Description:Aleurodiscus botryosus Burt Fig. 14 Ann. Mo. Bot. Gard. 5:198,1918.
Basidiocarp corticioid, first as separate patches 2-4 mm in diam., about 1 mm thick, later effused, margin determinate, adnate, pruinose-pulverulent, hymenophore white to pale buff-coloured, smooth to rimose when old. Hyphal system monomitic, thin-walled hyphae with simple septa, more thickwalled in the subiculum.
Acanthophyses (botryophyses) cylindrical to clavate with numerous, small, strongly amyloid, cluster-like branches in the apex, a few sparingly branched and reminiscent of dendrohyphidia. Gloeocystidia variable, cylindric, clavate to ventricose or fusiform with a tapering, simple to bifurcate apex, 38-90 x (7)12-19 µm, yellowish in KOH. Basidia short-clavate to subclavate, 35-55 x 12-15 µm, with 4 sterigmata. Basidiospores ovoid to subglobose, 12-15 (18) x (7)8-11 µm, echinulate.
Cultural characteristics. See Boidin et al. (1968).
Substrata. Hardwoods, recorded from a wide host range such as juniperus, Acer, Lonicera, Myrica, Ostrya, Quercus, Symphiocarpus, Syringia, Thuja, Vitis, Rosa. Distribution. Widespread in warm temperate to subtropical areas in the northern hemisphere, the northernmost locality in Europe seems to be the Czech Republic. Known from Zimbabwe and Zaire, and probably widespread in Africa. Also recorded from New Zealand.
Remarks. The amyloid botryophyses are diagnostic for this species. The species is the type of Aleurobotrys Boidin
