Fleshy Fungi Commonly EatenBv Southern Wildlife

J

Howard A. Miller and Lowell K. Halls’

Mushrooms appear to be an important com-ponent of the diet for wildlife in the South.They are eaten by deer, small mammals suchas squirrels and other rodents, birds, turtles,and numerous species of insects.

In winter, when the food needs of wildlifeare usually critical, mushrooms are particu-larly important, especially to white-tailed deer.During this period the highly nutritious mush-rooms help to compensate for nutrient defici-encies in native forage.

At the Atomic Energy Commission’s Savan-nah River Project in South Carolina, David F.Urbston of the USDA Forest Service reportedthat deer ate mushrooms at all seasons (un-published data). In an analysis of 100 deerstomachs, he found that 95 percent containedmushrooms or other fungi, varying in volumefrom a trace to 83 percent. Strode (21) listsmushrooms as the most important food for deeron the Ocala National Forest in Florida. Hefound that 79 percent of deer stomachs exam-ined contained mushrooms; percent by volumewas 24. In Missouri, 50 out of 270 deer stom-achs contained fungi (14).

While at the Southeastern Forest ExperimentStation, Charles Cushwa and colleagues col-lected stomach samples from deer in the majorphysiographic provinces of the Southeast. Per-cent of stomachs containing mushrooms rangedfrom 10 to 100, depending on province andseason; content by volume ranged from I to27 percent (unpublished). Use was generallyhighest in summer.

Game birds such as grouse, turkeys, andquail feed heavily on mushrooms. Grouse andturkeys, which are strong scratchers, easilyuncover mushrooms hidden by pine needles or1 Formerly Branch Chief, Wildlife Management, SouthernRegion, USDA Forest Service.

hardwood leaves. Broken ends and threads ofmycelia that have been pulled up indicate thepresence of fungi and use by birds. Quail,being weak scratchers, often feed on pieces ofmushroom left by rodents.

Among rodents that eat mushrooms aresquirrels and white-footed and deer mice. Thewestern gray squirrel feeds heavily on sub-terranean fungi, such as false truffles. Theeastern gray squirrel favors above-groundmushrooms. In Ohio, mushrooms ranked highin the gray squirrel diet (18). In Virginia,fleshy fungi constituted 26 percent of the falldiet and 16 percent of the winter diet of graysquirrels (5).

The fruiting bodies of mushrooms, whichare often heavily infested by insects, are alsoa source of food for birds. Robins and bluejays,for example, frequently tear mushrooms apartin search of larvae.

Four species of mushrooms are preferred farmore than others. In order of preference theyare peppery lactarius (Lactarius piperatus),little red russula (Russula roseipes), honeymushroom (Armillaria mellea), and granulatedbolete (Suillus granulatus).

Purpose of this guide is to aid in identifica-tion of mushrooms commonly eaten by wildlifein the southern forests extending from Texasto Virginia. In addition, the aim is to stimulateinterest in research on mushrooms as wildlifefood and on their ecology and growth.

The fungi described here occur commonly inone or more physiographic provinces of theSouth. They are known to be eaten by one ormore species of wildlife. Their fruiting bodiesare large enough (i.e., at least 2 inches indiameter) to provide a substantial segment ofthe diet for larger birds and mammals. Onlymushrooms that meet these requirements ac-cording to present knowledge are included here.For those interested in additional information,a list of comprehensive manuals is provided.

NUTRITIVE VALUE

Fresh fleshy fungi have high moisture con-tents, usually between 75 and 90 percent. Thus,rather large volumes have to be consumed toprovide adequate protein and phosphorus. Aprotein content of about 30 percent of dryweight has been reported for a typical Mor-chella (17). Crude protein content averaged17 percent (dry weight basis) for several speci-mens of Hygrophorus, Armillaria, Russula,Clitocybe, Tricholoma, Pholiota, and Amanitacollected during late autumn in Georgia; therange was from 12 to 27 percent. Phosphorusaveraged 0.40 percent, ranging from 0.20 to0.58 percent.

In east Texas, specimens of Hygrophorus andAmanita collected during early winter av-eraged 23 percent crude protein and 0.55 per-cent phosphorus. The same samples averagedonly 12 percent in crude fiber content, an indi-cation that they are readily digestible by rumi-nants such as cattle and deer.

