Literature :
Ota, Y; Hattori, T; Nakamura, H; Terashima, Y; Lee, S.S; Miyuki, Y; Sotome, K. 2014. Taxonomy and phylogenetic position of Fomitiporia torreyae, a causal agent of trunk rot on Sanbu-sugi, a cultivar of Japanese cedar (Cryptomeria japonica) in Japan. Mycologia. 106(1):66-76

Page number : 70
Remarks (internal) : The holotype of F. torreyae was not traced. Dai and Cui (2005) described it as lacking hymenial setae. However, setae were present in all examined specimens. It is a variable species for perenniality, pore size, frequency of hymenial setae and basidiospore size. Basidiocarps produced on Cryptomeria and Chamaecyparis are usually annual and have shorter tubes, but other morphological characteristics are not related to their host-tree species. This fungus hitherto is known only from warm areas in China and Japan.

Description : Fomitiporia torreyae Y.C. Dai & B.K. Cui, Mycotaxon 94:344 (2005) Figs. 3,4

Basidiocarps resupinate, annual to perennial. Pores round, 4-6 to 7-8/mm; pore surface yellowish brown (10YR 6/8), light brown (10YR 6/4) to brown (10YR 5/4), glancing; dissepiments entire. Margin inconspicuous, membranous, almost concolorous with the pore surface, usually less than 1 mm wide. Tubes corky to leathery, stratified or not, tube length variable, up to 5 mm deep in each layer. Subiculum thin, almost lacking, without black line between subiculum and substrate.

Hyphal system dimitic. Trama hyphae regular to subregular not agglutinated. Trama generative hyphae occasionally branched, simple septate, thin- to slightly thick-walled, 1.5-3 µm diam. Trama skeletal hyphae almost straight to sinuous, thick-walled with a distinct lumen, aseptate, light brown to brown, 2-4 µm diam. Hymenial setae variably present according to specimens, sparse, scattered, or abundant at limited portions of tubes; ventricose to shortly ventricose with swollen base, occasionally acuminate, 15-30 × 6-10 µm. Basidiospores subglobose, slightly thick-walled, hyaline, dextrinoid, 4-6.5 × 3.5-6 µm (av. 5.34 × 4.91, r = 1.01-1.22, r = 1.09, n = 547/14, individual average range 4.88 × 4.43-5.76 × 5.40 µm).

Type of rot: White.

Distribution and substrate: Warm and subtropical areas in eastern China and central Japan. Most frequent on living and recently killed cultivated conifers (Cephalotaxus harringtonia forma fastigiata, Chamaecyparis pisifera, Cryptomeria japonica, Podocarpus macrophylleus, Sciadopitys verticilliata) but also on living cultivated or garden broadleaf trees (Chionanthus retusus, Pyrus pyrifolia var. culta, Prunus mume, Rhododendron kaempferi, Spiraea thunbergii, Tilia miqueliana). Holotype on living Torreya grandis in natural forest of eastern China. Occasionally on living and dead standing trees of hardwood in natural forests, but infrequent.
