small (<5cm) rare, whitish, decurrent Clitocybes that grow on wood. (C. americana and C. truncicola)

Key:

Armillaria - the honey mushroom - a popular edible, but there are a half a dozen species that have recently been separated from each other and some people react negatively to some of them (with some people thinking that Armillarias growing on hardwood are more likely to upset your stomach). The previously unknown different species have led to this mushroom getting the nickname "The mushroom of a thousand faces", as there may or may not be a lot of scales on the cap and stem, a well developed ring or just a slight partial veil, and they can range from small to quite large. But they will always be larger than most other mushrooms in this category, have some kind of a partial veil and a stem that looks like it was stuffed with a cottony pith. They grow on wood (sometimes buried and appearing from the ground) sometimes in large clusters and are in the Marasmioid clade. A very common parasite. Usually 5-10cm except for the larger species. Many species have glow in the dark mycelium (bioluminescence).

A. nabsnona - slender, orange-brown cap with few cap scales, spring or fall, prefers alder.

A. mellea - less slender, fall, in large clusters, the only species without a bulbous stem base. Southern species. Hardwoods?

A. ostoyae (solidipes) - stout, dark or pale brown, much scalier. (usually conifers), usually with the most developed ring of any species.

A. sinapina - like A. ostoyae, but more often with golden yellow universal veil remnants.

A. gallica - only slightly scaly, often with a bulbous stem. Hardwoods.

A. cepistipes - larger, somewhat scaly. The only one noted to sometimes have marginate gills. Hardwoods.

The cottony pith inside the stem of Armillaria spp.

 

Tricholomopsis - very beautiful colourful mushrooms on wood. Probably in the Hygrophoroid clade. Usually around 5cm.

T. rutilans - pink with black scales, bright yellow gills. Resembles Gymnopilus luteofolius. May get >5cm.

T. decora - bright yellow everywhere with black scales.

T. flavissima - scales not black, gill edges are yellow marginate.

T. thompsoniana - flesh stains yellow when handled. Balder cap than the others.

T. bella - gills and stem stain brown when handled.

T. sulphureoides - a rather nondescript species (although still a beautiful yellow).

 

Flammulina - this is what Enoki looks like in the wild, and the amazing morphologic change into a needle-thin long stemmed mushroom with a pinprick head and smooth white stem is an astonishing example of how environmental conditions can change a species. On the small side, with a dark velvety stem when mature (and difficult to ID before then). Not hygrophanous. Grows on hardwood. Not uncommon in the spring and fall. Usually <5cm. Related to Armillaria. Japanese growers (who are usually heavy consumers) of this mushroom in Nagano were found to have much lower cancer rates than those in other Japanese provinces.

F. velutipes - orange-brown cap, may be viscid.

F. populicola - usually the dark species growing on cottonwood/aspen.

F. rossica - much paler.

 

Other miscellaneous mushrooms - usually adnexed to adnate gills.

Hypsizygus tessellatus - the store bought "elm oyster". Tan cap with water spots. May be farinaceous. Hardwood. Not hygrophanous. Related to Lyophyllum.

Clitocybula familia - tan (to grey), very clustered. Resembles Mycena overholtsii. Usually <2.5cm. Marasmioid clade. Amyloid spores (darkening in iodine).

C. abundans - grey, sometimes streaked. Less clustered, slightly umbilicate. Usually <4cm.

C. lacerata - bigger, cap more likely to split. <6cm.

Baeospora myriadophylla - found on logs, crowded purple gills keep their colour longer than the rest of this purple-tinged mushroom. Marasmioid clade.

Megacollybia platyphylla grp (M. fallax) - large (but <10cm) grey-brown cap sometimes with radial streaks that split, gill edges that might get eroded in age, and some white rhizomorphs at the stem base. Not hygrophanous. Marasmioid clade.

Gymnopus (Collybia) bakerensis - <4cm. Mostly white with a pinkish brown stem base, growing on wood. Less crowded gills than Ossicaulis. Not hygrophanous.

Callistosporium luteoolivaceum - a kind of greasy olive yellow-brown. Not hygrophanous. Hard to ID, especially when the olive colour has faded or when growing from the ground from buried wood. Probably in the Tricholomatoid clade. 5cm or less.

Usually decurrent gills.

Ossicaulis lignatilis - pure white, crowded gills of variable attachment. Stem sometimes off centre. Resembles Clitocybe truncicola and Collybia bakerensis, but is purer white in age with a stronger fungal-farinaceous odor. Hardwoods. Not hygrophanous. Related to Lyophyllum.

Clitocybula atrialba - distinguished from Clitocybe by its long thin stem and dark cap and stem. On hidden hardwood but appearing terrestrial. Resembles Pseudoclitocybe. <10cm. Not hygrophanous.

Pseudoarmillariella ectypoides - Strongly decurrent, yellowish gills. Not hygrophanous. Hygrophoroid clade, and it does somewhat resembles the smaller Chrysomphalina chrysophylla, which is more colourful and less strongly decurrent. 5cm or less. Amyloid spores.

Pseudoclitocybe cyathiformis - resembles Arrhenia, Clitocybula atrialba and Ampulloclitocybe with its dark cap and stem and is also found on buried wood growing from the ground, but is not usually as dark or tall or thin-fleshed. Hygrophanous. Hygrophoroid clade. Around 5cm. Amyloid spores.

Mycena overholtsii - marasmioid stature, arcuate gills and fuzzy stem. Snowmelt. Resembles Clitocybula.

 

Again, as this is a miscellaneous page, there is no specialized literature available for this artificial group.