Samples of Morchella, Rhizopogon, Cortin-arius, Amanita, Clitocybe, and Lactarius col-lected in May averaged 30 percent crude pro-tein, 17 percent crude fiber, and 0.68 percentphosphorus.

HABITAT REQUIREMENTS

Fleshy fungi are particularly abundant inthe litter on the forest floor. Some fungi arefound only in association with conifers andothers with hardwoods. Some seem to be de-pendent upon a single tree species. A few areparasitic on other mushrooms. Certain fungiare especially numerous in soils where organiccontent is high. A few live mainly on the slashleft after logging of hardwoods. Many estab-lish a mycorrhizal association with tree roots.

The mushroom population in the forestchanges with the seasons. Morchella, or morels,usually appear in the coolness of early spring,Boletus in the summer, Cortinarius in autumn,Hygrophorus in early winter, and Collybiaduring winter (15).

The greatest number of species are usuallyfound where the forest floor is covered withsufficient humus, dead leaves, thick moss, orother debris to hold moisture. Mycelia canlive for many years, and mushrooms are oftenfound in about the same spot each year. During

2

a drought, fruiting bodies are seldom seen, anda long rainy spell may be necessary before theyappear above ground. Except where rottenlogs and woods retain moisture, a single heavyrain or even a number of scattered showersmay not be sufficient to induce growth (12).

Certain conditions of temperature and hu-midity must be present even when soil mojs-ture is ample. Commercial mushrooms growsbest between 50” and 60°F.. but in the wildthere is a wider tolerance (15). If showersoccur frequently during warm weather, a largenumber of species can be found fruiting simul-taneously in a small area (20).

Since mushrooms lack chlorophyll and gettheir food from organic matter, direct sunlightis not necessary for growth. The mycelium iscapable of fruiting even under dense shade,given the proper temperature and moisture.This characteristic will become increasinglyimportant in management of game habitat un-der dense pine stands grown on short rotations.

Any forest management practice that resultsin disturbance to the soil or an accumulationof derbis and organic material will usuallyaffect the mushroom population. Species ofmushrooms that live on slash and downed treesshould increase for several years followinglogging. Later, as the debris breaks down,additions to the duff provide a medium onwhich a large number of mushrooms of otherspecies live.

Burning, an important management tech-nique, often causes certain fungi to fruit fora few years, after which they are not seenuntil the next burn. On six burned plots ofloblolly and shortleaf pines (Pinus taeda, P.echinata), the senior author observed that fireapparently induced heavy fruiting of Suillusgranulatus, R u s s u l a delica, R . variata, Arm-illaria ventricosa, and Hygrophorus tennesseen-sis. On the other hand, where fire destroys asubstantial proportion of the litter, the numberand kinds of fleshy fungi will probably decline.

In southern forests where upland hardwoodshave been converted to pines, certain mush-rooms that were scarce or absent among thehardwoods become abundant. Species such asAmanita verna, A. chlorinosma, and Lactariuspiperatus tolerate the high density of youngstands and the lack of hardwood litter anddebris.

Amanita

Amanitas are eaten by deer, squirrel, turkey,grouse, and other birds and mammals. Mostof them are deadly to humans, however.

These beautiful mushrooms range in colorfrom pure white to brilliant red and orange.The spores are white and the gills are free oronly slightly attached to the stem. The outerveil, when broken, becomes the volva or cupat the base of the stem. The inner veil, whenbroken, becomes the ring on the stem.

Species described here are common in south-ern pine-hardwood forests.

Lactarius

Members of this genus are among the largestand showiest mushrooms in the woods. Theyare highly attractive to insects, rodents, anddeer. An untouched, mature specimen is rarelyfound.

Species range from about 4 inches in diame-ter to as large as a dinner plate. They havewhite spores and attached or decurrent gills.Cap and stem are continuous. The cap is moreoften depressed to funnel-shaped. The singlemost distinguishing character is the presenceof white or colored juice when the cap isbroken. In wet weather, droplets often oozefrom the gills. Droplets are not visibly exudedfrom old dry specimens; a low-power lens maybe required to distinguish their presence.

The genus is well distributed in the moun-tains, the Piedmont, and Coastal Plains, as wellas on flood plains of the major rivers. It ismostly terrestial, sometimes on much decayedwood. Lactarius species often occur in largenumbers in the open woods of higher ground.

