al. 1997); edible and known as the American Matsutake or White Matsutake,
collected in the west under Douglas fir and Ponderosa pine for export to Japan
(Redhead 1989, Bessette et al. 1997); in northern Michigan it is as highly prized
and as sought after by collectors in the fall as the morel mushroom is in the
spring; Armillaria ponderosa Pk., is the name used in early HMWF reports
(Richter 1996, 1997).
Volvariella bombycina (Schaeff. ex Fr.) Singer (Pluteaceae)
23 Aug 2002, T52N, R28W, Sec 27, SW of Cranberry Bog, maple log, two fruiting bodies, hmc-02-009, (Fig. 8).
Fruiting body fleshy; height 8.2-12.6 cm; pileus 5.4-9.2 cm, silky-white, fibrillose; gills off-white; stipe white, enclosed at base by a membranous, light brown
volva remaining intact when mature; on wood; a strikingly beautiful mushroom
causing a white-rot of hardwoods; Burdsall (1974) reported it from the Huron
Mountains on maple near Ives Lake (col. #8241); Dr. William Manierre (personal communication) also found it near Mountain Lake 28 Aug 1989; Miller
(1980) says rare; Bessette et al. (1997) say occasional; Lincoff (1981) says not
common; curiously it is not included in Phillips (1991), perhaps due to its rarity;
this is only the second time the author has encountered it.
