Remarks (internal):As outlined here, Antrodia sensu stricto represents a small group of species with a few good characters to distinguish it from other Antrodia species. Characteristic are large, short-lived pedunculate basidia, slightly thick-walled hymenial cells and spore shape (fusiform distal end). The unique character of this group is the presence of hyphidia, sterile slender outgrowths that occasionally divide into two or three apical branches, especially common in mature or senescent hymenium. They are often difficult to find, though.
We call skeletal hyphae bending into hymenium as skeletocystidia in this paper for want of a better term. Apex of these hyphae is slightly widened, but otherwise they are not differentiated from other skeletal hyphae.
Majority of the dimitic specimens of Antrodia sensu stricto are sterile, and the sporulation period appears to be short; between sporulation the hymenium hibernates as slightly thick-walled basidioles. Fertile specimens were commonly collected in the spring as well. DNA extraction and sequencing seems to be exceptionally easy in this group, and wemanaged to sequence many over 20 year old specimens and several over 30 year old specimens with standard techniques. This is not the norm for polypores or other Antrodia spp.
Coriolellus Murrill 1905, typified by Trametes sepium (5 Antrodia favescens), is a taxonomic synonym of Antrodia sensu stricto.

Description:Antrodia P. Karst.
Medd. Soc. Fauna Flora Fennica 5:40, 1879.
Type species: Daedalea serpens Fr. (lectotypified by Donk 1960:186)
Other members: A. favescens, A. heteromorpha, A. macra, A. mappa, A. tanakai, plus several undescribed species from the tropics.
Resupinate to pileate brown-rot polypores with annual, white to cream basidiocarps and middle-sized to large pores (0.5-4 per mm). Hyphal system dimitic with clamped generative hyphae, nearly monomitic in one species, skeletal hyphae hyaline, fairly narrow (2.5- 4.3 µm wide), unbranched and tightly arranged, CB-, IKI-, KOH-, CRB lilac, lumen usually indistinct. Basidia clavate and large, 20-50 3 5-10 µm, slightly thickwalled and with long sterigmata. Poorly differentiated skeletocystidia (ends of skeletal hyphae penetrating hymenium), cystidioles (appearing as basidioles with a secondary hyphal outgrowth), and hyphidia present, though rare. Spores long (6.5-12 µm), cylindrical to narrow ellipsoid, with a tapering distal end. Spores are not thick-walled, but the wall is distinct.