BoletaceaeMembers of the Boletaceae are large and

common enough to furnish a substantial a-mount of food to deer as well as to squirrelsand other rodents.

Boletes differ from other parasol-shapedmushrooms in that tubes have replaced gillsas reproductive surfaces. From the outside thetubes resemble pores; thus the boletes areoften referred to as pore mushrooms. Cokerand Beers (1943) list 68 species and six varie-ties in North Carolina; there are probablymany more yet to be described. They occuron many sites, but those that grow in the soilappear most attractiye to wildlife.

Three important- points help to determinegenus and species of boletes: ease with whichthe cap and tubes can be separated, charac-ter of the cap and stem surface, and changesin flesh and tube coloring resulting from in-jury.

Most species of boletes are brilliantly col-ored. Certain species are noted for their my-corrhizal relationship with several tree species-principally conifers.

Boletes described here are usually found inpine and hardwood forests from the CoastalPlain to the mountains.

Other Fleshy FungiThe other fleshy fungi that are commonly lies : Lycoperdaceae, Clavariaceae, Hymeno-

eaten by wildlife belong mainly to four fami- gastraceae, and Helvellaceae.

Calvatia

This genus belongs to the family Lycoper-daceae, a group of fungi known as puffballs,smokeballs, and devil’s snuffboxes. These fungihave spores enclosed until maturity in cham-bers surrounded by a continuous skin. Theyspend most of their lifetime underground, get-ting food from decaying vegetable matter.When about ready to scatter their spores, theyemerge from the ground.

The balls have a fleshy interior; cheesy andwhite at first, they turn yellowish or pinkish,gradually darkening until part or all of theinterior .becomes filled with dust-like spores.

In Calvatia, the wall of the upper part ofthe fruit body breaks up and disappears atmaturity, thus exposing the spore mass. Thestalk-like base, with a structure suggesting ahoneycomb, may remain in place long after thespores have been blown away.

The giant puffball has a thick tapering basecomposed of spongy mycelium, distinct fromthe spore-bearing part above. It occurs in allprovinces from August to November.

Clavaria

This genus belongs to the family Clavaria-ceae, the club fungi. It includes a large num-ber of species, many of which are identifiableonly by microscopic details. Those eaten bywildlife are fleshy, erect, and repeatedlybranched. They are commonly referred to as“coral fungi,‘.’ because of their resemblance tostructures built by this marine animal.

Deer, in particular, graze on the succulentfleshy tops of the coral fungi. Groups of thefungi ranging from 4 to 8 inches in diameteroccur in pine and hardwood types. Often thesegroups number in the hundreds. Clavariasoccur from the mountains to the Coastal Plainsand fruit during July and August. They donot appear to do well in the fall months.

Clavaria sp.

FRUITING 4 to 8 inches in diameter, usuallyBODY branched, erect

RhizopogonRhizopogon belongs to the family Hymeno-

gastraceae. The fruiting bodies, commonlyknown as false truffles, form just beneath thesurface of the ground. While in the under-ground stage they are eaten by squirrels andother rodents. They appear to have no attrac-tion once they emerge from the ground.

False truffles generally occur in grassy areasor under pine straw at the edges of pine standsin fall and winter. Careful searching whererodents have been digging may reveal an un-derground portion that is often from 6 to 12inches below the surface.

MorchellaThis genus belongs to the family Helvella-

ceae, a group that has a fruiting body con-sisting of a stalk and an enlarged cap that ispitted. Some species fruit in recent burns,others in cultivated soil.

In MorcheZZa, the morels, the surface of thebell-shaped cap has prominent irregular ridgesthat resemble the surf,ace of a sponge. Thestem is fluted and hollow, often containingholes where insects have emerged; it is lighterin color than the head. The head, or cap, like-wise is hollow; darker in color, it is composedof folded, narrow, long, sac-like cells in whichthe spores are contained. The spores are“squirted” out at maturity.

There are several species of morels in theSouth. The common morel has the widestdistribution and is probably best known. Itfruits in March and early April.

Morels grow in deep soils along streamsunder hardwoods-usually oaks-and in oldapple orchards from the Coastal Plain to themountains. They are readily taken by mostmammals.
