Monthly counts, in plantations of
Fruitbodies rarely appeared in the absence of rain. Average monthly numbers increased in rain-months from 11 to 320 per thousand trees when monthly rainfall increased from 40 to 640 mm.
During a period of 11 months (February/December 1978) numbers of fruitbodies per 1000 trees ranged from
After rainfall-thresholds for fruitbody production had been exceeded—they were less in old, than in young, plantations—young plantations, judged by the production of

The production of fruitbodies of fungi forming sheathing (ecto-) mycorrhizas with trees depends upon current supplies of host assimilates, upon host genotype and the age of the host tree, upon soil types and soil amendments, and weather.
Fruitbodies are not produced by fungi on roots severed from their tree, nor are they produced when trees are naturally or artificially defoliated. As trees, planted in ‘new’ sites, increase in age a succession of fungi produce fruitbodies, most arranged in annuli (rings) but some are arranged linearly, seemingly along secondarily thickened roots. From the initial ‘focus’, a stem base, each ring progresses outwards at rates comparable to those of grassland fairy ring fungi (10–20 cm yr−1), the movement of different rings being spatially correlated. Around birch trees in brown earth soils, rings of early stage fungi (

With an increasing interest in the use of selected fungi for the production of sheathing (ecto-) mycorrhizas by controlled inoculations, attempts were made to identify collections of
Although the sizes of individual fruitbodies within collections varied appreciably, it was nonetheless possible to sort the collections into 2 groups using mean sizes: one group with (i) stipes (stalks) about 7 mm long and 1 mm diam. and (ii) pilei (caps) 10 mm diam., and a second group with appreciably larger fruitbodies.
The group of larger fruitbodies was found to contain collections with either 2- or 4-spored basidia; the basidia in the group of small fruitbodies were all 2-spored.
Although of similar sizes, spores of the 4-spored specimens had different shapes as judged by the ratios (
The spores of the group of large fruitbodies with 2-spored basidia were globose, like those of
